Description
본 발명은 경질층과 인성이 우수한 금속 Ti층과의 3층이상의 교호 적층으로 되고, 우수한 내마모성 표면피복층을 고속도강 기본 표면에 강한 결합력으로 형성하여서 된 표면 피복 고속도강 부재에 관한 것이다.The present invention relates to a surface-coated high-speed steel member formed by alternating three or more layers of a hard layer and a metal Ti layer having excellent toughness, and forming an excellent wear-resistant surface coating layer with a strong bonding force on a high-speed steel base surface.
종래 고속도강 기본체 표면에 탄화티탄(이하 TiC로 표시함), 질화티탄(이하 TiN로 표시함), 탄질화티탄(이하 TiCN로 표시함), 탄질산화티탄(이하 TiCNO로 표시함) 및 탄산화티탄(이하 TiCO로 표시함)으로 되는 군(이하 이들을 총칭하여 Ti화합물이라 함)중의 1종의 단층 또는 2종이상의 복층으로 되는 층두께 0.5-10μm의 경질피복층을 형성한 표면피복 고속도강부재가 절삭공구로서 사용되고 있다.Titanium carbide (hereinafter referred to as TiC), titanium nitride (hereinafter referred to as TiN), titanium carbonitride (hereinafter referred to as TiCN), titanium carbonitride (hereinafter referred to as TiCNO) and titanium carbonate on the surface of the conventional high speed steel base The surface-coated high-speed steel member which forms the hard coating layer of 0.5-10 micrometers of the thickness which consists of one type | mold single layer or two or more types of layers of the group (henceforth collectively called Ti compound) consists of a cutting tool. It is used as.
일반적으로 상기 종래의 표면피복 고속도강부재의 결질피복층은 고속도강기체에 행한 열처리 효과가 없어지지 않도록 하기 위하여 고속도강 기체의 소둔온도 이하의 비교적 저온도에서 콩상의 물리 증착법(프라즈마 화학증착법을 포함)에 의한 저온에서의 경질 피복층 형성의 경우에는 기체상에 경질피복층을 두껍게 형성시켜도 기대한 만치의 내마모성 향상이 되지 않는 실정이다.In general, the inert coating layer of the conventional surface coating high speed steel member is formed at a low temperature by soybean physical vapor deposition (including plasma chemical vapor deposition) at a relatively low temperature below the annealing temperature of the high speed steel so that the heat treatment effect on the high speed steel is not lost. In the case of forming the hard coating layer, even if the hard coating layer is formed thick on the substrate, the expected wear resistance is not improved.
이 원인에는 여러가지 설이 있으나, 물리증착법에 의한 저온에서의 처리는 경질피복층이 주상 결정구조로 되기 쉽고, 따라서 경질피복층이 두께를 두텁게 하면 이것은 길게 늘어난 주상조직으로 되어 취약성이 현저히 증대하며, 그리고 주상조직에서는 주상결정간의 결합력이 약한 것과 상합하여 단순히 층두께를 두껍게 하더라고 소망의 내마모성의 향상을 얻을 수 없는 것으로 생각되고 있다.There are various reasons for this, but the treatment at low temperature by physical vapor deposition tends to make the hard coat layer into columnar crystal structure, so when the hard coat layer becomes thick, it becomes a long columnar tissue, and the fragility is significantly increased. It is thought that the desired wear resistance improvement cannot be obtained even if the thickness of the layer is simply increased in accordance with the weak bonding strength between the columnar crystals.
여기서 본 발명자들은 상기한 관점으로 부터 저온에서의 처리가 가능한 물리증착법(프라즈마 화학증착법을 포함)을 이용하여 기체와의 밀착성이 우수하고 내마모성에도 우수한 경질피복층을 고속도강기체의 표면에 형성하고자 연구를 행한 결과 1층의 결질층의 두께를 될수록 엷게하여 주상결정구조의 발달을 억제함과 동시에 이 경질층을 2층 이상 형성하며, 한편 적어도 전기 경질층간에는 기체 표면 및 경질층과의 밀착성이 우수하고 인성이 풍부한 금속 Ti층을 개재시켜 3층 이상의 복층구조로 하고 전체적으로 소정의 층두께를 가지는 표면피복층으로 하면 전기 금속 Ti층이 가지는 우수한 인성 및 층간 결합력에 의하여 예로서 절삭시에 작용하는 강한 응력에 대한 쿳숀효과를 발휘하고 이결과 가혹한 조건하에서의 습찰마모에도 경질층이 "칩핑(chipping)함이 없고, 각층의 층두께는 엷으나 2층이상의 경질층에 의하여 우수한 내마모성이 확보되도록 된다는 것을 알게되었다.From the above point of view, the present inventors conducted a study to form a hard coat layer on the surface of high-speed steel by using physical vapor deposition (including plasma chemical vapor deposition) that can be processed at low temperature, and excellent adhesion to gas and excellent wear resistance. As a result, the thickness of one layer of thin film becomes thinner to suppress the development of columnar crystal structure, and at least two layers of this hard layer are formed, while at least between the hard layers, the adhesion between the gas surface and the hard layer is excellent and the toughness is excellent. If the surface coating layer has a multi-layered structure having three or more layers through this rich metal Ti layer and has a predetermined layer thickness as a whole, the excellent toughness and interlayer bonding strength of the electrometal Ti layer, for example, prevent the strong stress acting upon cutting. As a result of the quenching effect, the hard layer is also subjected to chipping (c It was found that there is no hipping, and that the layer thickness of each layer is thin but excellent wear resistance is ensured by hard layers of two or more layers.
따라서, 본 발명은 상기에서 얻은 지식에 기초하여 된 것으로 고속도강치체의 표면에 표면피복층을 형성하여서 되는 표면피복고속도강부재에 있어서, 전기 표면피복층을 Ti화합물로서 된 층두께 0.2-3μm의 경질층 2층 이상과 적어도 전기 경질층간에 개재시킨 금속 Ti로 되는 층두께 0.1-1μm의 금속층과의 3층이상의 교호 적층으로 구성하고 전체 층두께를 2-15μm로 함을 특징으로 하는 것이다.Therefore, the present invention is based on the above-mentioned knowledge, and in the surface-coated high-speed steel member in which the surface-coated layer is formed on the surface of the high-speed steel body, the hard layer 2 having a layer thickness of 0.2-3 μm in which the electrical surface-coated layer is a Ti compound. It consists of alternating lamination | stacking of three or more layers with the metal layer of the layer thickness 0.1-1 micrometer which consists of a metal Ti interposed between more than a layer and at least an electric hard layer, and makes the total layer thickness 2-15 micrometers.
또한 본 발명에 표면 피복 고속도강부재에 있어서, 표면피복층이 우수한 내마모성을 가지는 것을 경질층을 물리증착법에 의하여 형성함에 있어서는 금속성분과 반응가스선분과를 기체프라즈마중 또는 프라즈마의 작용에 의하여 기체표면상에서 반응시키는 것이 행하여지나 이경우 금속 Ti층이면 분위기나 반응의 불균일성 및 반응온도의 영향등으로 인하여, 또는 분위기가스나 반응가스의 분자나 이온등의 침입에 의하여, 여분으로 또는 편재적으로 들어있는 질소, 산소 혹은 탄소등이 이 금속 Ti층에 흡수되어 안정화되고 이 결과로 결질층내의 결정결합력이 강화되도록 됨과 동시에 피복층 자체가 우수한 내마모성 및 내칩핑성을 가지게 되는 것으로 생각된다.In the present invention, in the surface-coated high-speed steel member, in the formation of the hard layer by physical vapor deposition, the surface-coated layer has excellent abrasion resistance, and the metal component and the reactant gas line are reacted on the gas surface by the action of gas plasma or plasma. In this case, in the case of the metal Ti layer, nitrogen, oxygen, or excess contained in the atmosphere or reaction due to the influence of the reaction temperature and reaction temperature, or by the invasion of molecules or ions of the atmosphere gas or the reaction gas, or It is thought that carbon and the like are absorbed and stabilized in the metal Ti layer, and as a result, the crystal bonding force in the layer is enhanced, and the coating layer itself has excellent wear resistance and chipping resistance.
또한 본 발명의 표면피복 고속도강부재에 있어서의 경질층, 금속 Ti층 및 피복층 전체의 층두께를 각각 상기한 바와 같이 제한한 이유를 이하 설명한다.The reason why the thicknesses of the hard layer, the metal Ti layer, and the entire coating layer in the surface-coated high-speed steel member of the present invention are respectively limited as described above will be described below.
(a) 결질층(a) stratum corneum
그 두께가 0.2μm미만에서는 소망의 우수한 내마모성을 확보할 수 없고, 한편 3μm를 초과하면 주상구조의 발달이 나타나 경질층 자체의 강도를 저하시키게 되므로 두께를 0.2-3μm로 정한다.If the thickness is less than 0.2 μm, the desired excellent wear resistance cannot be secured. On the other hand, if the thickness exceeds 3 μm, the columnar structure will develop and the strength of the hard layer itself will be reduced. Therefore, the thickness is set to 0.2-3 μm.
(b) 금속 Ti층(b) metal Ti layer
이 층두께가 0.1μm미만에서는 경질층 자체의 강도 및 경질층을 구성하는 결정상호의 결합력을 확보할 수 없을 뿐 아니라 결질층 및 기체표면과의 사이에 견고한 결합력을 확보할 수 없고, 더우기 쿳숀효과가 부족하여 소망의 내칩핑성을 얻을 수 없으며, 한편 1μm를 초과한 두께로 되면 피복층 자체의 내마모성이 저하되게 되므로 층두께를 0.1-1μm로 정한다.When the layer thickness is less than 0.1 μm, not only the strength of the hard layer itself and the bonding strength of the crystal layers constituting the hard layer can be secured, but also the firm bonding force between the layer and the gas surface cannot be secured. Insufficient chipping resistance can not be obtained. On the other hand, if the thickness exceeds 1 μm, the wear resistance of the coating layer itself is reduced, so that the layer thickness is set to 0.1-1 μm.
(c) 피복층(c) coating layer
소망의 내마모성 및 내칩핑성을 얻기 위해서는 최저 2μm의 층두께가 필요하난 15μm를 초과하면 피복층자체가 취약화하게 되므로 피복층 전체의 두께를 2-15μm로 정한다.In order to obtain the desired wear resistance and chipping resistance, a minimum thickness of 2 μm is required. However, if the thickness exceeds 15 μm, the coating layer itself becomes weak, so the thickness of the entire coating layer is set to 2-15 μm.
또한 본 발명의 표면 피복 고속도강부재에 있어서의 피복층은 통상의 물릴증착법이나 저온 프라즈마를 이용한 화학증착법등의 방법에 의하여 고속도강의 소둔온도 이하의 반응온도에서 실시하므로서 형성될 수 있으며, 더우기 이 경우 경질층을 구성하는 층은 조성적으로 연속하여 변화하여도 좋으며, 경질층과 금속 Ti층과의 교호적중의 형성은 보다 견고한 상호접합 강도를 확실하게 하기 위하여 동일 장치내에서의 연속적 형성이 소망스럽다.In addition, the coating layer in the surface-coated high-speed steel member of the present invention can be formed by carrying out at a reaction temperature below the annealing temperature of the high-speed steel by a method such as a conventional molybdenum deposition method or a chemical vapor deposition method using a low-temperature plasma, moreover, in this case a hard layer The layers constituting the layer may be compositionally and continuously changed, and the formation of alternating hits between the hard layer and the metal Ti layer is desired for continuous formation in the same apparatus in order to ensure a more firm interconnect strength.
다음으로 본 발명의 표면피복 고속도강부재를 실시예에 의하여 비교예와 대비설명한다.Next, the surface-coated high-speed steel member of the present invention will be described in comparison with the comparative example.
[실시예 1]Example 1

다음으로 진공실내에 Ti보지부를 설치하고 이 Ti보지부의 Ti에 전기 빔을 쪼이고 증발하는 Ti와 도입가스를 프라즈마중에 통과시키는 방식의 이온프레이딩 장치를 사용하고 이것에 우선 Ar을 도입하여 전기 팁의 표면을 프라즈마 엣칭을 하여 세척하고, 다음으로 Ar을 N2+CH4+Ar의 혼합가스로 바꾸어 도입하여 가열온도 450℃에서 반응시켜 TiCN로 되는 층두께 4μm이 경질층을 형성하였다.(이결과 얻은 표면피복 트로우여웨이팁(폐기형팁)을 이하 비교팁이라 한다)Next, a Ti holding part is installed in the vacuum chamber, and an ion framing device is used in which the Ti holding part is irradiated with an electric beam, and the evaporating Ti and the introduced gas are passed through the plasma. The surface was washed by plasma etching, and then Ar was changed into a mixed gas of N 2 + CH 4 + Ar and reacted at a heating temperature of 450 ° C. to form a hard layer having a thickness of 4 μm of TiCN. The obtained surface-covered trough-away tip (closed tip) is referred to as a comparative tip below)
한편 상기 TiCN로 된 경질층의 층두께를 1μm로 한 이외는 상기 비교 피복팁의 제조조건과 동일조건으로 피복팁을 제조한 후 다시 전기 경질층의 위에 도입가스를 Ar으로 바뀐 상태에서 층두께 0.5m의 금속 Ti층을 형성하고 계속하여 동일조건에서 N2+CH4+Ar의 혼합가스와 Ar의 반복도입에 의하여 층두께가 1μm의 TiCN로 되는 경질층 2층과 층두께 0.5μm의 금속 Ti층 1층, 즉 전체로서 5층의 교호 적층으로 되고 전체층 두께가 4μm의 표면 피복층을 형성하므로서 본 발명 피복 트로우어웨이 팁(이하 본 발명 피복팁이라 함)을 제조하였다.Meanwhile, except that the thickness of the hard layer of TiCN was 1 μm, the coating tip was manufactured under the same conditions as those of the comparative coating tip, and the thickness of the introduction gas was changed to Ar on the electrically hard layer. m metal Ti layer was formed, and then, under the same conditions, two hard layers having a thickness of 1 μm TiCN and a layer thickness of 0.5 μm metal Ti were repeatedly formed by repeated introduction of N 2 + CH 4 + Ar mixed gas and Ar. The present invention covered flyaway tip (hereinafter referred to as the present invention coating tip) was prepared by forming an alternating stack of 5 layers as a whole, namely 5 layers, and forming a surface coating layer having a total thickness of 4 μm.
다음으로 이 결과 얻은 본 발명 피복팁, 비교피복 팁 및 절삭공구용 초경질 합금주재로서 준비한 금소 Ti층 및 TiCN층이 없는 상기 트로우어에이팁(이하 무피복팁이라 함)에 대하여 JIS, N11R-44형 콜다를 사용하여, 피삭제 S45C(경도 HD190)의 환봉, 절삭속도 20m/min, 송출 0.1mm/rev절삭유 사용의 조건으로 외경절삭시험을 행하고 전기 각 팁의 도면마모가 0.3mm에 달하기까지의 절삭시간을 측정함과 동시에 표면피복층의 마모상태를 관찰하였다. 그 결과를 제 1표에 표시한다.Next, with respect to the above-mentioned drawer tip (hereinafter referred to as a non-coated tip) without a metallic Ti layer and a TiCN layer prepared as a coating tip, a comparative coating tip, and an ultrahard alloy base material for cutting tools obtained as a result, Using a 44-inch collada, the outer diameter cutting test was performed under conditions of round bar of S45C (hardness H D 190), cutting speed 20m / min, and 0.1mm / rev cutting oil. The cutting time to reach was measured and the wear state of the surface coating layer was observed. The results are shown in the first table.
제 1표에서 보는 바와 같이 본 발명 팁에서는 이상 마모가 전혀 볼 수 없고 비교피복팁의 3배, 무피복팁의 4.5배의 대단히 긴 절삭시간을 가지며, 우수한 절삭가능을 발휘함이 명백히 알 수 있다.As shown in Table 1, it can be clearly seen that the tip of the present invention shows no abnormal wear, an extremely long cutting time of 3 times that of the non-coated tip and 4.5 times that of the uncoated tip, and excellent cutting performance. .
[실시예 2]Example 2
고속도강기체로서 실시예 1에서와 동일한 트로우어에이팁을 사용 이들의 표면에 실시예 1에 적용한 이온 프레팅장치, 진공용기내에 장입한 Ti제 타겔을 소정 분위기중에서 스핏터링하는 스핏티링 장치(sputtering apparatiis) 및 반응용기내에서 발생시킨 프라즈마중에 혼합가스를 유입시켜 화학반응을 행케하고, 화학증착하는 프라즈마 화학증착장치의 각각 사용으로 제 2표에 표시한 층두께의 Ti층 및 경질피복층을 형성하므로서 본 발명 피복팁 a-b 및 비교 피복팁 a-c를 각기 제조하였다.The same high shear steel tip as in Example 1 was used. The ion fritting apparatus applied to Example 1 on the surface thereof, and a spiting apparatus for sputtering a Ti-gel made in a vacuum vessel in a predetermined atmosphere (sputtering apparatiis) ) And the mixed gas is introduced into the plasma generated in the reaction vessel to perform a chemical reaction, and by using a plasma chemical vapor deposition apparatus for chemical vapor deposition, the Ti layer and the hard coating layer of the layer thicknesses shown in Table 2 are formed. Inventive coating tips ab and comparative coating tips ac were prepared respectively.
또한 비교피복팁 a는 금속 Ti층의 형성이 없고, TiCN로 되는 경질층 1층으로 피복층이 구성된 것이며, 비교피복팁 b는 제2층인 금속 Ti층의 층두께가 본 발명 범위보다 높은 쪽으로 벗어난 피복층을 구성한 것이며, 다시 비교피복팁 c는 제2층인 TiC로 되는 경질층의 층두께가 본 발명 범위로 부터 높은쪽으로 벗어난 피복층으로 구성된 것이다.In addition, the comparative coating tip a is a coating layer composed of one hard layer made of TiCN without forming a metal Ti layer, and the comparative coating tip b is a coating layer in which the layer thickness of the metal Ti layer as the second layer deviates from the range higher than the scope of the present invention. The comparative coating tip c is composed of a coating layer in which the layer thickness of the hard layer of TiC, which is the second layer, is out of the range of the present invention.
상기 본 발명 피복팁 a-f 및 비교피복 팁 a-c에 대하여 실시예 1에서와 같은 조건으로 외경절삭시험을 행하고 팁의 도면마모가 0.3mm에 도달하기까지의 절삭시간을 측정함과 동시에 피복층의 마모상태를 관찰하고 제2표에 병합표시하였다.The outer diameter cutting test was carried out under the same conditions as in Example 1 for the coating tip af and the comparative coating tip ac of the present invention, and the cutting time until the drawing wear of the tip reached 0.3 mm was measured. Observed and merged in the second table.
[제 2 표][Table 2]
제2표에 표시된 결과로부터 비교 피복팁 a-c에서 보는 바와같이 금속 Ti층의 형성이 없거나 또는 금속 Ti층의 형성이 있어도 2층의 두께가 그 두께가 너무 두꺼워지는 등의 경우에도 절삭시간은 극히 짧아지던가 하며, 표면피복층이 이상 마모하거나 또는 극심한 칩핑마모에 의하여 절삭마감면의 약화를 초래하여 절삭중지에 이루게 됨은 명백하다 이에 대하여 본 발명 피복팁 a-f는 모두 긴 절삭 수명을 가지고 표면피복층을 마모상태도 정상적이었다.As shown in the comparison coating tip ac from the results shown in Table 2, the cutting time is extremely short even in the case where there is no formation of the metal Ti layer or the formation of the metal Ti layer, the thickness of the two layers becomes too thick. In addition, it is evident that the surface coating layer is abnormally worn or the cutting finish is caused by severe chipping wear, resulting in the cutting stop. It was normal.
[실시예 3]Example 3

제3표에 표시한 결과로부터 명백한 바와같이 본 발명 팁 A-C는 표면피복층이 금속 Ti층과 TiCN의 경질층과의 2층으로 되고 경질층의 층두께가 본 발명범위보다 높은 쪽으로 벗어난 비교피복팁 A에 비하여 현저히 긴 수명시간을 나타내고, 그리고 피복층의 마모상태로 정상한 것이었다.As apparent from the results shown in Table 3, the tip AC of the present invention has a comparative coating tip A in which the surface coating layer is made of two layers of the metal Ti layer and the TiCN hard layer, and the layer thickness of the hard layer is out of the range of the present invention. It showed a significantly longer life time compared with that of the coating layer and was normal in abrasion state of the coating layer.
상술한 바와같이 본 발명의 표면피복고속도강부재는 그 표면 피복층이 금속 Ti층과 경질층과의 3층이상의 교호 적층으로 되고 더우기 이 경질층간에는 이와 강력히 결합하고 그리고 인성이 우수한 금속 Ti층이 기재된 구성으로 되어 있어, 예로서 절삭시에 작용하는 강한 응력에 대하여도 쿳숀효과가 작용하여 피복층이 칩팅을 일으키는 일이 없고 경질층의 적층에 의하여 우수한 내마모성을 확보할 수 있는 등 공업상 유용한 특성을 가지는 것이다.As described above, the surface-coated high-speed steel member of the present invention has a structure in which the surface coating layer is an alternating stack of three or more layers of the metal Ti layer and the hard layer, and furthermore, the metal Ti layer is strongly bonded to the hard layers and has excellent toughness. For example, the cushioning effect is also applied to the strong stress acting during cutting, so that the coating layer does not cause chipping, and excellent wear resistance can be secured by lamination of the hard layer. .
