PROBLEM TO BE SOLVED: To provide a corrosion-resistant Al structural member provided with a non-polluting corrosion-protective coating containing no hexavalent chromium. SOLUTION: The corrosion-resistant Al structural member 1 has an underlayer 2 adhering to the surface of the Al structural member 1 O , and the corrosion-protective coating 3 adhering to the surface of the underlayer 2. The underlayer 2 includes Zn, and the corrosion-protective coating 3 includes a chromated film containing trivalent Cr for Zn. COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To provide a vertical magnetic recording medium that has noise characteristics lower, than when using a Permalloy (R) series or sendust group crystalline materials and a very flat soft magnetic lining layer, and is capable of high-density recording, and provide a magnetic recording device using it, and to provide a manufacturing method and machine for the vertical magnetic recording medium. SOLUTION: This vertical magnetic recording medium 1 has a soft magnetic lining layer 3, a vertical recording layer 4 consisting of a ferromagnetic material, and a protective layer 5, all being laminated on a base 2. The soft magnetic lining layer 3 is composed of a soft magnetic material of FeSiAlN film, and the FeSiAlN film can change the atom% of Fe, Si, Al, and N, by changing the amount of N 2 gas in the mixture gas containing N 2 and Ar gas supplied into the chamber.

摘要:
PURPOSE:To provide an excellent waterproof effect by projecting an iron-zinc blast material to the surface of iron (alloy to form a zinc coating film and subjecting further the surface to a nonaqueous chromate treatment. CONSTITUTION:The blast material consisting of the assemblage of the indepen dent particles formed by using the iron (alloy) as a nucleus and depositing zinc (alloy) via an iron zinc alloy layer around the same is projected to the surface of the iron or iron alloy to form the zinc coating film. The coated surface is subjected to the nonaqueous chromate treatment. Hydrocarbon contg. chlorine and fluorine of several 1-2 C, for example, trichloroethylene, trichlorotrifluoroethane, etc., are used for the org. solvent to be used for the nonaqueous chromate treatment. This method is the nonaqueous treatment and does not require a measure for waste water treatment. The highly corrosion resistant film is thus inexpensively formed.
