NOVELTY - Production of graphene protective film-containing magnesium alloy comprises cleaning magnesium alloy surface, removing stains and passivation film, soaking in protective agent, forming protective film, chemical vapor depositing, heat treating, removing protective film, depositing graphene, plasma enhanced chemical vapor depositing, and forming graphene protective film. Protective agent is polymethyl methacrylate, polydimethylsiloxane or polycarbonate. USE - Method for preparing graphene protective film-containing magnesium alloy. ADVANTAGE - The alloy is stable, dense, corrosion-resistant, and has high surface conductivity. The method is simple and easy.
