Abstract

This invention uses a simple etching solution to etch the surface of magnesium alloy in a short time at room temperature to remove Mg17Al12 and Al-rich-α phase to form a single phase on the surface of the sample and preclude the erosion by Galvanic effect among α-phase, Mg17Al12 phase and Al-rich-α phase. This invention can effectively increase the erosive resistance and acquire a more uniform surface roughness and will benefit the adhesion of follow-up painting. Because the result of this invention is to remove the other phases from the surface of magnesium alloy and not to form a thin film, consequently, no special procedures are needed in the recycling process. The profits of this invention are that there will be no heavy metal pollution, fluorine, etc. Fluorine will destroy the ozonosphere and lead to the greenhouse effect.
