Effect of SiC Coating on Fuel Consumption and Emission Control in IC Engines

Thermal spray coatings are depositions of materials which has been melted or plasticized immediately prior to projection onto the substrate. The metal and the application system used vary but most applications result in thin coating applied to surface requiring improvement to their corrosion or abrasion resistance properties. In this paper the usage of thermal spray coating on the piston of I.C engine for reducing the emission and thereby improving the efficiency are explained. The silicon carbide particles were coated on the piston and the mileage and emission tests have been carried out after installing the coated piston.
