ANTI-CORROSION COATING FILM STRUCTURE, METALLIC MEMBER EQUIPPED WITH SAME, ANTI-CORROSION TREATMENT METHOD, AND SURFACE-TREATING AGENT

摘要

An anti-corrosion coating film structure having such a structure that an intermediate layer and a silane coupling layer are laminated in this order on the surface of a metal base material is formed. The intermediate layer is formed of an oxide or hydroxide of at least one metal selected from the group consisting of Ce, La and Y. It is desirable that the intermediate layer contains at least one element selected from the group consisting of Mo, W and V. Thus, it becomes possible to provide a surface having high corrosion resistance and excellent heat resistance, solvent resistance and sliding properties.
