Abstract

This study is about electrolytically polishing of 316L stainless steel boride surface, which is used in the field of implantology as biomaterials. The objective of this electrolytic polishing treatment is to improve the biocompatibility of this material, in particular its surface state. Tests have shown that electrolytically polished 316L has improved corrosion resistance over 316L boride. The formation of the Fe2B boride layer does not allow us to use the same polishing technique as that used for the 316L substrate. The main objective is to develop the proper electrolytic polishing technique applied to the boride layer in order to compare electrolytically 316L and electrolytically polished 316L boride.

Keywords: Stainless steel; boriding; biomaterial implant; electro-polishing
