Wear is one of the most detrimental mechanisms which can affect the performance of many industrial systems. TiN coating due to its unique properties such as resistance to wear, oxidation, and heat is widely used in mechanical elements. In this research, TiN coating has been coated on steel substrate using a physical vapor deposition method. The coating’s properties have been obtained using nano-indentation test. Pin on disk wear test has been conducted while the disks are coated. The tests are conducted under three different loads and different speeds. It was shown that the samples with thicker coating show a better tribological performance. In this study, the relationship between wear and entropy has been investigated in order to predict the wear rate for different materials by predicting temperature. Also, temperature changes over time were predicted in two states of with and without coating. It was also shown that the samples with thicker coating have better wear resistance. One of the innovations of this research is the ability to establishing a correlation between the wear rate and produced temperature.
