Dry Sliding Wear Behaviour of Al 7075 T6 Coated by Plasma Spray Process

Abstract:

-Al7075 T6 alloys are widely used in the aircraft, automotive and die and mold making industry, yet at any time aluminium components should be designed with a third body or in an harsh environment they must be protected with an overlying coating inorder to increase their useful lifespan and improve their surface performance especially in wear and corrosion. The most wide spread technique used to modify the surface properties of Al7075 T6 among them one of the most promosing technology is plasma spraying. It is widely used to manufacture anti-wear and anti-corrosion coatings on to a large class of bulk materials. Extreme performance and high flexibility are the Main characteristic of the coatings achievable by Plasma Spray process. In this work Nickel Carbide + Chromium Composite coating was successfully prepared and deposied with various thicknesses on the Aluminium alloy surface. Nickel Carbide + Chromium composite coating exhibits a significantly increased wear resistance property in the material. The result obtained in this work indicated that the plasma spraying method will be the promising process to coat the composite coating on aluminium based alloy.Keywords: Al 7075 T6, Plasma Spray Process, Nickel Carbide + Chromium
