In automotive failures has become a major concern. Piston is one of the main parts of the engine. In this report a study is conducted on the piston failure by using different methods. The major causes are increase in temperature, improper carburization techniques, improper coating, improper combustion, the improper combustion causes carbon deposits etc. There are different types of methods are used to analyze the piston failures they are wear bench test, hardness test Vickers meter to know the depth of carburized layer etc. Visual examination is conducted by the SEM (Scanning Electron Microscopy), EDS (Energy dispersive spectrometry), EDX (Energy Dispersive X-ray spectroscopy). Spectroscopy Chemical analysis is used to know the chemical composition in the piston. The failure of the piston was studied using finite element software such as ABACUS and ANSYS.
