Title: Piston ring
Inventor: KAWANAMI SHIZUO
IPC: F02F5/00
Filed: 1990-03-20
Abstract: PURPOSE:To enable stable increase of thickness by forming a groove in the outer peripheral slide surface of a piston ring, arranging a plurality of electrodes matching the shape of the groove during application of chrome plating, rotating a piston ring, and applying blasting on the surface of each layer. CONSTITUTION:A ring body 1 is formed of a cast iron material and a part 2 where rigid chrome plating is laminated is formed in a groove part formed in the outside (slide surface) of the ring body. This shape prevents the occurrence of a defect to the corner parts of the two ends by which inhibition of the increase of the thickness of chrome plating is caused. In this plating method, masking 3 is applied on a part where no plating is applied, a plurality of electrodes 4 are located at intervals of a given distance in a groove 1a, and the ring body 1 is rotated by means of a rotation jig 5. This constitution uniformizes the thickness of plating and facilitates plating of each layer. Numeral 6 is plating liquid. When multilayer plating is effected, blasting is applied on a surface to form a finely uneven surface, and peeling between layers is prevented from occurring.
