A piston is one of the most important parts of an internal combustion engine. This part supports the combustion pressure of the gas in the cylinder. They are generally made of cast iron, which can withstand pressure. Recently, aluminum alloy is used for weight reduction. Since the top surface of the piston needs to support the load, it is recommended to cover it with a coating material. Ceramic coatings are increasingly used for protection between various engine parts to increase wear resistance, reduce friction and improve heat shielding. In this work, the pistons were designed with the software CATIA. The complete design was imported into ANSYS software and analyzed. Thermal analysis of the piston was performed by choosing an aluminum alloy as the piston material and coating it with different coating materials such as silicon carbide, titanium carbide and magnesium zirconium to a thickness of 1 mm. It was observed that the temperature of the coated piston crown was higher than that of the uncoated piston, and that the temperature also increased with increasing coating thickness. Results were presented in tabular form and compared to find the most suitable design.
