Abstract

The in-situ ceramics coating were fabricated by the micro-arc oxidation technology in order to improve the corrosion resistance of Ti6Al4V alloy. The silicate electrolyte system was introduced to reduce the applied voltage of the MAO coating. The influence of applied voltage on phase composition, surface morphology and dynamic polarization behavior was investigated. The addition of applied voltage make the MAO pore bigger and quantity of MAO pore reduced. The introduce of MAO coating on the surface of Ti6Al4V alloy improved corrosion resistant performance.
