Filed: 2002-06-14
Abstract: <P>PROBLEM TO BE SOLVED: To improve sliding characteristics, especially wear resistance, and also to improve adhesive strength of a sliding layer in a sliding member having a sliding layer on the sliding surface.  <P>SOLUTION: A plated layer 1a is provided on the surface of a base material 1 made of stainless steel or carbon steel, and metal powder of a copper alloy or the like is sprayed on the surface of the plated layer 1a and sintered to form a porous layer 2.

PBI is more excellent in heat resistance and has higher material strength as compared with those of thermosetting resin (PAI, PI, EP resin), so as to improve the wear resistance and non-seizure performance. Since the sliding layer 3 contains the solid lubricant, a coefficient of friction is lowered so as to improve non-seizure performance. Since the porous layer 2 is impregnated and coated with the sliding layer 3, the adhesive strength is high so that the layers are hardly separated from each other.  <P>COPYRIGHT: (C)2004,JPO
