Abstract
Disclosed is a corrosion-resistant film for protecting the surfaces of Ag, which comprises an Ag--Mg alloy having an Mg content of from 1 to 10 atomic % and which is applied to an Ag substrate. Also disclosed is a corrosion-resistant composite structure composed of an Ag substrate and a protective film of an Ag--Mg alloy with an Mg content of from 1 to 10 atomic % formed on the surface of the Ag substrate. The corrosion-resistant film protects an Ag with a silver-white gloss from being blackened by sulfide components, etc. The adhesiveness between the film and the Ag substrate is good. The composite structure has a high reflectivity and is useful as a reflective film for photo-magnetic recording media, optical recording media, reflectors, illuminators, etc. The surface of the corrosion-resisting film is oxidized to form an MgO layer on the film, and the film exhibits a high protecting effect.
