Method for manufacturing piston ring, involves cutting laminated composite material to produce inner peripheral surface, outer peripheral surface, upper flank surface and lower flank surface

摘要

The method involves cutting a laminated composite material (1) to produce an inner peripheral surface, an outer peripheral surface, an upper flank surface and a lower flank surface. The laminated composite material is developed in a moderate condition, such that one of the flanks of a piston ring base body (5) is made of a wear-resistant material.
