クロムめっきのみでは対処しきれなくなりつつある。Piston rings coated with hard chrome plating have long been the mainstream surface treatment for piston rings because they have excellent wear resistance and cause less wear on the mating cylinder. However, in recent years, with the increase in engine output and performance, the conditions to which piston rings are exposed have become increasingly severe.
Piston rings are now required to have excellent wear resistance and seizure resistance. These demands cannot be met by conventional hard chrome plating alone.

分ではなかった。In order to deal with this difficult situation, a technique has been disclosed in which the roughness of the circumferential surface of the piston ring is reduced to a predetermined value or less. According to this technique, the wear resistance and seizure resistance were much improved compared to conventional hard chromium plating, but the seizure resistance was still insufficient.
