摘要：

The phase composition and resistivity of Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe alloy after different heat treatment processes were studied. The effects of heat treatment on thickness, roughness, micromorphology and phase composition of the micro-arc oxidation coating were analyzed. The results show that since heat treatments change the phase composition of Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe alloy, the resistivity of the alloy slightly decreases after heat treatment. With the solid solution heat treatment at 850 degrees C, the thickness and roughness of the micro-arc oxidation coating are minimum, which are 48.3 and 7.45 mu m, respectively. Morphology observation reveals that the coating is compact with few cracks, after 750 and 850 degrees C solid solution heat treatment. XRD analysis indicates that the micro-arc oxidation coating is composed of anatase TiO2 and rutile TiO2.
