FILM COMPOSITION FOR SLIDING MEMBER

Title:

FILM COMPOSITION FOR SLIDING MEMBER

Document Type and Number:

WIPO Patent Application WO/2010/126035

Kind Code:

A1

Abstract:

Provided is a film composition for a sliding member, which is for forming a film on the surface of a sliding member and which comprises a binder resin, an abrasion inhibitor, and an appropriate solid lubricant. The abrasion inhibitor is in the form of sheets having an aspect ratio of between 5 and 100 when represented by average grain size/average grain thickness, with the average grain size being 15.0 µm or smaller and the Mohs hardness being 6 or greater. The solid lubricant content may be between 0 and 15 parts by weight per 100 parts by weight of binder resin, and the abrasion inhibitor content may be between 1 and 100 parts by weight per 100 parts by weight of binder resin. The solid lubricant does not have to be included. Preferably the abrasion inhibitor is an alumina abrasion inhibitor. Good lubricity can be maintained by the film composition for a sliding member, even with long-term exposure to harsh abrasion conditions.
