dc.description.abstractPistons on internal combustion engines that are constantly subjected to high pressure and temperature should be light, resistant to heat, resistant to corrosion and have adequate hardness to work more efficiently and to have longer lifecycles. For this purpose, piston surfaces are coated with thermal barrier that increases resistance against heat and corrosion. In this study, temperature distribution on piston surfaces were numerically analysed for ceramic coating on a piston. For this purpose, it is assumed that 100 mu m NiCrAl coating is applied as bond coat on piston upper surface. This coating was coated with MgZrO3+NiCrAl alloy with different alloy ratios for different coating thicknesses. MgZrO3+NiCrAl alloy thickness was changed between 200 mu m and 600 mu m. For all analysed coating thicknesses, MgZrO3 ratio in the alloy was changed between 100 to 10% and simulations were repeated for different alloy rates. As a result of these analysis, it was determined that as MgZrO3 ratio in the alloy decreased, piston upper surface temperature decreased as well. For all alloy ratios, maximum temperature was observed on piston upper surface. Additionally, it was determined that as piston upper surface coating thickness increased, piston upper surface temperature increased as well.en_US
