Aluminum 7075 and its alloys are finding enormous applications in the field of automotive engineering for manufacturing of piston & its components, rivets in aircrafts construction, electrical cables, marine fittings and heavy vehicle components. During working the parts fabricated using Aluminum 7075 made contact with other surfaces usually in wear due to friction and reduction of life. To enhance the life of this parts their mechanical and wear properties must be improved it can be done by coating these surfaces or by reinforcing the metal with composites. But many times only the surface is undergoing wear and only the surface properties need to be enhanced. In such case reinforcing by composites become costly, coating the surface with a metal or its oxide is another popular way of improving the material properties. In this paper titanium dioxide is coated on Aluminum7075 with 110µm thickness is tested in Pin on disc machine for testing in dry condition and different test parametersare studied based on the experimental results conclusions are arrived.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
