SLIDING MEMBER

摘要

A sliding member which has a substrate and a sliding layer (overlay), wherein the overlay (sliding layer) (4) comprises a base material of a metal selected from among Sn, Pb, Bi, In and Al or an alloy based on the metal and an amorphous carbon as an additive. The overlay (4) is formed by sputtering. Sn, Pb, Bi or In is excellent in non-seizure property due to its low adhesion to a mating material such as Fe. An amorphous carbon improve wear resistance and fatigue resistance due to its high hardness and also improve non-seizure property due to its low friction coefficient. Further, by the addition of an amorphous carbon, the above base material having finer crystal grains is formed, which results in the enhancement of the mechanical strength and further improvement of the wear resistance and fatigue resistance of the overlay (sliding layer).
