PISTON RING

摘要

The present invention relates to a piston ring, particularly designed for use in the groove of a piston of an internal combustion engine and/or a compressor, provided with a metallic base (10) having chamfers (15) in its final dimension and to which one applies nitriding consisting exclusively of a nitrided diffusion layer (5), without the need for subsequent machining and guaranteeing a considerable improvement in the mechanical properties of the component, more concretely with regard to residual compressive tensions and fatigue resistance.
