To improve the corrosion resistance of an electrogalvanized steel sheet, we deposited magnesium film on it using a vacuum evaporation method and annealed the films at 250-330℃. The zinc-magnesium alloy is consequently formed by diffusion of magnesium into the zinc coating. From the anodic polarization test in 3% NaCl solution, the films annealed at 270-310℃ showed better corrosion resistance than others. In Xray diffraction analysis, ZnMg₂ was detected through out the temperature range, whereas Mg₂Zn<SUB>11</SUB> and FeZn<SUB>13</SUB> were detected only in the film annealed at 310℃. The depth composition profile showed that the compositions of Mg at 270-290℃ are evenly and deeply distributed in the film surface layer. These results demonstrate that 270-290℃ is a proper temperature range to produce a layer of MgZn₂ intermetallic compound to act as a homogeneous passive layer.
