Abstract— The desire to reach higher efficiencies, lower specific fuel consumption and reduced emissions in modern engines has become the primary focus of engine researches and manufacturers over the past three decades. Ceramic coating is a solution to such problems as they provide good thermal barrier properties for designers. In the design of adiabatic engines, reducing incylinder heat rejection requires very special thermal barrier coatings on the engine combustion chamber. Partial Thermal barrier coating (TBC) on the top surface of the piston is considered as a solution for reduction of unburned Hydrocarbon (HC) emission produced by incomplete combustion with respect to crevice volume when engines start. The TBC on the top piston surface decreases the thermal conductivity and increases the unburned charge oxidation, so that the metallic substrates will be exposed to lower peak temperature thereby reducing the thermal stress in engine components. Also thermal barrier coatings on other elements of combustion chamber of internal combustion engine offer advantages including fuel efficiency, multifuel capacity and high power density. Therefore, thermal barrier coating (TBC) technology is successfully applied to the internal combustion engines, in particular to the combustion chamber [1].
