Abstract

PURPOSE:To enhance surface hardness and abrasion resistance of a piston ring and contrive to save a step of repolishing the surface of the piston ring, by coating the surface of the piston ring with titanium nitride by ion plating. CONSTITUTION:The piston ring 2 on which a high negative voltage is impressed is placed in a vacuum treating tank 1 provided with a vacuum atmosphere containing an inert gas, and a glow discharge is developed between the piston ring 2 and a titanium vapor source 3 placed oppositely to the ring 2. Titanium atoms evaporated from the vapor source 3 are ionized when passing through the glow discharge region, and the resultant nitride collides against the surface of the piston ring 2 to form a nitride ion layer, or the titanium atoms are accumulated on the surface of the piston ring 2 as they are, and are then converted into the titanium nitride layer by being bombarded with nitride ions.

A glow discharge is generated at the s-ray 11 (3) and the 0-section, and the titanium atomic beam glow discharge region f evaporated from the evaporation m (3) is generated.
: Passing liK is ionized and becomes nitride, which enters the piston ring (2) and is deposited on the piston ring surface in the form of titanium atoms. Form a surface titanium nitride layer.

要がなく処理工程を簡略化出来る勢の効果がある。In this way, the piston ring of the present invention is coated with titanium nitride using an ion plate. According to this method, the ima degree is increased and wear resistance is improved, and the relatively thin titanium nitride is coated with titanium nitride. Since a layer is formed, there is no need to re-polish the surface of the piston ring as in the conventional method, which has the effect of simplifying the processing process.
