Abstract
Official abstract text for this publication.
Raw material powder containing metal powder as a main component is molded to form a metal powder molded body ( 3 ′), and the metal powder molded body ( 3 ′) is sintered to form a metal substrate ( 3 ). Further, a lubricating member ( 4 ) is made of an aggregate of graphite particles ( 13 ), and at least a part of a bearing surface ( 11 ) is formed of the fabricating member ( 4 ). The lubricating member ( 4 ) is fitted into the metal powder molded body ( 3 ′). After that, the metal powder molded body ( 3 ′) is sintered, and at this time, the lubricating member ( 4 ) is fixed onto the metal substrate ( 3 ) with a contraction force (F) generated in the metal powder molded body ( 3 ′).
First claim
Opening claim text (preview).
The invention claimed is: 1. A sliding member having a sliding surface that slides with a mating member, comprising: a metal substrate, which is formed by sintering raw material powder containing metal powder as a main component, the metal powder containing copper and iron as main components; and a lubricating member, which is made of a sintered body of coated powder formed by coating graphite powder with copper, wherein at least a part of the sliding surface is formed of the lubricating member, wherein the metal powder of the metal substrate is bonded to each other through copper-tin alloy, wherein the coated powder of the lubricating member is bonded to each other through copper-tin alloy, and wherein the metal powder of the metal substrate and the coated powder of the lubricating member are bonded to each other through copper-tin alloy. 2. The sliding member according to claim 1 , wherein the sliding surface is subjected to sizing.
