Title:
MULTILAYER FILM LAMINATE USING ALUMINUM OR ALUMINUM ALLOY AS SUBSTRATE, AND LAMINATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/105392
Kind Code:
A1
Abstract:
Disclosed is a multilayer film lamination method, by which an amorphous carbon film can be formed at the top of an aluminum or aluminum alloy base with high adhesion and corrosion of a layer below the amorphous carbon film can be suppressed. Specifically, a multilayer film structure with an adequate gradient of hardness can be obtained by forming a zinc substituted film on the surface of a base that is composed of aluminum or an aluminum alloy, forming a nickel plating layer by an electroless plating method using the zinc substituted film as a primer layer, then forming a hard chromium plating layer, and additionally forming, as the uppermost layer, an amorphous carbon film preferably at a temperature of 350˚C or less and preferably by a low-temperature plasma CVD method.
