摘要： PROBLEM TO BE SOLVED: To provide an anticorrosive coating structure for a magnesium metal showing an excellent durability by sufficiently bonding an anodic oxide film and a substrate, i.e. the magnesium metal at their interface.
SOLUTION: The anticorrosive coating structure, wherein a silane-modified resin layer is attached on the surface of the magnesium metal, is obtained by coating the surface of the magnesium metal with an oxide layer formed through anodic oxidation, applying the silane-modified resin layer containing 0.1-2 pts.wt. alkoxysilane against 1 pts.wt. resin comprising an acrylic resin or an epoxy resin over this oxide layer and infiltrating the silane-modified resin through pores penetrating the oxide layer to the surface of the magnesium metal. Once reaching the surface of the magnesium metal, the silane-modified resin directly adheres and binds to the magnesium metal and bonds the oxide layer to the magnesium metal. Therefore, multiple anticorrosive coating layers become united and tightly fixed onto the surface of the magnesium metal.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a magnesium alloy having stable fine crystal grain structure and excellent formability by solving such problem as coarsening of crystal grains, obstruction to formability and increase of energy consumption and to provide a magnesium alloy member.
SOLUTION: After applying a solution-treatment to the magnesium alloy, in a first forging process, a pre-strain of not less than at least 0.4 is given in a temperature range of 250-400°C and thereafter, an ageing treatment is applied and successively, a secondary forging is performed at a necessary temperature of not higher than the forging temperature. In this way, the fine grains of magnesium compound after ageing-treatment are precipitated and the coarsening of the crystal grains is prevented during the heating process in the secondary forging process. Further, the formed product having about ≤10 μm average crystal grain diameter and the stable fine crystal grain structure of ≤5 μm average crystal grain diameter under a suitable condition with a fining action by forging, and the material excellent in formability for the following working process, can be obtained.
