Abstract
Recent trends shows powder metallurgy composites are most familiar due to its wide applications in the areas like defense, aircraft, automobile, sports etc. Powder metal mixtures are prepared for surface coating in the areas where high corrosive and heat resistance are required. Carbon Nanotubes are widely used in the field of engineering with its remarkable mechanical, electrical properties and very good reinforcement in composite preparation. In this research, multi wall Carbon Nanotube along with Aluminum and Silicon powder were mixed thoroughly by ball milling process. The powder mixture (AlSiCNT) reveals that Carbon Nanotube are well dispersed uniformly with Aluminum and Silicon which promotes toughening mechanism with good reinforcement. The AlSiCNT mixture is then coated over the surface of Aluminum alloy 6061 and Stainless steel 304 L by plasma spraying technique. Tensile test, micro hardness tests with micro structural study were carried out over the composite. Coated composite reveal better mechanical properties than the base metals.
