PURPOSE:To improve wear-proofness and lubrication performance by dispersing highly rigid material on a cast iron surface on which graphite having self- lubrication is dispersed. CONSTITUTION:Highly rigid wear-proof material 4 are filled in plural concave portions 3 formed by photo etching method on a surface of a cast iron base 1 on which graphite 2 is dispersed. Therefore, graphite 2 having self-lubrication performance and highly rigid water-proof material 4 excellent in wear-proofness are mixed and dispersed on the surface of a slidable contact member. Then, wear-proofness and baking proofness are improved and optimum slidable contact member of high output and high rotation engine is obtained. As the highly rigid wear-proof member is filled in the concave portions formed by photo etching method on the surface of the slidable contact member, better stickness can be obtained and long term use can be made. |
