Embodiment Construction

[0015] A detailed description is given below regarding the coating composition for a sliding member according to the present invention. The coating composition for a sliding member according to the present invention is used for the sliding of a coating (coating layer) that forms a dry coating lubricant in order to improve wear resistance, scratch resistance, etc. while reducing the coefficient of friction. Coating composition for components. The basic composition of the coating composition for sliding members includes a binder resin, an inorganic filler as a wear suppressing material, and a solid lubricant as needed. In the following description, the coating composition for a sliding member may be simply referred to as a composition for convenience.

[0016] [Binder Resin] The type of the binder resin is not particularly limited. A known resin used as a binder resin of a coating composition for a sliding member in the related art can be used. As described later, this is bec...

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 [mu]m 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.

Description

technical field [0001] The present invention relates to a coating composition for a sliding member, which is used for forming a coating layer of a dry-coated lubricant in order to improve wear resistance, anti-burning properties, and the like while reducing the coefficient of friction. Background technique [0002] Examples of sliding members in automobiles include bearings for engines, pistons of engines, piston rings, and swash plates of swash plate compressors. For example, between a piston and a combustion chamber of an engine as a corresponding member, the piston slides through the mediation of oil serving as lubricating oil. At this time, the lubricity between the piston skirt and the cylinder is important. More specifically, if the lubricity between the piston skirt and the cylinder is low when heat energy is converted into power in an internal combustion engine, it may cause a burning phenomenon and thus stop the engine. Therefore, coating of a coating (coating lay...
