Abstract

PURPOSE:To provide a method of applying anti-corrosive treatment on atinned tube, capable of protecting the surface of a finned tube with aluminum fins for long from corrosion, which comprises the steps of forming aluminum film on the surface of a tube made of iron or the like, then forming a film of chromate over the aluminum film, and further foriming a film of mineral substance over the surface of said chromate film.
