Wire arc additive manufacturing utilising tungsten inert gas (WAAM-TIG), along with a twin wire feed mechanism, has been utilised to fabricate advanced SS316L-IN625 alloys. Different compositions of SS316L and IN625, varying from 25% to 75%, were used to analyse the influence of Fe, Ni, and Cr content on the tribo-mechanical and corrosion characteristics of the developed alloys. The microstructural and EDS analysis reported a homogeneous blending throughout the deposition. It was found that the Ni content drives properties, such as an increase in micro-indentation and scratch hardness, and fracture toughness of ~18%, ~22%, and ~10%, respectively. Similarly, an increase in Cr content showed a significant improvement in corrosion resistance as found in the electrochemical corrosion test. These results show that by selective control of these two materials, the resultant characteristics could be altered to fulfill the demands in structural and corrosive environments as per the required applications. |
