Protective coating is identified as a fundamental key to provide strong mechanical resistance, high hardness and high wear resistance for coated components. Aim of this project is to predict the micro hardness of thin Titanium Aluminium Nitride (TiAlN) coated stainless steel substrate (SS410) using Vickers hardness tester. In this regard, to predict optimum temperature and thermal stress developed in thin Titanium Aluminium Nitride (TiAlN) coating on stainless steel substrate (SS410) using Finite Element Analysis (FEA). Most of the researchers have analyzed coating stress in 2D static analysis, with this background a Finite Element Model for Physical Vapour Deposition (PVD) coating substrate system has been investigated. The stress developed in the coating structure to be analyzed using FEA and coating deposition temperature to be optimized with respect to the minimum stress. Also, conduct the hardness test and predict the optimum temperature at which the micro hardness of substrate is maximum.
