Embodiment Construction

[0021] figure 1 The wear-resistant coating 10 of the present invention is formed on a parent body 11, such as a connecting pin of a silent chain, which is opposed and in sliding contact with a material 12, which may be a chain plate of the chain. The base coat 10a is composed of a hard inorganic material such as vanadium carbide. Particles 10b, such as alumina particles, are dispersed in the base coat. figure 1 Arrows seen at the upper and lower parts of , indicate the sliding direction of the matrix 11 relative to the opposing material 12 .

[0022] Such as figure 1 As clearly shown, since the wear resistant coating 10 has dispersed alumina particles 10b in the vanadium carbide base coating 10a, a portion of the dispersed particles 10b is exposed on the coating surface.

[0023] Coating 10 may be formed by adding alumina particles to the powder in a diffusion coating process by a powder loading method. However, the method of forming the wear-resistant coating 10 on the su...

Abstract

A wear-resistant coating, capable of imparting excellent wear resistance to a silent chain, comprises a base coating consisting of a hard inorganic material having interspersed particles of a hard inorganic material different from the inorganic material of the base coating. A part of the interspersed particles is exposed on the surface of the coating. The coating has superior oil-retaining properties as a result of gaps formed at the interface between the particles and the base coating, and the superior oil-retaining properties contribute to the wear-resistance of the coating.

Description

technical field [0001] The present invention relates to a wear-resistant coating suitable for use as a surface coating for a silent chain used as a drive chain in automobiles, motorcycles or the like. Background technique [0002] In recent years, silent chains have been used to transmit power under high speed and high load conditions. In a typical silent chain, a plurality of chain plates P are arranged in alternating layers interconnected by connecting pins Q, each chain plate being bifurcated so as to provide a pair of teeth on one side, as shown in FIG. 3 . On the bifurcated part of each chain plate P, the two outer tooth side surfaces R1 are used as the meshing surfaces in the outer tooth side meshing silent chain, or the two tooth side surfaces R2 are used as the meshing surfaces in the inner tooth side meshing silent chain . In either case, the engagement surface engages the sprocket and transfers power from the chain to the sprocket or from the sprocket to the chai...
