METHOD OF MANUFACTURING SLIDING MEMBER AND SLIDING MEMBER

Title:

METHOD OF MANUFACTURING SLIDING MEMBER AND SLIDING MEMBER

Document Type and Number:

WIPO Patent Application WO/2011/074320

Kind Code:

A1

Abstract:

A system (1) of manufacturing a sliding member (2) first forms a sintered alloy layer (4) on a back metal (3) during a primary sintering process. Subsequently, a large number of recessed portions (5) are formed in the surface of the sintered alloy layer (4) by a recessed-portion forming mechanism (14). Next, the sintered alloy layer (4) is subjected to a secondary sintering process after the back metal (3) and the sintered alloy layer (4) are rolled by a reduction roll (15). With this, a sliding member (2) having a large number of recessed portions (5) in the surface thereof is manufactured. Since the recessed portions (5) are formed in the sintered alloy layer (4) after the primary sintering process, work hardening is prevented from occurring at the recessed portions (5) and peripheral portions thereof.
