Abstract
The effect of different surface treatments(pulse current anodizing, direct current anodizing and acid pickling passivating) on painting adhesion and galvanic corrosion behavior of titanium alloy Ti-6A1-4V coupled with aluminum alloy 2024 treated chromic acid anodizing was studied. Result of microstructure and tape adhesion tests shows porous film on the surface of titanium alloy treated by pulse current anodizing can effectively improve its painting adhesion . It was demonstrated by galvanic corrosion test that anodized films on titanium alloy can significantly reduce the susceptibility of galvanic corrosion between titanium alloy and aluminum alloy. Pulse current anodizing process shows better performance than direct current anodizing and acid pickling passivating in application by the results of these comparison. 关键词
