Diesel engine piston ring

DY piston ring surface treatmentincludes Chromium plating, Nitriding, PCr(CrN), DTC(ta-C), PVD(CrN), DLC(ta-C). With the rapid improvement of modern engine performance, in order to meet the development needs of high combustion pressure, high output power and maintenance-free, Dongyahas successfully developed a DLC(Diamond Like Carbon) coating with low friction coefficient, high hardness, high wear resistance and significant tensile cylinder performance after years of professional research. It is currently the world's leading piston ring surface treatment technology, which is recommended that customers give priority to the choice of DLC coated ring group.
