Tribological Behaviuor On Aluminium –Nano Metal Matrix Compositre with Addition of Titanium Di Oxide and Solid Lubricant (Powder Metalurgy Process)
Keywords:
Aluminium nano MMC, solid lubricant, tribology, powder metallurgyAbstract
Aluminium metal matrix composite with improved mechanical and physical properties are emerging as an essential part of the aerospace and automobile applications. The aluminium metal matrix composite reinforced with nano titanium di oxide with added graphite as solid lubricant has better tribological properties. This study is made with an attempt to trace the preparation and wear properties of the composite. Here the aluminium matrix with 7% titanium dioxide and graphite with equal percentage in nano size. The wear test conducted in pin on disc apparatus with loads 5N, 7N, 10N, at the velocities of 1.5m/s, 2m/s, 2.5m/s. The optimal condition attaining the minimum specific wear rate is at the sliding velocity of 1.5 m/s and load of 5 N with the 5 gram sample.
