<P>PROBLEM TO BE SOLVED: To improve the fatigue resistance of a sliding member which has an overlay layer made of an Sn alloy formed on a sliding alloy through an intermediate layer made of Ni or a Ni alloy, without impairing the conformability of the overlay layer. <P>SOLUTION: The overlay layer of the sliding member includes Cu, and a Sn-Cu compound which is formed so as to project into itself from the intermediate layer by heat treatment. Because the Sn-Cu compound has high strength, the fatigue resistance is improved. In addition, because the surface part of the overlay layer has a matrix abundant in Sn, the sliding member acquires the improved conformability and superior non-seizing properties. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
