Abstract

The application of dry process technology to piston rings is introduced. The transition of surface treatment technology from the hard chromium plating to DLC coating is explained with the background about improving the performance of piston ring to respond the social requirement such as the improving fuel economy. Finally, the possibility of the applied technology to the future engine components by using the super-lubrication phenomenon by ta-C coating under the environmentally friendly lubricant is discussed.
