Abstract

New modern technology of surface treatment of stainless steel was shown. Deep eutectic solvent Reline was proposed as a highly efficient electrolyte for electropolishing of AISI 304. Anodic treatment of AISI 304 steel samples in Reline leads to an improvement in appearance and surface properties. Electropolished samples are characterized by low roughness, shiny surface, less wettability and as a consequence of higher resistance to corrosion.
