摘要：
The present invention refers to a piston ring for internal combustion engine, having an outer surface of a coating of Chromium Nitride (CrN and Cr2N) and Niobium Nitride (NbN and Nb4N3), capable of offering greater resistance to peeling of the coating, also maintaining an excellent level of resistance to wear and tear and scratches to the layer of Chromium Nitride deposited.
