摘要： A method for surface-treating a substrate made of a magnesium-based metal material is disclosed, which includes immersing the substrate in an electrolyte composed of an aqueous solution containing at least one component selected from the group consisting of hydroxides, carbonates and bicarbonates of alkali metals or alkali earth metals, and a film-forming stabilizer, and conducting an electrolysis to form an anodic oxide film on a surface of the substrate. Further, in accordance with the present invention, there is provided the substrate which is surface-treated by the method.

摘要： A two-step process for the coating of magnesium and its alloys is disclosed. The first step comprises immersing the magnesium workpiece in a first electrochemical solution comprising about 3 to 10 wt-% of a hydroxide and about 5 to 30 wt-% of a fluoride having a pH of at least about 12. By controlling a current density to about 10 to 200 mA/cm2, an increasing voltage differential is established between an anode comprising the pretreated article and a cathode also in contact with the electrolytic solution. Next, the article is immersed in an aqueous electrolytic solution having a pH of at least about 11 and which solution is prepared from components comprising a water soluble hydroxyde, a fluoride source and a water soluble silicate in amounts to result in an addition of about 2 to 15 g of a hydroxide per liter of solution, about 2 to 14 g of a fluoride per liter of solution and about 5 to 40 g of a silicate per liter of solution. Again, by controlling the current density to about 5 to 100 mA/cm2, an increasing voltage differential of at least about 150 volts is established between an anode comprising the pretreated article and a cathode also in contact with the electrolytic solution. This process results in a superior coating which has increased abrasion and corrosion resistance.

摘要： A process is disclosed for treating microporous coating layers deposited by anodic oxidation or plasmachemical anodic oxidation on objects made of aluminium, magnesium, titanium or their alloys. The process is useful to permanently seal the microporous coating layer and thus to protect the base material against corrosion and wear. For that purpose, silicic acid in the form of a silicic acid lyosol is deposited into the pores or capillaries of the microporous coating layer. In the silicic acid lyosol, the colloidally distributed SiO2 particles have at least one dimension smaller than the diameter of the pores or capillaries. The sol thus deposited into the pores is then coagulated or made to react with the coating layer.

摘要： There is provided a magnesium alloy member having mechanical properties and corrosion resistance and a method of manufacturing the magnesium alloy member. A magnesium alloy member has a base material made of a magnesium alloy, and an anticorrosive film formed on the base material. The base material is a rolled magnesium alloy including 5 to 11% by mass of Al. By using a base material including a large amount of Al, a magnesium alloy member having excellent mechanical properties and high corrosion resistance can be produced. In addition, by using a rolled material, the number of surface defects at the time of casting is small, and the frequency of compensation processes such as undercoating and puttying can be reduced:
