  • Publication number: 20030176252
    Abstract: A silent chain having improved wear resistance comprising link plates that have a pair of pin holes that are finished using a punch with a round edge portion, and connecting pins with a carbide layer formed on a the base material of the pin. The carbide layer includes vanadium carbide as the principal component and chromium carbide as the secondary component. The carbide layer is formed on the outermost surface of the base material. A boundary layer is formed in the boundary region between the carbide layer and the base material. The boundary layer includes vanadium carbide whose percentage content decreases sharply and chromium carbide whose percentage content increases sharply. Since the carbide layer formed on top of the base metal consists principally of vanadium carbide it is possible to prevent peeling from the surface of the carbide layer.
