The piston is considered to be one of the important parts of the internal combustion engine. It is a part which bears the pressure of the combustion of the gas inside the cylinder. Normally they are made up of cast iron which bears the gas weight. It is used to deliver the power via linking rod to the main shaft of the engine. Nowadays they are made of aluminum alloy to keep it lightweight. As the top surface of the piston has to bear the load, it is prudent to cover it with some coating material so that it could bear the thermal load. Piston made up of gray cast iron coated with ceramic material (MgZrO3) which is bonded by special material (NiCrAl) is intended for M550d x Drive sedan by machine design approach to resolve the dimensions of the piston and then it is modeled in ANSYS Workbench 17.1. The pressure of the 5 N/mm2 is applied on the piston. The equivalent stresses are found to be same for both coated and non-coated piston. Thermal analysis of both coated and the non-coated piston is done. The properties like equivalent stresses, temperature variation and total twist under pressure and thermal load are resolute with the change in the thickness of ceramic coating material. It is completed that ceramic coated piston is able to handle thermal load and is indifferent towards structural load.
