SLIDING MEMBER FOR AUTOMOBILE ENGINE

Japanese Patent JP2006144100

A

To provide a sliding member for automobile engines in which a low coefficient of friction is realized and the crack, exfoliation, etc., probably arising when a hard carbon thin film is applied to the sliding member are suppressed.

The sliding member for automobile engines slides in the presence of a lubricant, and is formed by coating a base material surface with the hard carbon thin film, in which Ra of the base material prior to the coating is ≤0.02 μm, and the film thickness of the hard carbon thin film deposited by an arc type ion plating method is 0.5 to 2.0 μm. The surface hardness of the hard carbon thin film is 1,500 kg/mm2 in Knoop hardness and the film thickness is 0.5 to 2.0 μm. The hydrogen atom concentration of the hard carbon thin film is ≤1atom.%. The lubricating oil containing fatty acid ester-based ash-free friction regulating agent, an aliphatic amine-based ash-free friction regulating agent, a polybutenyl succinicimide and a zinc dithiophosphate is used.
