ABSTRACT:
A method for forming a fluororesin film on a metallic substrate is described, which method comprising forming a chromium oxide film on at least one side of a metallic substrate and then forming a fluororesin film on the chromium oxide film. By this, good adhesion of the fluororesin film to the substrate is ensured. Further, when the fluororesin film is degraded, the film is readily removed without damaging the substrate and a fresh fluororesin film can be again formed on the substrate through a fresh chromium oxide film so that the substrate keeps it original dimensional precision and may be used semi-permanently.
