In order to improve corrosion resistance on magnesium alloys, coating the surfaces of magnesium alloys with high purity magnesium by applying a vapor deposition technique has been proposed by the authors. For practical application of this technique to engineering products, a new apparatus has been developed, which enables one to carry out the coating on a relatively large substrate with 250×250 mm in size. The apparatus has two vacuum chambers for evaporation and deposition, which are separated by a gate valve. For an evaporation source and a substrate, 3N–Mg and AZ31B magnesium alloy were used, respectively, which were put into the evaporation chamber and the deposition chamber, respectively. The evaporation source was heated at 823∼973 K, while the substrate was held at 323∼523 K, deposition time was 1.8 ks. The resulting substrate was coated with high purity magnesium with about 20 to 25 μm in thickness. In this study, the fundamental conditions of coating for the apparatus, microstructures of the coated layer, corrosion resistance, and adhesion between the coated layer and the matrix are described.
