Beschreibung
Zusammenfassung:	This invention relates to magnesium alloy surface processing method, the procedures are that a. it is processed by the mixed solution of hydrofluoric acid and sulfuric acid. b. then it is cleaned by pure water to wash surface residual agent. c. it is processed by hydrofluoric acid. d. then it is washed by pure water to wash surface residual agent. e. it is processed by calcium carbonate water solution, so the magnesium alloy surface processing is finished. In this invention, simple etching solution is used to etch the alloy surface at room temperature to make material surface single face, and put an end of corrosion.
