くなる。Next, the operation will be described. When the uneven portion 2 is formed on the surface of a material having a relatively low hardness by sandplast, and the high hardness film 3 such as TiC or TiN is further formed on the uneven portion 2, the surface shape of the uneven portion 2 formed by sandplast Is formed into a high hardness film, and the high hardness film has uneven portions.

Good.
化学反応を用いた場合は、第二の材料が第一の材料と化
学的に結合するため、その接合は強力である。When a chemical reaction is used, the bond is strong because the second material chemically bonds with the first material.

生成物を基材上に蒸着させる処理方法である。As an example of the case of chemical reaction, CVD (Chemical Vapor
par Deposition) processing. An example of a physical reaction is PVD (physical Vapar Depositi
on) processing. In the CVD process, the material forming the film is vaporized, and it is made to flow on a heated substrate to deposit the product of a chemical reaction such as hydrolysis, self-decomposition, photolysis, redox, and substitution on the substrate. It is a processing method.
これに対し、PVD処理は、膜とする材料を物理的に基材

た膜とする材料の蒸気圧を上げ基材上に堆積する真空蒸
着法が代表的なものである。On the other hand, the PVD process physically deposits the material to form a film on the base material, and heating in a vacuum raises the vapor pressure of the material to form the vaporized film and deposits it on the base material. The vapor deposition method is typical.

のでもよい。In this high friction sliding material with excellent wear resistance, the relatively low hardness material is high carbon steel such as S45C, S55C, and the relatively high hardness coating is formed by laser irradiation on the high carbon steel. It was hardened with an electron beam. Alternatively, the relatively low hardness material may be cast iron such as FC25 and FCD45, and the relatively high hardness coating may be formed by quenching the cast iron with a laser or an electron beam. Further, the relatively low hardness material is a steel material such as carbon steel or cast iron,
The above-mentioned relatively hard coating is formed on the above steel materials by TiC
Alternatively, TiN may be processed by CVD (Chemical Vapar Deposition).

量の大なる部分と小なる部分が交互に存在するようにな
る。そのため、縞を横ぎるように摺動がおこると摺動時
の抵抗、すなわち、摩擦が大きくなる。In the relatively low hardness material portion, the amount of deformation at the time of contact when sliding with another object becomes large, but in the relatively high hardness material portion, the amount of deformation at the time of contact becomes small. Since the relatively high hardness portions are arranged in a striped pattern, portions having a large amount of deformation and portions having a small amount of deformation are alternately present at the time of contact. Therefore, when sliding occurs so as to cross the stripe, the resistance at the time of sliding, that is, friction increases.
