Title:

SLIDING MEMBER AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2014/115457

Kind Code:

A1

Abstract:

This sliding member comprises: a base; a hard chromium plating layer that is formed on the surface of the base and is mainly composed of chromium; and a hard carbon layer that is formed on the hard chromium plating layer and is mainly configured from elemental carbon. The hydrogen concentration of the hard chromium plating layer is 150 ppm by mass or less. This method for producing a sliding member is a production method for the above-described sliding member, wherein the surface of the base, on which the hard chromium plating layer that is mainly composed of chromium is formed, is subjected to a heat treatment at a temperature of 250°C or more so that the hydrogen concentration of the hard chromium plating layer becomes 150 ppm by mass or less, and after that the hard carbon layer that is mainly configured from elemental carbon is formed on the hard chromium plating layer.
