摘      要：Two two-step techniques, called TS2/TS7 and TS3/TS7, respectively,have been developed to form cerium conversion films on the surface ofindustrial pure aluminum. The tested material was cathodicallyelectrolyzed in the al- kaline solution containing cerium salt, anduniform films containing cerium were obtained after the two-steptreatment. It is found that the films obtained by TS2/TS7 and TS3/TS7techniques are about 4.0 and 3.0 um in thickness, respectiv- Ely. Thematerial has better corrosion resistance in the chloride solutionafter the two-step electrolysis treatent compar- Ed with the one-steptreated and naked specimens.
