Surface treatment method for aluminum alloy and surface treatment method for magnesium alloy |
摘要 |
The present invention provides a surface treatment method for an aluminum alloy and a surface treatment method for a magnesium alloy, which enable providing the surface of an aluminum alloy containing magnesium or the surface of a magnesium alloy with sufficient corrosion resistance to corrosive gases, while preventing the surface from scattering magnesium therefrom even when used in a vacuum at a temperature of not less than 300° C. In this method, a carbon fluoride compound is applied over the surface of the aluminum alloy containing magnesium or the surface of the magnesium alloy, followed by heating in an oxygen atmosphere, thereby forming a fluoride passivation film. |
