Title: Piston ring
Inventor: SHINADA MANABU
IPC: F02F5/00
Filed: 1988-09-27
Abstract: PURPOSE:To obtain a piston ring of a good initial running-in property and an excellent abrasionproof property by forming a composite dispersion plating layer of an adequate hardness on a titanium nitride membrane layer of an excellent abrasionproof property. CONSTITUTION:This piston ring 1 for internal combustion engine has a dual structure made by forming a titanium nitride layer 2 made in a reactive ion plating as the first layer and a silicon nitride particle dispersion nickel-cobalt- phosphorous alloy complex plating layer as the second layer in this order at least on the outer peripheral sliding surface. Since the material of the silicon nitride particle dispersion complex plating membrane 3 of the upper layer (the second layer) is somewhat softer than that of the lower (the first) layer of the titanium nitride layer 2, it presents a good adaptability to the cylinder at the initial starting period of the engine, and at the same time, it is not worn away rapidly. And since the titanium nitride membrane 2 has a high hardness, it maintains a good abrasionproof property for a long period (even after the upper layer is worn away).
