A kind of environmental titanium alloy anode oxidation process was introduced in this paper.Different from traditional process

there were not toxic substances such as hydrofluoric acid and chromic acid in this process

which would reduce the effect on environment.And more

the process was simple

the raw material was cheap and easy to get

and the production cost was low.The oxide film from anode oxidation process had good capability of wear resistance and corrosion resistance.The surface roughness of the oxide film was reduced greatly after treated by seal and could resist salt mist corrosion for over 1 500 h.The preponderances of titanium alloy anode oxidation process were elaborated based on some shortcomings and difficulties of traditional anode oxidation process.The application present situation of titanium alloy anodic oxidation process was analyzed

and its application tendency was prospected.
