Thermal Analysis of a Piston Coated with SiC and MgOZrO2 Thermal Barrier Materials

Abstract

In this study, motor piston was designed by using solid-works which is a computer aided modeling program and its thermal analyses were performed. In the study performed for this purpose, the motor piston (AlSi) was coated with MgOZrO₂ and SiC ceramic material, and its thermal analyses were performed. 3-D modeling and analyses of the piston were performed via the program. Thermal analyses of motor piston, standard piston material and coated materials were performed, and they were examined comparatively. In the thermal analyses of ceramic coated pistons compared to standard pistons, an increase of 21-26% was determined in the combustion chamber temperature of the piston, a decrease of 19-24% was determined in the pin housing of piston and a decrease of 14-17% was determined in the piston skirts.
