Study on Preparation of Micro-Arc Oxidation Film on TC4 Alloy with Titanium Dioxide Colloid in Electrolyte
Source abstract
Abstract
The micro-arc oxidation film on TC4 alloy was prepared using a multifunctional micro-arc oxidation (MAO) power source. The effect of nano-titania colloid addition on the growth process, microstructure, and comprehensive mechanical properties of titanium alloy micro-arc oxidation films was studied by gradient concentration. The results show that, with the increase in titanium dioxide colloid content, the intensity of the discharge phenomenon during the MAO process increases, and the average current density gradually increases. The film thickness is gradually increased from 111.06 μm to 159.8 μm, and the roughness first decreases and then increases. The XRD results show that the rutile content in the film layer is increased with titanium dioxide colloid in the electrolyte. This resulted in an increase in the density of the film, and lead to the corrosion resistance of film improved. When the concentration of titanium dioxide colloid is 1.5 g/L, the comprehensive performance of the film is the best.
