Experimental Investigation of Mechanical and Tribological Behavior of Al 6061- Tio2 Processed By Powder Metallurgy Technique

Metal matrix composites have created distinct interest as of late adding to the strength to weight proportion, stiffness, good ductility, excellent corrosion resistance, availability and low cost good creep resistance & fatigue properties over that of conventional engineering materials. This is the reason past the extended requirement for advancement of composites with unique properties. Powder metallurgy is an ideal method for production of MMCs because of the capability of process to produce near net shapes with minimal material waste associated with production. Tribological and mechanical properties have a noteworthy part in production of MMC's utilized extensively in automotive and aviation industries. The present investigation is an attempt made to disperse nano sized silicon carbide particles in Al 6061 base alloy by powder metallurgy technique and study its effect on wear properties of Al 6061 alloy. Addition of Titanium Dioxide particulate reinforcement has been varied from 5% 10% & 15% by weight of base alloy. Powder metallurgy composite specimens fabricated were machined according to test standards the tribological and mechanical properties has been examined and compared with that of base material Al6061 alloy significant improvement in wear properties, hardness is noticeable with increased volume wt% of TiO2.
