DY Piston Ring Surface Treatment


DY piston ring surface treatment includes 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, Dongya has 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.

DY Piston Ring Surface Treatments provides custom coatings and plating for piston rings and seals. Piston ring coatings and plating can extend the product life and performance of piston rings and seals and aid in relief, minimize wear, provide overall better wear and provide corrosion protection.
