The study of microstructure and wear behaviour of titanium nitride reinforced aluminium composites

Titanium Nitride (TiN) reinforced aluminium (Al) composites discover its solicitation for higher operational temperature situations. The composites were made by via powder metallurgy practice, where the reinforcement TiN is added in to Al matrix by 5, 10 and 15 percentage by weight. The drive of this paper is to study the microstructure and wear mechanism of produced composites. The SEM equipped with EDS facility has been used for the study of microstructure of composites. The wear behaviour and tribo-chemistry of the both matrix and composites has been studied as a function of sliding distance and load. The pin-on-disc has been used to analysis of the wear rate. The study reveals that the wear resistance of composites produced decreases with increase in load. However the wear resistance of Al is less than the wear resistance of composites produced. Also the wear resistance of composited increases with the increase in the addition of reinforcement.
