摘要： PURPOSE:To improve wear resistance and seizing resistance, by forming a sulfurizing layer onto the surface of a thermally sprayed layer of a wear resistant metal subjected to the internal surface of a cylinder liner and into the pores in the layer. CONSTITUTION:The surface of the cylinder liner is thermally sprayed with the wear resistant metal such as carbon steel powder to form the thermally sprayed layer 2 having the fine pores. The sulfurizing layer 4 having a high lubricity is then formed onto the surface of said sprayed layer 2 and into the pores 3 by a sulfurizing treatment in which the layer is heated in a sulfur contg. solution.

摘要： PURPOSE:To lessen a clearance change due to temperature by forming an 'Alumite(R)' layer on a sliding surface of one member of a pair of sliding members, the base metal of which is an aluminum alloy and a Cr plating layer on a sliding surface of the other member. CONSTITUTION:An aluminum alloy which can form an 'Alumite(R)' layer is processed on anode side by an electrolytic bath to obtain an 'Alumite(R)' layer forming member as one member. On the other hand, Cr plating layer is formed on the surface of the other member by electroplating. A difference in thermal expansion coefficient between both aluminum alloys which are base metals of a combination sliding portion is less than 3X10 / deg.C. When the combination sliding member is used in a piston type, a clearance change due to thermal expansion is very little so that stick is not caused.
