Sliding member

Abstract

Provided is a sliding member which has high seizure resistance though an overlay layer comprising Ag as the main component is used therein. The sliding member of an embodiment comprises a base and an overlay layer which is disposed on the sliding-side surface of the base and which comprises Ag as the main component and contains Al. The overlay layer comprising Ag as the main component is relatively soft. Due to this, the overlay layer comprising Ag as the main component can ensure high seizure resistance even when the use of Pb is avoided. Furthermore, the overlay layer comprising Ag as the main component has excellent thermal conductivity. Due to this, frictional heat generating at the sliding part rapidly dissipates to the base side.

1 . A sliding member comprising:
 a base; and   an Ag-based overlay layer disposed on a sliding-side surface of the base and comprising Al.   
     
     
         2 . A sliding member comprising:
 a base; and   an Ag-based overlay layer disposed on a sliding-side surface of the base and comprising Al, the overlay layer further comprising at least one of Sn and Zn.   
     
     
         3 . The sliding member according to  claim 1 , wherein the overlay layer comprises 0.1% by mass to 15% by mass of Al. 
     
     
         4 . The sliding member according to  claim 2 , wherein the overlay layer comprises 0.1% by mass to 15% by mass of Al.
