SLIDING MATERIAL, COMPOSITE SINTERED SLIDING MEMBER, AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To improve the wear resistance and to reduce the adhesiveness by the intermetallic compound characteristic of ordered phase for the purpose of improving the seizure resistance and/or wear resistance of a working-machine bearing which undergoes sliding at a low speed under a high bearing pressure and is liable to become out of lubrication, preventing the generation of an abnormal sound and prolonging the greasing interval. SOLUTION: The sliding material is constituted so that it contains >=10 vol.% metallic alloy phase within the compositional range having ordered transformation characteristic. Moreover, the metallic alloy phase is composed of a ferrous alloy phase containing one or more elements among Al, Si, Co and Ni.
