Occasional abnormal wear elongation, which occurs in a silent chain when exposed to lubricating oil in a deteriorated condition due to oxidation, is avoided by polishing the inner link plates of the chain to a surface roughness of 0.5 mum Rz or less, chromizing the inner link plates, forming a vanadium carbide layer on the connecting pins of the chain, and then polishing the connecting pins to a surface roughness of 0.5 mum Rz. |
