Filed: 1984-02-16
Abstract: PURPOSE:To aim at enhancing the wear-resistance of a piston ring, by forming a nitride layer on the entire surface of the highly durable piston ring, and as well, by forming a hard chromium plating layer on the nitride layer from which a chemical compound having a high N concentration is removed, thereby a slide surface is formed. CONSTITUTION:A nitride layer is formed on the entire surface of a piston ring 1 made of martensite group steels, and a chemical compound having a higher N concentration on the outermost surface of a piston ring mother material is removed, excepting the nitride layer on the inner peripheral surface of the piston ring 1. That is, a piston ring mother material 2 is formed on the outer peripheral surface thereof with the nitride layer 3 having more than 700Hv and a hard chromium plating layer 4 having more than 850Hv formed on the slide surface of the nitride layer 3. Accordingly, the piston ring is excellent in fatiguerestant strength and as well as has a high durability. Further, the close affinity of the hard chromium plating, and as well abration is small in the associated cylinder.
