を満足できなくなってきた。However, conventionally known wear-resistant alloys such as iron-based special steels do not necessarily have sufficient corrosion resistance. In addition, conventional alloys generally have the disadvantage that although they have good corrosion resistance, they have poor wear resistance, and when used as linings for cylinders, etc., there have been problems in terms of service life. Moreover, in recent years, resins containing fillers, especially materials such as plastic magnets, rubber magnets, etc., which have strong abrasive effects, and materials such as ceramics have come to be injection molded, making it increasingly difficult for conventional special steels to meet the requirements.

The sign is that it happens.
本発明における肉成層の基地を形成する合金の成分の限
定理由は、以下の通りである。The reasons for limiting the components of the alloy forming the base of the meat layering in the present invention are as follows.
Ｃｒ：Ｎｉ基地中に固溶し、基地の硬さの向上に有効で
あり、またＣと結合して炭化物を形成し、耐摩耗性を高
める。しかし５．０重量％未満では、耐摩耗性及び耐食
性が不十分であり、２０．０重量％を越えると脆性を増
すので、その含有量は５゜０〜２０．０重量％である。Cr: Cr dissolves in the Ni base and is effective in improving the hardness of the base, and also combines with C to form carbide to improve wear resistance. However, if it is less than 5.0% by weight, wear resistance and corrosion resistance will be insufficient, and if it exceeds 20.0% by weight, brittleness will increase, so the content should be 5.0 to 20.0% by weight.
好ましい範囲は１０。The preferred range is 10.
Ｏ〜１８．０重量％である。O~18.0% by weight.
８ ：組織中に高硬度の硼化物を析出させるので合金の

未満では十分な硬さが得られず、溶融点も高く、肉盛後
の肉盛層の収縮代が大きくなるためシリンダの変形や肉
盛層への拍張応力の作用が大きくなる等の問題がある。8: Highly hard boride is precipitated in the structure, which is effective in increasing the hardness of the alloy and improving wear resistance, as well as lowering the melting point. However, 1% by weight
If it is less than that, sufficient hardness cannot be obtained, the melting point is high, and the shrinkage margin of the build-up layer after build-up becomes large, resulting in problems such as cylinder deformation and the effect of tensile stress on the build-up layer. There is.
また５゜０重量％を超えると合金は脆くなり、肉盛層に
冷却時クラックを生じやすくなる。従ってＢの範囲は１
．０〜５．０重量％である。好ましい範囲は２．４〜４
．０重量％である。Moreover, if it exceeds 5.0% by weight, the alloy becomes brittle and cracks are likely to occur in the overlay layer upon cooling. Therefore, the range of B is 1
．． It is 0 to 5.0% by weight. The preferred range is 2.4-4
．． It is 0% by weight.
Ｆｅ：基地の靭性向上に有効であるが、１０゜０重量％
を超えると基地の硬さを低下させ、また耐食性も低下さ
せる。従ってその上限は１０．０重量％である。好まし
い範囲は３〜６重示重量ある。Fe: Effective for improving the toughness of the base, 10°0% by weight
Exceeding this decreases the hardness of the base and also reduces the corrosion resistance. Therefore, its upper limit is 10.0% by weight. The preferred range is 3 to 6 weights.
Ｓｌ：基地の高硬度化に有効で、またＩＫ！酸元木元素
ても必要である。しかし０．５重量％未満の添加では、
十分な硬さが得られず、また５、０重量％を超えると靭
性を悪化させるので、その範囲は０．５〜５．０重量％
である。好ましい範囲は２．０〜４，０重量％である。Sl: Effective for increasing the hardness of the base, and also IK! Acid base wood elements are also required. However, if less than 0.5% by weight is added,
Sufficient hardness cannot be obtained, and if it exceeds 5.0% by weight, toughness deteriorates, so the range is 0.5 to 5.0% by weight.
It is. The preferred range is 2.0 to 4.0% by weight.
Ｃ：Ｎｉに固溶して強度を高めるとともに、合金元素と
結合して炭化物を形成し、耐摩耗性を向上させる。しか
し、１．５０重量％を超えると靭性を低下させるので、
１．５０重量％以下の添加量である。好ましい添加量は
０．４〜１．０重量％である。C: It dissolves in Ni to increase strength, and also combines with alloying elements to form carbides to improve wear resistance. However, if it exceeds 1.50% by weight, the toughness decreases, so
The amount added is 1.50% by weight or less. The preferred amount added is 0.4 to 1.0% by weight.

ともに硼化物を分散させ、耐摩耗性を高める。Ｎｉは不
可避的不純物を除き上記添加元素以外の残部を占める。Note that Ni is a main element constituting the base, and has high corrosion resistance against various atmospheres including fluorine gas atmospheres. It also combines with 8 to precipitate boride, increasing the hardness of the base and dispersing the boride to improve wear resistance. Ni occupies the balance other than the above-mentioned additive elements excluding unavoidable impurities.
本発明では耐摩耗性を向上させるために周期律表の第Ｊ
ＶＡ、ＶＡ、ＶＩＡ族の元素の炭化物の１種又は２種以
上からなる硬質粒子を合金中に分散させる。好ましい炭
化物はＷＣ，ＮｂＣ，Ｔ ｉ Ｃ及びＶＣである。In the present invention, in order to improve wear resistance,
Hard particles made of one or more carbides of elements in groups VA, VA, and VIA are dispersed in the alloy. Preferred carbides are WC, NbC, TiC and VC.
硬質粒子の吊は肉盛層の５〜４０体槓％を占める。硬質
粒子が５体積％未満だと所期の耐摩耗性向上効果が得ら
れず、４０体積％を超えると肉盛層にクラックが生じや
すくなる。The suspension of hard particles accounts for 5 to 40% of the build-up layer. If the amount of hard particles is less than 5% by volume, the desired effect of improving wear resistance cannot be obtained, and if it exceeds 40% by volume, cracks are likely to occur in the built-up layer.
また硬質粒子の粒径は１０〜３００μｍである。Moreover, the particle size of the hard particles is 10 to 300 μm.
粒径が３００μｍを超えると肉盛層にクラックが生じや
すく、１０μｍ未満では肉盛中に基地合金中への固溶が
過度に進行する。またこれらの粒子は母合金との比重の
相違が大きいので、粉体肉盛溶接中における粒子の偏在
を防止するために、粒径が１０〜１００μｍの範囲にあ
るのが好ましい。When the grain size exceeds 300 μm, cracks tend to occur in the build-up layer, and when the grain size is less than 10 μm, solid solution into the base alloy progresses excessively during build-up. Further, since these particles have a large difference in specific gravity from the mother alloy, it is preferable that the particle size is in the range of 10 to 100 μm in order to prevent uneven distribution of particles during powder overlay welding.
肉盛層の厚さは、肉盛後の冷却時の収縮によるクラック
の発生を防止するために、比較的小さくするのが有利で
ある。このため本発明においては肉ｉ層の厚さは加工前
の状態で１０１Ｒ＃１以下が好ましい。It is advantageous for the thickness of the build-up layer to be relatively small in order to prevent the occurrence of cracks due to shrinkage during cooling after build-up. Therefore, in the present invention, the thickness of the meat i layer is preferably 101R#1 or less before processing.
本発明の耐食耐摩耗合金の肉盛層は溶接により形成され
るので、拡散層を介して母材と強固に結合し、耐剥離性
が大きい。Since the built-up layer of the corrosion-resistant and wear-resistant alloy of the present invention is formed by welding, it is firmly bonded to the base material via the diffusion layer and has high peeling resistance.
次に、本発明のシリンダ母材について述べる。Next, the cylinder base material of the present invention will be described.

まであるので塑性変形能も高い。ただし、母材は硬さが
低すぎると母材として必要とされる強さが不足するので
、硬さはＨ８１２１以上程度は必要である。The build-up layer of the present invention is a brittle material that easily cracks. After powder overlay welding is performed on the base material, it is cooled from a high temperature state compared to the base material, so the shrinkage due to cooling becomes larger than the MTFI base material, and cracks are likely to occur due to tensile stress. This tendency becomes more pronounced as the amount of hard particles mixed increases. Therefore, especially when using a build-up material with a large mixed amount of hard particles, it is recommended to use an austenitic material with a large coefficient of thermal expansion (contraction) as the base material for build-up.
This is advantageous from the viewpoint of preventing cracks in the built-up layer. That is, since the base material has a large coefficient of thermal expansion (contraction), it will shrink significantly after the build-up and can follow the amount of shrinkage of the build-up layer. Furthermore, since no transformation occurs during cooling and the austenitic state remains, the plastic deformability is high. However, if the hardness of the base material is too low, the strength required for the base material will be insufficient, so the hardness must be approximately H8121 or higher.
母材はまたＣｒＭＯＭ、Ｎｉ Ｃｒ Ｍｏ鋼又は構
造用炭素鋼等により形成することもできる。The base material can also be formed from CrMOM, Ni Cr Mo steel, structural carbon steel, or the like.

盛厚さは加工前の状態で５ ｔｎｔｎ以下とするのが好
ましい。When using this type of material, it has a smaller coefficient of thermal expansion (shrinkage) and smaller deformability than the austenitic base material, so there is a risk that high tensile stress will occur in the overlay layer and cracks may occur. Therefore, the hard particles in the overlay alloy should be 5 to 20% by volume, and it is necessary to reduce the overall temperature rise due to overlay and reduce the absolute shrinkage, so the overlay thickness should be the same as the state before processing. is preferably 5 tntn or less.

When No. 7 was used, cracks occurred in the overlay layer. Therefore, in the case of base materials of these materials, the hard particles should be at most 20% by volume.
It is better to
