Ti surface modification for biomedical applications

Abstract

Micro Arc Oxidation (MAO) is an electrochemical approach for the surface treatment usually applied on so called valve metals such as Al, Mg and Ti. MAO is usually carried out an aqueous electrolyte, which involves a bath cooling and leads to the creation of surface contained components originated in the electrolyte. In current work, we applied a different approach of ceramic surface formation on Ti alloy used in biomedical applications. Here, MAO process conducted in molten nitrate salt at 280 deg C. The developed surface morphology, chemical and phase composition, and corrosion resistance were investigated and described in the work.
