<br/><br/> The composition and surface microstructure of a component play a decisive role in determining the surface dependent engineering properties (hardness, wear, fatigue, corrosion and oxidation resistance). Surface engineering process aims to control heating and cooling of metallic materials to alter their physical and mechanical properties without affecting the bulk material. Conventionally, surface treatment processes like flame hardening, induction hardening, carburizing, nitriding, carbonitriding and different hardfacing techniques are usually employed in enhancing the wear resistance property of Fe-based alloys. These processes suffer from various restrictions, i.e., time and energy consumption, complex heat treatment schedule, non-controllable heat affected zone, lack of solid solubility limit, quenching required and slower kinetics. Furthermore, few of these conventional techniques are not environment friendly
