AbstractMgO films would naturally form on a magnesium alloy matrix in the air. They are loose and porous, and the corrosion resistance of magnesium alloys is limited. Here, we demonstrate that such a loose MgO film is not merely useless in the protection of magnesium alloys, as metallic atoms could penetrate the MgO film to form intermetallic coatings on the magnesium alloy matrix. In this work, utilizing a diffusion source which contains ZnO and NH4Cl, an intermetallic layer was obtained on a magnesium alloy. The morphology and chemical composition of the intermetallic layer and the MgO film were analyzed. Results show that Mg atoms in the magnesium alloy could be utilized as a reductive agent to reduce ZnO into Zn atoms, as reduced Zn atoms are able to penetrate the loose MgO film and form a Zn-rich intermetallic layer on the magnesium alloy matrix. The concept that the MgO film could be utilized as a potential path for the surface alloying of magnesium alloys would not only deepen the understanding of the nature of the MgO film but also illuminate the surface treatment industries which usually remove the MgO film before surface modification of magnesium alloys.
