The evolution, development, application and future of a new surface treatment for piston rings and cylinder liners. The treatment has evolved over the last 20 years. It consists of the impregnation of the wearing surfaces with pure silicon carbide. The research background demonstrates that the material is bonded intimately. The process can be applied to liners and rings in a variety of basic materials. The application is to any mechanism where the physics of rubbing surfaces cause wear problems. The process is protected by patents in the main automobile producing countries in the world.
