Finite Element Analysis and Experimental Investigation of Multi Layer Coating (Al2O3-TiO2 and Cr2C3) on Aluminium Piston by Plasma Spray Technique

In this study, the surface of a piston in an engine is coated with multilayer coating powder by the plasma-spray technique, and its surface behaviour is subsequently analyzed. The purpose of this study is to analyze with mechanical and thermal effects of surface coating for a piston. In this, with and without coated specimens were prepared, then the microstructure, hardness, corrosion test were carried out. From the obtained test and analyzed results, it is found that the coated specimen having improved properties may contribute towards improved diesel engine performance. The results show less deformation after getting analyzed on ANSYS on the multilayer coated piston as compared to uncoated one.
