The surface microstructure of a metallic material influences the properties such as surface hardness, wear resistance, corrosion resistance, and other organic matter activities. Friction stir processing (FSP) is used in the surface modification owing to its advantages, such as low thermal effects and negligible interfacial reaction, over the liquid state processing routes. Aluminium matrix surface composites fabricated using FSP with different reinforcement species can be useful in improving the corrosion behavior of the material. The surface modification can also be a beneficial step to improve the anti-bacterial nature of the additively manufactured parts. FSP can also be used to produce internal channels for efficient sinks.
