Sliding-Bearing Material

摘要

A sliding-bearing material having enhanced seizure resistance and fatigue resistance. The sliding-bearing material comprises an aluminum bearing alloy whose surface has been treated and a coating layer formed on the aluminum bearing alloy and consisting of from 90 to 55% by weight of a sold lubricant and from 10 to 45% by weight of a polyimide binder. Treatment of the aluminum bearing alloy can be by roughening with alkali etching and pickling, by covering with a chemical conversion film, and/or by drilling.
