Over the years, widespread diffusion of additive manufacturing, especially to produce metal objects, and awareness their poor surface quality due presence a significant roughness, have highlighted need develop suitable post-processing treatments. In this regard, electropolishing techniques are ideal high versatility, even on geometrically complex or small-sized which difficult treat with that r...

Abstract The traditional of mixed electrolyte H 2 SO 4 and 3 PO widely used in electropolishing 304 stainless steel. Due to environmental protection safety issues, there is an urgent need develop more environmentally friendly electrolytes. In this study, steel was electropolished by plasma using a oxalic acid citric acid, which are concentration were 0.01 M, 0.05M, 0.1M, 0.3M 0.5 respectively. ...
