MAGNESIUM ALLOY ANODIZING SOLUTION AND PREPARATION METHOD THEREFOR, AND METHOD FOR ANODIZING MAGNESIUM ALLOY

摘要

Disclosed is a magnesium alloy anodizing solution, wherein same is an aqueous solution containing hydroxides, silicates, meta-aluminates, phosphates, ethylene glycol and glyoxylic acids. Further provided are a method for preparing the magnesium alloy anodizing solution and a method for anodizing a magnesium alloy by using the magnesium alloy anodizing solution. The magnesium alloy anodizing solution can effectively reduce the pore size on the oxide film and improve the pore uniformity so as to improve the subsequent dyeing effect.
