Composite material for sliding member having graphite-containing phosphor bronze sintered layer and method of manufacturing the same

摘要

A composite material for a sliding member has a back metal layer and a graphite-containing phosphor bronze sintered layer bonded to the back metal layer. The graphite-containing phosphor bronze sintered layer consists essentially of 0.03 to 1 wt % phosphorus, 7.5 to 16 wt % tin, 1 to 8 wt % graphite and the balance copper, and is constituted by phosphor bronze powder passing through a 200-mesh screen and a graphite powder passing through a 350-mesh screen. Also disclosed is a method of manufacturing the above-mentioned composite material for a sliding member.
