Preparation of a Modified Micro-arc Oxidation Coating Using Al2O3 Particles on Ti6Al4V
Author(s): Hong Li and Jin ZhangHong Li and Jin Zhang
A micro-arc oxidation coating on Ti6Al4V alloy was modified by addition of micro-Al2O3 particles to a sodium phosphate solution. The coating structure and phase were characterized by scanning electron microscopy and X-ray diffraction, and the oxidation resistance and thermal shock properties of the coating were investigated. Results showed that a coating denser than the original coating was produced. This new coating was composed of Al2TiO5 and TiO2. The oxidation resistance and thermal shock property of the coating improved with addition of Al2O3 particles to the electrolyte relative to the sample prepared without the particles in the electrolyte. Moving Al2O3 particles were adsorbed on the coating surface and penetrated through it. As a result, the phase structure and properties of the.. Read More»
