The current trend in I.C engine development is to construct smaller engines mutually higher specific capability outputs to approach the demands of both lower emission and customer satisfactions. In the internally combustible engine there are lot many reciprocating moving parts in which give the motion to the engine. Piston a component of engine that resist normal forces at combustion period inner portion of the engine cylinder. Many times they are build by cast iron to bears the normal forces by gases. transmit power by connect rod to crank shaft. Now a day these build by aluminum alloy to for maintaining it light weight. piston outstrip portion should be maintain load, a suggestion to overlap it by coating materials to made it such strong to resist thermal load. Piston build by of aluminum alloy overlapped by ceramic particle (Y2O3ZrO2) that bound by advanced substance (NiCrAl) is structured with device to get dimension of piston which formulate in ANSYS Work bench 15.0.7. The pressure of the 5 N/mm2 implemented on the top surface. Equal pressure get at same on both overlapped and uncoated piston and thermal observation of coated and uncoated piston carried. behavior as equal stresses, temperature change and whole deformation in pressure and convective load is to be consider with the change in coating layer of material of ceramic. Result is ceramic due to coating it can be sustain evaluate temperature load and is unresponsive towards load of structure.
