摘要： A method produces a dust core by molding a mixture through compression molding to give a powder compact, the mixture containing an oxygen-source-releasable compound and an iron-based soft magnetic powder for powder compacts including an iron-based soft magnetic matrix powder and an insulating coating film present on the surface of the matrix powder; and heating the powder compact to oxidize at least the surface of the iron-based soft magnetic matrix powder by the action of the oxygen-source-releasable compound. The resulting dust core excels not only in mechanical strength but also in resistivity (insulation).

摘要： Disclosed is a surface-treated metal material which includes a metallic base including a steel or aluminum material; and an anti-corrosive layer present covering at least one surface of the metallic base. The anti-corrosive layer contains 0.001 to 1 g/m2 of one or more substances selected from the group consisting of benzoic acid salts, glutamic acid salts, anisidines, glycine, and quinolinols. The benzoic acid salts and/or glutamic acid salts are preferably chosen from potassium salt, sodium salt and ammonium salt. Also disclosed is a joined article of dissimilar materials including the surface-treated metal material as at least one of the materials. The surface-treated metal material includes, as the base metal, a steel or aluminum material and is thereby effectively and inexpensively protected from galvanic corrosion without performing electrical insulation or complete atmospheric isolation.
