Abstract

PURPOSE:To improve corrosion resistance and lubricity by providing a film of specific metal or its alloy and a film of fluororesin on a ferromagnetic thin metallic film. CONSTITUTION:On a nonmagnetic material base, a ferromagnetic thin metallic film of Co or Co alloy is formed and on the surface, a film of metal selected among Cr, Ni, Ti, Nb, Ta, Al, Au, Ag, and Pt or alloy containing the metal is formed by vapor deposition to a 100-2,000Angstrom ngstrom thickness. On the surface, a film of fluororesin produced by the polymerization of polytetrafluoroethylene and other olefin monomers is further formed by plasma polymerization to a 100-3,000Angstrom ngstrom thickness.
