ABSTRACT:
A method for treating the surface of an aluminum-based material so as to make the surface resistant to corrosion includes the steps of contacting the surface with an aqueous cerium non-halide solution and then contacting the surface with an aqueous cerium halide solution. These steps may optionally be followed by a step of positively charging the metal surface while in contact with an aqueous molybdenum solution.
