Influence of Voltage on Microstructure of Micro-Arc Oxide Films on TC4 Titanium Alloy

Abstract:

The porous ceramic biologic films were prepared on the surface of Ti6Al4V (TC4) with micro-arc oxidation technology (MAO). The phase composition, microstructure and cross section morphology, surface elements composition and valence state of micro-arc oxide films were studied. Results show that with increasing of the micro-arc oxidation voltage, the better biocompatible hydroxyapatite appears on the surface of titanium alloy (TC4). The high voltage promotes the surface pore size enlarge.
