Abstract: The study reveals surface modification of mild steel carried out using friction surfacing process. Friction surfacing is a solid state coating process which enhances the properties of the substrate. The process involves deposition of aluminium-cadmium alloy on the surface of mild steel substrate. The aluminium-cadmium alloy was used in three different proportions namely sample 1 (Al-75%,Cd-25%), sample 2 (Al-80%,Cd-20%) and sample 3 (Al-85%,Cd-15%). Lathe machine was modified to enable the process parameters of friction surfacing. Hardness test, wear test, corrosion test, flexural strength and temperature profile measurement was carried out on the surface coating. There was considerable increase in hardness as the coating showed excellent resistance to corrosion, wear and flexural strength. The temperature profile was noted for all coated samples indicating the re-crystallisation temperature.

Keywords: friction surfacing; hardness; wear; corrosion; flexural strength; temperature profile.
