Abstract

PURPOSE:To obtain a wear-resisting property and a scuff-resisting property and raise the productivity of a piston ring, by quenching a part of the sliding side of the piston ring to produce a self-quenched layer consisting of a hard and a soft regular parts. CONSTITUTION:If the piston ring is a compression ring made of steel, two self- quenched layers 2 are produced on the sliding side of the ring 1 by a CO2 laser oscillator. The quenched layers can be made by projection of laser rays without causing the deformation of the ring, the reduction in its tension, etc. Therefore, a hard and a soft metal structures 2 are provided on the sliding surface of the ring 1. The hard structure has the wear-resisting property. The soft structure is abraded and recessed in the initial stage of service. As a result, an oil reservoir is provided on the sliding surface of the ring. This leads to the prevention of initial scuffing and the improvement on the wear-resisting property and heat-reducing property.
