    摘要: Provided is a method of producing an aluminum structure using a porous resin molded body having a three-dimensional network structure, with which it is possible to form an aluminum structure having a low oxide content in the surface of aluminum (i.e., having an oxide film with a small thickness), and in particular, it is possible to obtain an aluminum porous body that has a large area. The method includes a step of preparing an aluminum-coated resin molded body in which an aluminum layer is formed, directly or with another layer therebetween, on a surface of a resin molded body composed of urethane, and a step of decomposing the resin molded body by bringing the aluminum-coated resin molded body into contact with concentrated nitric acid with a concentration of 62% or more.

    摘要: An element recovery method and an element recovery apparatus are provided by which an element containing a high-purity rare earth element can be recovered at low cost. The element recovery method includes the steps of: preparing molten salt containing a rare earth element; and controlling electric potentials in a pair of electrode members at prescribed values while keeping the pair of electrode members in contact with the molten salt, thereby depositing the rare earth element existing in the molten salt on one of the pair of electrode members. In this way, as compared with the conventional wet separation method, an element such as a rare earth element that is to be recovered can be directly recovered from the molten salt in which the element is dissolved, so that the steps of the recovery method can be simplified and reduced in cost.

    摘要: A magnesium alloy structural member having excellent corrosion resistance is provided. The magnesium alloy structural member includes a magnesium alloy substrate that contains more than 7.5% by mass of Al and an anticorrosive layer formed on a surface of the substrate by chemical conversion treatment. The substrate contains a precipitate, typically, particles dispersed therein. The particles are made of an intermetallic compound containing at least one of Al and Mg and have an average particle size of 0.05 μm or more and 1 μm or less. The total area of the particles accounts for 1% by area or more and 20% by area or less. The anticorrosive layer includes a lower sublayer and a surface sublayer on the substrate in this order. The surface sublayer is denser than the lower sublayer. The substrate of the magnesium alloy structural member has high corrosion resistance because of a high Al content. The magnesium alloy structural member has excellent corrosion resistance because of the dense sublayer on the front side of the anticorrosive layer, which prevents a corrosive liquid from reaching the substrate. The porous lower sublayer can reduce the tendency of the anticorrosive layer to detach from the substrate, for example, upon impact and allows the magnesium alloy structural member to retain high corrosion resistance.

    摘要: A magnesium alloy sheet is made of a magnesium alloy containing Al. Particles of an intermetallic compound containing at least one of Al and Mg are present in the sheet in a dispersed state. The sheet includes an oxide film which extends substantially over the surface of the sheet and which has a uniform thickness. The average size of the particles of the intermetallic compound is 0.5 μm or less. The percentage of the total area of the particles is 11% or less. Therefore, the magnesium alloy sheet is excellent corrosion resistance. A magnesium alloy structural member is provided.
