Abstract

Abstract: This research work aimed to investigate mechanical and surface properties of post-processed stainless steel 316L (SS316L) fabricated through additive manufacturing (AM) process. The AM printed samples were post-processed by nitriding and shot peening process and used for different surface characterizations such as surface roughness, hardness and microstructure. The results showed improved surface roughness of shot peening part and increase in hardness after post-processing. The improvement in the surface roughness has been significant of around 43 % to 62 % at different energy density. The improvement in hardness is more for nitrided parts as compared to the shot peening.
