Description
本發明係關於線鋸機用之線鋸鋼線，詳言之，係關於切斷金屬或陶瓷等之工件時，於線鋸鋼線上吹入研磨粒而使用之線鋸鋼線用之基底鋼線。The present invention relates to a wire saw steel wire for a wire saw machine, and more particularly to a base steel for wire sawing steel wire which is blown into a wire saw steel wire when cutting a metal or ceramic workpiece. line.
金屬或陶瓷等之工件係以安裝線鋸鋼線之線鋸機切斷。線鋸鋼線以單向或雙向(往復方向)行進，藉由使該線鋸鋼線與工件接觸，以任意寬度切開工件。A workpiece such as metal or ceramic is cut by a wire saw machine equipped with a wire saw steel wire. The wire saw steel wire travels in a one-way or two-way (reciprocating direction), and the workpiece is cut at an arbitrary width by bringing the wire saw steel wire into contact with the workpiece.
工件係將含有研磨粒(以下有時稱為游離研磨粒)之溶液吹送到線鋸鋼線，一面切斷。吹送之溶液中所含之游離研磨粒進入到工件與線鋸鋼線之間，藉由促進工件之磨耗而切斷工件。In the workpiece, a solution containing abrasive grains (hereinafter sometimes referred to as free abrasive grains) is blown to a wire saw steel wire and cut off. The free abrasive particles contained in the blown solution enter between the workpiece and the wire saw steel wire, and the workpiece is cut by promoting wear of the workpiece.
至於一面吹送含游離研磨粒之溶液一面切斷工件時所用之線鋸鋼線，於專利文獻1中揭示以研磨粒載體樹脂皮膜被覆高碳鋼線等鋼線之外周面之線鋸鋼線。記載有若使用該線鋸鋼線，則游離研磨粒會咬入研磨粒載體樹脂皮膜中，因此線鋸鋼線與工件接觸之部份可安定地引入游離研磨粒。In the wire saw steel wire used for cutting a workpiece while blowing a solution containing free abrasive grains, Patent Document 1 discloses a wire saw steel wire which is coated with a peripheral surface of a steel wire such as a high carbon steel wire by an abrasive grain carrier resin film. It is described that if the wire saw steel wire is used, the free abrasive grains bite into the abrasive grain carrier resin film, so that the portion of the wire saw steel wire that is in contact with the workpiece can be stably introduced into the free abrasive grains.
專利文獻1：日本國特開2006-179677號公報Patent Document 1: Japanese Patent Laid-Open Publication No. 2006-179677
上述專利文獻1所揭示之線鋸鋼線係利用研磨粒載體樹脂皮膜直接被覆鋼線之外周面。因此，研磨載體樹脂皮膜自鋼線剝離時，會使鋼線本身露出，在工件切斷時藉由供給之游離研磨粒而急劇進行鋼線之磨耗，而有使鋼線斷線之情況。另外，以研磨載體樹脂皮膜被剝離之鋼線切斷工件時，所切斷之工件之表面精度變差，使工件品質下降。The wire saw steel wire disclosed in the above Patent Document 1 directly coats the outer peripheral surface of the steel wire with the abrasive grain carrier resin film. Therefore, when the polishing carrier resin film is peeled off from the steel wire, the steel wire itself is exposed, and when the workpiece is cut, the steel wire is sharply worn by the supplied free abrasive grains, and the steel wire is broken. Further, when the workpiece is cut by the steel wire from which the carrier resin film is peeled off, the surface precision of the workpiece to be cut is deteriorated, and the quality of the workpiece is deteriorated.
本發明係鑑於該狀況而完成者，其目的係提供一種於表面形成有機皮膜之被覆線鋸鋼線用之基底鋼線，係可抑制有機皮膜剝離之基底鋼線。且，本發明其他目的係提供一種有機皮膜之耐剝離性優異之被覆線鋸鋼線。The present invention has been made in view of the above circumstances, and an object thereof is to provide a base steel wire for a coated wire saw steel wire having an organic film formed on its surface, which is a base steel wire capable of suppressing peeling of an organic film. Further, another object of the present invention is to provide a coated wire saw steel wire which is excellent in peeling resistance of an organic film.
可解決上述課題之本發明之基底鋼線為表面具有有機皮膜之被覆線鋸鋼線用之基底鋼線，其特徵為具有鋼線及形成在前述鋼線表面上之鍍敷層。The base steel wire of the present invention which can solve the above problems is a base steel wire for a coated wire saw steel wire having an organic film on its surface, and is characterized by having a steel wire and a plating layer formed on the surface of the steel wire.
上述鍍敷層列舉為例如含有Cu及/或Zn之層。上述鍍敷層表面之算術平均粗糙度Ra較好為0.2μm以下。附著於上述鍍敷層表面上之油較好為每1g基底鋼線為70μg以下。附著於上述鍍敷層表面上之附著物之碳成分較好為每1m之基底鋼線為15μg以下。The plating layer is exemplified by a layer containing Cu and/or Zn, for example. The arithmetic mean roughness Ra of the surface of the plating layer is preferably 0.2 μm or less. The oil adhering to the surface of the plating layer is preferably 70 μg or less per 1 g of the base steel wire. The carbon component adhering to the surface of the plating layer is preferably 15 μg or less per 1 m of the base steel wire.
本發明之被覆線鋸鋼線之特徵為具有上述被覆基底鋼線之有機皮膜。The coated wire saw steel wire of the present invention is characterized by having the above-mentioned coated base steel wire organic film.
本發明亦包含一種切斷體之製造方法，係將研磨粒吹送到上述被覆線鋸鋼線，以前述被覆線鋸鋼線將工件切斷成切斷體。The present invention also includes a method of producing a cut body by blowing abrasive grains onto the coated wire saw steel wire, and cutting the workpiece into a cut body by the covered wire saw steel wire.
本發明之基底鋼線具有鋼線與形成於鋼線表面之鍍敷層，該鍍敷層之表面形成有機皮膜。鍍敷層之作用為提高鋼線與有機皮膜之密著性，可提高有機皮膜之耐剝離性。The base steel wire of the present invention has a steel wire and a plating layer formed on the surface of the steel wire, and the surface of the plating layer forms an organic film. The role of the plating layer is to improve the adhesion between the steel wire and the organic film, and to improve the peeling resistance of the organic film.
上述專利文獻1所揭示之利用被覆線鋸鋼線切斷工件時，有機皮膜會自鋼線表面剝離，有導致線鋸鋼線斷線或工件表面之面精度不良之情況。本發明者針對其原因進行檢討後，判知由於鋼線表面生成之氧化鐵使鋼線與有機皮膜之密著性變差，故有機皮膜容易自鋼線表面剝離。因此本發明人等為改善鋼線與有機皮膜之密著性而重複積極檢討。其結果，本發明人等發現若在鋼線與有機皮膜之間形成鍍敷層，則可提高鋼線與有機皮膜之密著性而可改善有機皮膜之耐剝離性，因而完成本發明。When the workpiece is cut by the coated wire saw steel wire disclosed in Patent Document 1, the organic film is peeled off from the surface of the steel wire, and the wire saw wire is broken or the surface of the workpiece is poor in accuracy. The inventors of the present invention examined the cause and found that the iron oxide formed on the surface of the steel wire deteriorates the adhesion between the steel wire and the organic film, so that the organic film is easily peeled off from the surface of the steel wire. Therefore, the inventors of the present invention repeated active reviews to improve the adhesion between the steel wire and the organic film. As a result, the present inventors have found that when a plating layer is formed between the steel wire and the organic film, the adhesion between the steel wire and the organic film can be improved, and the peeling resistance of the organic film can be improved, and thus the present invention has been completed.
亦即本發明之基底鋼線之特徵為鋼線表面具有鍍敷層。藉由於鋼線表面形成鍍敷層，可提高鋼線與有機皮膜之密著性。That is, the base steel wire of the present invention is characterized in that the steel wire surface has a plating layer. By forming a plating layer on the surface of the steel wire, the adhesion between the steel wire and the organic film can be improved.
上述鍍敷層較好為由比鋼線柔軟且延展性較優異之金屬所成之鍍敷層者。列舉為例如，含有由Cu、Zn及Ni所成群組所選出之至少一種之鍍敷層。該等元素中，較好為含有Cu及/或Zn之鍍敷層。Ni由於為較昂貴之金屬，故含有Ni之鍍敷層成本較高。The plating layer is preferably a plating layer made of a metal which is softer than steel wire and has excellent ductility. For example, it is a plating layer containing at least one selected from the group consisting of Cu, Zn, and Ni. Among these elements, a plating layer containing Cu and/or Zn is preferred. Since Ni is a relatively expensive metal, the plating layer containing Ni is expensive.
含有Cu之鍍敷層可例示為Cu鍍敷層、Cu-Sn合金鍍敷層等。含有Zn之鍍敷層可例示為Zn鍍敷層等，含有Ni之鍍敷層可例示為Ni鍍敷層等。含有Cu及Zn之鍍敷層可例示為黃銅(brass)鍍敷層。含有Cu及Ni之鍍敷層可例示為Cu-Ni合金鍍敷層、Cu-Ni-Sn合金鍍敷層等。The plating layer containing Cu can be exemplified by a Cu plating layer, a Cu-Sn alloy plating layer, or the like. The plating layer containing Zn can be exemplified as a Zn plating layer or the like, and the plating layer containing Ni can be exemplified by a Ni plating layer or the like. The plating layer containing Cu and Zn can be exemplified as a brass plating layer. The plating layer containing Cu and Ni can be exemplified by a Cu-Ni alloy plating layer, a Cu-Ni-Sn alloy plating layer, or the like.
經最終線伸長成為被覆線鋸鋼線時，上述鍍敷層之厚度較好為例如0.1~0.5μm(較好為0.2~0.4μm，更好為0.25~0.35μm)。鍍敷層太薄時，無法充分改善有機皮膜之耐剝離性。但，鍍敷層太厚時，有機皮膜之耐剝離性改善效果達飽和，且製造上亦變困難。When the final wire is elongated to form a covered wire saw steel wire, the thickness of the plating layer is preferably, for example, 0.1 to 0.5 μm (preferably 0.2 to 0.4 μm, more preferably 0.25 to 0.35 μm). When the plating layer is too thin, the peeling resistance of the organic film cannot be sufficiently improved. However, when the plating layer is too thick, the effect of improving the peeling resistance of the organic film is saturated, and it is difficult to manufacture.
上述鍍敷層表面之算術平均粗糙度Ra較好為0.2μm以下。鍍敷層之表面太粗時，工件切斷時應力集中而容易造成有機皮膜之剝離。據此，鍍敷層表面之算術平均粗糙度Ra較好為0.2μm以下，更好為0.15μm以下，又更好為0.1μm以下。又，鍍敷層表面之算術平均粗糙度Ra之下限並無特別限制，但Ra太小時有機皮膜之耐剝離性改善效果達飽和同時製造上困難。據此，Ra之下限為例如0.01μm，較好為0.03μm，更較好為0.05μm。The arithmetic mean roughness Ra of the surface of the plating layer is preferably 0.2 μm or less. When the surface of the plating layer is too thick, the stress is concentrated when the workpiece is cut, and the peeling of the organic film is liable to occur. Accordingly, the arithmetic mean roughness Ra of the surface of the plating layer is preferably 0.2 μm or less, more preferably 0.15 μm or less, still more preferably 0.1 μm or less. Further, the lower limit of the arithmetic mean roughness Ra of the surface of the plating layer is not particularly limited, but when Ra is too small, the effect of improving the peeling resistance of the organic film is saturated and it is difficult to manufacture. Accordingly, the lower limit of Ra is, for example, 0.01 μm, preferably 0.03 μm, and more preferably 0.05 μm.
上述鍍敷層表面之算術平均粗糙度Ra可以例如雷射顯微鏡，以倍率1000倍觀察而測定。The arithmetic mean roughness Ra of the surface of the plating layer can be measured, for example, by a laser microscope at a magnification of 1,000 times.
上述鍍敷層表面之算術平均粗糙度Ra可藉由調整鍍敷種類、鍍敷厚度、線伸長時使用之模核之表面精度、線伸長時之線伸長速度、線伸長時使用之潤滑劑種類、或潤滑劑之溫度等控制。The arithmetic mean roughness Ra of the surface of the plating layer can be adjusted by the type of plating, the thickness of the plating, the surface precision of the core used for the elongation of the wire, the elongation rate of the wire during the elongation of the wire, and the type of the lubricant used for the elongation of the wire. , or the temperature of the lubricant, etc.
表面形成上述鍍敷層之鋼線可使用例如不銹鋼鋼線或高碳鋼線等。不銹鋼鋼線可使用例如SUS301、SUS304、SUS310、SUS316、SUS321、SUS347等奧斯田鐵(austenite)系不銹鋼鋼線，SUS405、SUS430等亞鐵酸鹽(ferrite)系不銹鋼鋼線、SUS403、SUS410等麻田散鐵(martensite)系不銹鋼鋼線、SUS329J1等二相不銹鋼鋼線(奧斯田鐵‧亞鐵酸鹽系不銹鋼鋼線)、SUS630等析出硬化系不銹鋼鋼線等。至於高碳鋼線可使用例如含有0.5~1.2%C之高碳鋼線。該高碳鋼線可使用例如JIS G3502所規定之鋼琴線。For the steel wire having the above-mentioned plating layer formed on the surface, for example, a stainless steel wire or a high carbon steel wire or the like can be used. For the stainless steel wire, for example, austenite-based stainless steel wire such as SUS301, SUS304, SUS310, SUS316, SUS321, or SUS347, or a ferrite-based stainless steel wire such as SUS405 or SUS430, SUS403, SUS410, or the like can be used. Martenite is a stainless steel wire, a two-phase stainless steel wire such as SUS329J1 (Aosta iron and ferrous ferritic stainless steel wire), and a hardened stainless steel wire such as SUS630. As for the high carbon steel wire, for example, a high carbon steel wire containing 0.5 to 1.2% C can be used. For the high carbon steel wire, for example, a piano wire prescribed by JIS G3502 can be used.
本發明之基底鋼線係如上述，為鋼線表面具有鍍敷層者。本發明之藉由於基底鋼線表面形成有機皮膜，而獲得有機皮膜之耐剝離性優異之被覆線鋸鋼線。The base steel wire of the present invention is as described above, and has a plating layer on the surface of the steel wire. In the present invention, since the organic film is formed on the surface of the base steel wire, the coated wire saw steel wire excellent in peeling resistance of the organic film is obtained.
上述有機皮膜可使用熱硬化性樹脂或熱可塑性樹脂。該等樹脂中，可適當使用酚樹脂、醯胺系樹脂、醯亞胺系樹脂、聚醯胺醯亞胺、環氧樹脂、聚胺基甲酸酯、甲醛樹脂、ABS樹脂、氯乙烯、聚酯等。尤其可適當使用聚胺基甲酸酯或聚醯胺醯亞胺。As the above organic film, a thermosetting resin or a thermoplastic resin can be used. Among these resins, a phenol resin, a guanamine resin, a quinone imide resin, a polyamidimide, an epoxy resin, a polyurethane, a formaldehyde resin, an ABS resin, a vinyl chloride, a poly Ester and the like. In particular, a polyurethane or a polyamidoximine can be suitably used.
上述有機皮膜之膜厚較好為例如0.05~15μm。有機皮膜太薄時，切斷時之初期階段有機皮膜被磨耗掉而消失，或者由於有機皮膜自基底鋼線剝離使基底鋼線本身露出。此等情況時，難以安定地切斷工件。據此，有機皮膜之膜厚較好為0.05μm以上，更好為0.5μm以上，又更好為2μm以上。然而，有機皮膜太厚時，被覆線鋸鋼線整體所占之有機皮膜之比例過大，使被覆線鋸鋼線整體之強度下降。因此，於加快鋼線線速以提高生產性時，會有鋼線容易斷線之傾向。據此，有機皮膜之膜厚較好為15μm以下，更好為13μm以下，又更好為10μm以下。The film thickness of the above organic film is preferably, for example, 0.05 to 15 μm. When the organic film is too thin, the organic film is worn away and disappears in the initial stage of cutting, or the base steel wire itself is exposed due to the peeling of the organic film from the base steel wire. In such cases, it is difficult to cut the workpiece in a stable manner. Accordingly, the film thickness of the organic film is preferably 0.05 μm or more, more preferably 0.5 μm or more, and still more preferably 2 μm or more. However, when the organic film is too thick, the proportion of the organic film occupied by the covered wire saw steel wire is too large, and the strength of the coated wire saw steel wire as a whole is lowered. Therefore, when the wire speed of the steel wire is increased to improve the productivity, there is a tendency that the steel wire is easily broken. Accordingly, the film thickness of the organic film is preferably 15 μm or less, more preferably 13 μm or less, and still more preferably 10 μm or less.
被覆線鋸鋼線整體之線徑並無特別限制，但通常為100~300μm左右(較好為100~150μm)。The wire diameter of the covered wire saw steel wire is not particularly limited, but is usually about 100 to 300 μm (preferably 100 to 150 μm).
以下針對本發明之基底鋼線之製造方法，以及藉由於所得之基底鋼線上被覆有機皮膜而製造被覆線鋸鋼線之方法加以說明。Hereinafter, a method for producing a base steel wire according to the present invention, and a method for producing a coated wire saw steel wire by coating an organic film on the obtained base steel wire will be described.
首先，針對本發明之基底鋼線之製造方法加以說明。製造本發明之基底鋼線係使依據一般方法獲得之壓延線材經熱處理後經一次線伸長，再經熱處理後，進行鍍敷後經二次線伸長、脫酯。First, a method of manufacturing the base steel wire of the present invention will be described. The base steel wire system of the present invention is produced. The rolled wire obtained according to the general method is subjected to heat treatment, elongated by a primary line, and after heat treatment, is subjected to plating, and then elongated and de-esterified by a secondary wire.
一次線伸長前之熱處理(鋼絲韌化處理)條件、一次線伸長條件、一次線伸長後之熱處理(鋼絲韌化處理)條件、鍍敷條件並無特別限制，為通常方法即可。The heat treatment (steel wire toughening treatment) conditions before the primary linear elongation, the primary linear elongation conditions, the heat treatment after the primary linear elongation (the steel wire toughening treatment) conditions, and the plating conditions are not particularly limited, and may be a usual method.
鍍敷後之二次線伸長之線伸長速度較好為1~30m/秒。線伸長速度在該範圍之外時，鍍敷層表面之算術平均粗糙度Ra超過0.2μm，故會有有機皮膜之耐剝離性變差傾向。該線伸長速度較好為2~20m/秒，更好為3~18m/秒。The elongation rate of the secondary line after plating is preferably from 1 to 30 m/sec. When the linear elongation rate is outside the range, the arithmetic mean roughness Ra of the surface of the plating layer exceeds 0.2 μm, so that the peeling resistance of the organic film tends to be deteriorated. The elongation rate of the wire is preferably from 2 to 20 m/sec, more preferably from 3 to 18 m/sec.
二次伸線時使用潤滑劑以將鍍敷層表面之算術平均粗糙度Ra抑制在0.2μm以下。潤滑劑較好使用市售之油性或水溶性油之潤滑劑。該潤滑劑之油溫較好為20~70℃。潤滑劑之油溫更好為25~60℃，又更好為30~50℃。A lubricant is used in the secondary stretching to suppress the arithmetic mean roughness Ra of the surface of the plating layer to 0.2 μm or less. The lubricant is preferably a commercially available oily or water-soluble oil lubricant. The oil temperature of the lubricant is preferably from 20 to 70 °C. The oil temperature of the lubricant is preferably from 25 to 60 ° C, and more preferably from 30 to 50 ° C.
二次線伸長必須在形成有機皮膜前進行脫脂，去除潤滑劑。本發明中，推薦充分進行該脫脂。鍍敷層之表面上附著潤滑劑(油)時，如後述實施例所證實，有機皮膜容易剝離。因此，本發明藉由儘可能減低鍍敷層表面上附著之油，可進一步提高有機皮膜之耐剝離性。The secondary line elongation must be degreased before the formation of the organic film to remove the lubricant. In the present invention, it is recommended to sufficiently perform the degreasing. When a lubricant (oil) adheres to the surface of the plating layer, the organic film is easily peeled off as confirmed by the examples described later. Therefore, in the present invention, the peeling resistance of the organic film can be further improved by reducing the oil adhering to the surface of the plating layer as much as possible.
脫脂方法並無特別限制，列舉為以與潤滑劑具有親和性之有機溶劑(例如，丙酮或己酮等)洗淨上述基底鋼線之方法，或在還原性氛圍中加熱之火光燒鈍等。The degreasing method is not particularly limited, and examples thereof include a method of washing the base steel wire with an organic solvent having affinity with a lubricant (for example, acetone or hexanone), or a fire blunt or the like heated in a reducing atmosphere.
脫脂後之上述鍍敷層表面附著之油較好為每1g基底鋼線為70μg以下，更好為60μg以下，又更好為40μg以下。上述鍍敷層之表面附著之油愈少愈好。The oil adhering to the surface of the plating layer after degreasing is preferably 70 μg or less, more preferably 60 μg or less, and still more preferably 40 μg or less per 1 g of the base steel wire. The less the oil adhered to the surface of the above plating layer, the better.
上述鍍敷層之表面附著之油量之測定方法可採用例如測定脫脂前後之基底鋼線質量之方法。或者，採用以溶劑(例如己烷或四氯化碳等)萃取基底鋼線表面所附著之油，使用紅外線分光光度計(IR)或傅立葉轉換紅外線分光光度計(FT-IR)定量萃取物所含油量之方法。As a method of measuring the amount of oil adhering to the surface of the plating layer, for example, a method of measuring the quality of the base steel wire before and after degreasing can be employed. Alternatively, the oil adhered to the surface of the base steel wire is extracted with a solvent (for example, hexane or carbon tetrachloride), and the extract is quantitatively determined by an infrared spectrophotometer (IR) or a Fourier transform infrared spectrophotometer (FT-IR). The method of oil content.
脫脂後之上述鍍敷層表面附著之油量亦可藉由定量脫脂後之上述鍍敷層表面附著之附著物所含碳成分而評價。鍍敷層表面附著之附著物中所含碳成分，每1m基底鋼線較好為15μg以下，更好為13μg以下，又更好為10μg以下。上述鍍敷層表面附著之附著物所含之碳成分量儘可能少愈好。The amount of oil adhering to the surface of the plating layer after degreasing can also be evaluated by quantitatively desorbing the carbon component contained in the adhering matter on the surface of the plating layer after degreasing. The carbon component contained in the deposit adhered on the surface of the plating layer is preferably 15 μg or less, more preferably 13 μg or less, and still more preferably 10 μg or less per 1 m of the base steel wire. The amount of the carbon component contained in the adherend adhering to the surface of the plating layer is as small as possible.
上述鍍敷層表面附著之附著物之碳成分量可藉由例如使用碳硫分析裝置之燃燒紅外線吸光法測定。The amount of the carbon component of the adhering matter adhering to the surface of the plating layer can be measured by, for example, a combustion infrared absorption method using a carbon sulfur analyzer.
本發明之被覆線鋸鋼線係如上述，可藉由於經脫脂獲得之基底鋼線表面被覆有機皮膜而製造。The coated wire saw steel wire of the present invention can be produced by coating the surface of the base steel wire obtained by degreasing with the organic film as described above.

如此獲得之本發明之被覆線鋸鋼線可用以切斷例如金屬或陶磁、矽、水晶、半導體構件、磁性體材料等工件(切片加工)而製造切斷體。The coated wire saw steel wire of the present invention thus obtained can be used to cut a workpiece such as a metal, a ceramic, a crucible, a crystal, a semiconductor member, or a magnetic material (slicing process) to produce a cut body.
以線鋸機進行切斷係一面將含研磨粒之溶液吹送向被覆線鋸鋼線一面進行。其原因為將吹送之溶液中所含之游離研磨粒引導入被覆線鋸鋼線與工件之間，有助於一面磨耗工件一面進行切斷。The cutting system was carried out by a wire saw machine while blowing a solution containing abrasive grains to the coated wire sawing steel wire.

After heat treatment (toughening (LP) by lead wire at 550 ° C), the primary wire was elongated to a diameter of 0.88 mm, and then heat-treated (toughened by lead wire at 550 ° C). Next, a plating layer shown in the following Table 1 was formed, and the secondary wire was elongated to a diameter of 0.132 mm, and then the base steel wire was produced by degreasing.
鍍敷層係以Cu-Zn鍍敷層、Cu鍍敷層、或Zn鍍敷層之任一種形成。Cu-Zn鍍敷層之成分組成為Cu:63質量%，Zn:37質量%，利用電解電鍍形成。Cu鍍敷及Zn鍍敷係藉由電解電鍍形成。形成之鍍敷層種類示於下表1。又，表1之No.1及No.2為未形成鍍敷層之例。The plating layer is formed of any one of a Cu-Zn plating layer, a Cu plating layer, or a Zn plating layer. The composition of the Cu-Zn plating layer was Cu: 63% by mass and Zn: 37% by mass, and was formed by electrolytic plating. Cu plating and Zn plating are formed by electrolytic plating. The types of plating layers formed are shown in Table 1 below. Further, No. 1 and No. 2 of Table 1 are examples in which a plating layer is not formed.

二次線伸長後之脫脂係在丙酮浸漬24小時後，以超音波洗淨後乾燥而進行。The degreasing after the secondary line was stretched was immersed in acetone for 24 hours, and then washed with ultrasonic waves and dried.
以雷射顯微鏡(LASERTECH公司製造之「1LM21W」，倍率：1000倍)觀察基底鋼線之表面，藉此測定表面之算術平均粗糙度Ra。粗糙度Ra係在基底鋼線之中央部份以縱方向50μm×長度方向100μm之面測定。算術平均粗糙度Ra之測定結果示於下表1。The surface of the base steel wire was observed with a laser microscope ("LM24W" manufactured by LASERTECH, magnification: 1000 times), thereby measuring the arithmetic mean roughness Ra of the surface. The roughness Ra was measured at a central portion of the base steel wire in a longitudinal direction of 50 μm × a longitudinal direction of 100 μm. The measurement results of the arithmetic mean roughness Ra are shown in Table 1 below.
又，以傅立葉轉換紅外線分光光度計(FT-IR)定量分析基底鋼線表面附著之油量。定量分析具體而言係以如下順序進行。首先，將基底鋼線切成長度1~2cm，測定其質量後放入容量100ml之燒杯中。於其中注入30ml之四氯化碳以超音波萃取後，以四氯化碳固定容量成50ml，藉此調整樣品。Further, the amount of oil adhering to the surface of the base steel wire was quantitatively analyzed by a Fourier transform infrared spectrophotometer (FT-IR). The quantitative analysis is specifically carried out in the following order. First, the base steel wire was cut into a length of 1 to 2 cm, and the mass was measured and placed in a beaker having a capacity of 100 ml. After injecting 30 ml of carbon tetrachloride into the mixture, ultrasonic wave extraction was carried out, and the volume was fixed to 50 ml with carbon tetrachloride, thereby adjusting the sample.
經固定容量之樣品放入光路長100ml之石英盒中，使用FT-IR(日本電子股份有限公司製造，「JIR-5500型」)，以透射法，分解能4cm-1 ，累積次數100次測定。空白試驗僅以四氯化碳進行測定，由上述樣品之測定結果減掉空白試驗之測定結果，基於伸甲基之C-H鍵基於2927cm-1 部分之吸光度，進行樣品中所含油量之定量。油量之定量係針對二次線伸長時使用之潤滑劑預先作成之校正線進行。油量之定量結果換算成每1g之基底鋼線之結果示於下表1。再者，使用水溶性油作為潤滑劑時，並未測定油量。The sample having a fixed capacity was placed in a quartz cell having an optical path length of 100 ml, and FT-IR ("JIR-5500" manufactured by JEOL Ltd.) was used, and the decomposition energy was 4 cm -1 by the transmission method, and the cumulative number of times was measured 100 times. The blank test was carried out only with carbon tetrachloride, and the measurement result of the above sample was subtracted from the measurement result of the blank test, and the amount of oil contained in the sample was quantified based on the absorbance of the CH bond of methyl group based on the absorbance of the portion of 2927 cm -1 . The amount of oil is determined by a calibration line prepared in advance for the lubricant used for the elongation of the secondary wire. The results of the quantitative calculation of the amount of oil converted into the base steel wire per 1 g are shown in Table 1 below. Further, when a water-soluble oil was used as the lubricant, the amount of oil was not measured.
另外，所得基底鋼線中之表面附著物之碳成分係以燃燒紅外線吸收法，以碳硫分析裝置(堀場製作所製造「EMIA U510」)測定。測定具體而言係以如下順序進行。首先，將基底鋼線切斷成長度80cm，測定其質量後放入磁性缽中。將其加熱至燃燒溫度600℃，測定表面附著物之碳成分。碳成分之測定結果換算成每1m之基底鋼線所得之結果示於下表1。Further, the carbon component of the surface adhering matter in the obtained base steel wire was measured by a combustion infrared absorption method and a carbon sulfur analyzer ("EMIA U510" manufactured by Horiba, Ltd.). The measurement is specifically carried out in the following order. First, the base steel wire was cut into a length of 80 cm, and the mass was measured and placed in a magnetic crucible. This was heated to a combustion temperature of 600 ° C, and the carbon component of the surface adhering matter was measured. The results obtained by converting the measurement results of the carbon component into the base steel wire per 1 m are shown in Table 1 below.
接著，以各種厚度將由聚胺基甲酸酯或聚醯胺醯亞胺所構成之有機皮膜被覆於經脫脂獲得之基底鋼線表面，製造被覆線鋸鋼線。具體而言，被覆線鋸鋼線係將清漆分成4~10次塗佈於上述基底鋼線之表面，使之加熱並硬化而製備。有機皮膜之材料及厚度示於下表1。Next, an organic film composed of polyurethane or polyamidolimide was coated on the surface of the base steel wire obtained by degreasing at various thicknesses to produce a coated wire saw steel wire. Specifically, the coated wire saw steel wire is prepared by applying a varnish to the surface of the base steel wire 4 to 10 times, heating it, and hardening it. The material and thickness of the organic film are shown in Table 1 below.
下表1所示之No.1~8為使用JIS C2351所規定之聚胺基甲酸酯線用清漆「W143」(東特塗料股份有限公司製造，漆包線用漆料「TPU F1(商品名)」)，經燒成後之塗膜組成為聚胺基甲酸酯)。No. 1 to 8 shown in the following Table 1 is a varnish "W143" for the polyurethane line stipulated in JIS C2351 (manufactured by Tote Paint Co., Ltd., paint for enameled wire "TPU F1 (trade name)" ”), the composition of the coating film after firing is a polyurethane).
下表1所示之No.9、10係使用聚醯胺醯亞胺線用清漆(東特塗料股份有限公司製造，漆包線用清漆「Neoheat AI-00C(商品名)」，經燒成後之塗膜組成為聚醯胺醯亞胺)。The No.9 and 10 shown in the following Table 1 are made of varnish for polyamidoximine wire (manufactured by Tote Paint Co., Ltd., varnish for enamel wire "Neoheat AI-00C (trade name)", after firing The composition of the coating film is polyamidoximine).
又，觀察所得被覆線鋸鋼線之剖面之結果，鍍敷層之厚度為0.3μm。Further, as a result of observing the cross section of the obtained wire saw wire, the thickness of the plating layer was 0.3 μm.
接著，針對所得被覆線鋸鋼線進行絞合試驗，藉此評價有機皮膜之耐剝離性。絞合試驗係自被覆線鋸鋼線採取長度200mm之試驗片，使夾具間距離(標點間距離)成為50mm，藉由施加降伏點以下之張力而進行。測定有機皮膜剝離前之絞合次數(次)，且以掃描電子顯微鏡(SEM，觀察倍率：20倍)觀察有機皮膜之剝離狀態。使用使試驗片之直徑經基準化之以下式計算出之絞合值(100D換算)，評價有機皮膜之耐剝離性。評價基準如下，評價結果示於下表1。Next, the obtained coated wire saw steel wire was subjected to a stranding test to evaluate the peeling resistance of the organic film. In the stranding test, a test piece having a length of 200 mm was taken from the coated wire saw steel wire so that the distance between the jigs (distance between the punctuation marks) was 50 mm, and the tension was applied by applying a tension below the relief point. The number of twists before the peeling of the organic film was measured (times), and the peeling state of the organic film was observed by a scanning electron microscope (SEM, observation magnification: 20 times). The peeling resistance of the organic film was evaluated by using the stranding value (100 D conversion) calculated by the following formula which normalized the diameter of the test piece. The evaluation criteria are as follows, and the evaluation results are shown in Table 1 below.
絞合值(100D換算)=絞合次數×(試驗片之直徑/夾具間距離)×100Stranding value (100D conversion) = number of stranding × (diameter of test piece / distance between clamps) × 100
○(合格)：絞合值為25次以上○ (qualified): the stranding value is 25 or more
△(合格)：絞合值為20次以上，未達25次△ (qualified): the stranding value is more than 20 times, less than 25 times
×(不合格)：絞合值未達20次× (failed): the stranding value is less than 20 times
由表1可知如下。No.1、2為使用未滿足本發明所規定之要件之基底鋼線所製造之被覆線鋸鋼線之例，由於在鋼線與有機皮膜間未形成鍍敷層，故有機皮膜容易剝離。Table 1 shows the following. No. 1 and 2 are examples of a coated wire saw steel wire produced by using a base steel wire which does not satisfy the requirements of the present invention. Since a plating layer is not formed between the steel wire and the organic film, the organic film is easily peeled off.
另一方面，No.3~10為使用滿足本發明所規定要件之基底鋼線製造被覆線鋸鋼線之例，由於在鋼線與有機皮膜間形成鍍敷層，故可知可提高有機皮膜之耐剝離性。又，針對No.3~10，比較基底鋼線表面之算術平均粗糙度Ra時，Ra越小則絞合值越大，可知有進一步改善有機皮膜之耐剝離性之傾向。又，針對No.3~10，基底鋼線表面附著之油量每1g之基底鋼線為70μg以下，表面附著物之碳成分每1m之基底鋼線為15μg以下。On the other hand, No. 3 to 10 are examples in which a coated wire saw steel wire is produced using a base steel wire which satisfies the requirements of the present invention, and since a plating layer is formed between the steel wire and the organic film, it is known that the organic film can be improved. Peel resistance. Further, in the case of No. 3 to 10, when the arithmetic mean roughness Ra of the surface of the base steel wire was compared, the smaller the Ra, the larger the stranding value, and it was found that the peeling resistance of the organic film was further improved. Further, in Nos. 3 to 10, the amount of oil adhering to the surface of the base steel wire is 70 μg or less per 1 g of the base steel wire, and the carbon content of the surface deposit is 15 μg or less per 1 m of the base steel wire.
又，No.2中使用之基底鋼線二次線伸長成直徑0.132mm時之線伸長速度小如1.70m/秒。因此，No.2所用之基底鋼線之表面算術平均粗糙度Ra雖為0.2μm以下，但由於鋼線與有機皮膜間未形成鍍敷層，故無法改善有機皮膜之耐剝離性。Further, when the secondary wire of the base steel wire used in No. 2 was elongated to a diameter of 0.132 mm, the linear elongation speed was as small as 1.70 m/sec. Therefore, although the surface arithmetic mean roughness Ra of the base steel wire used in No. 2 is 0.2 μm or less, since the plating layer is not formed between the steel wire and the organic film, the peeling resistance of the organic film cannot be improved.
與上述實驗例1同樣，使壓延線材一次線伸長至直徑0.88mm後，再經熱處理(在550℃下經鉛絲線韌化處理(LP))後形成Cu鍍敷層後，二次線伸長至直徑0.132mm，接著藉由脫脂，製造基底鋼線。In the same manner as in the above Experimental Example 1, the calendered wire was stretched to a diameter of 0.88 mm, and then subjected to heat treatment (after 550 ° C toughening treatment (LP) by a lead wire) to form a Cu plating layer, and then the secondary wire was elongated to A diameter of 0.132 mm was followed by degreasing to produce a base steel wire.
二次線伸長成直徑0.132mm時，使用油性潤滑劑(共榮社化學股份有限公司製造之「METELSHIN(商品名)」)。潤滑劑之油溫為25℃，線伸長速度為3.30m/秒。When the secondary wire is elongated to a diameter of 0.132 mm, an oil-based lubricant ("METELSHIN (trade name)" manufactured by Kyoeisha Chemical Co., Ltd.) is used. The oil temperature of the lubricant was 25 ° C and the linear elongation rate was 3.30 m / sec.

The results obtained by converting the quantitative results of the oil amount into 1 g of the base steel wire are shown in Table 2 below.
又，基底鋼線之表面附著物之碳成分係以與上述實驗例1相同之條件，利用燃燒紅外線吸收法，以碳硫分析裝置測定。碳成分量之測定結果換算成每1m之基底鋼線所得之結果示於下表2。Further, the carbon component of the surface adhering matter of the base steel wire was measured by a carbon-sulfur analyzer by a combustion infrared absorption method under the same conditions as in the above Experimental Example 1.

Further, as a result of observing the cross section of the covered wire saw steel wire, the thickness of the plating layer was 0.3 μm.

The evaluation results are shown in Table 2 below.
No.21~23為使用滿足本發明規定之要件之基底鋼線製造之被覆線鋸鋼線之例，由於在鋼線與有機皮膜之間形成鍍敷層，故提高有機皮膜之耐剝離性。由表2，可知基底鋼線表面附著之油量愈低絞合值愈大，有進一步改善有機皮膜之耐剝離性之傾向。No. 21 to 23 are examples of coated wire saw steel wires manufactured using a base steel wire satisfying the requirements of the present invention. Since a plating layer is formed between the steel wire and the organic film, the peeling resistance of the organic film is improved. From Table 2, it is understood that the lower the amount of oil adhering to the surface of the base steel wire, the larger the stranding value, and the tendency to further improve the peeling resistance of the organic film.

To a diameter of 0.132 mm, a base steel wire was then produced by degreasing.
