Friction Surfacing (FS) is a method to create coatings on surfaces, a commonly used approach for improving the surface properties of materials. This study investigated the deposition of an Al/SiC composite coating of AA۲۰۳۰ aluminum alloy and ۲۵۰ μm SiC particles on a plain carbon steel substrate by FS. Holes of a ۳.۵ mm diameter were made in the AA۲۰۳۰ rod and filled with SiC powder. This consumable rod was then pressed on the surface of an St۳۷ plate with an axial force of ۴۵۰ N. The rod was rotated and moved around to coat the surface of the St۳۷ substrate with a layer of Al/SiC composite. The results showed that SiC particles break down and get evenly dispersed over the surface. The deposited composite coating offered ۴۱.۶% better wear resistance and up to ۷۰% better corrosion resistance than the non-composite coating. The electrochemical impedance analysis showed two time constants in the Nyquist plots.
