Rostschutzbehandelter metallischer Grundwerkstoff und Verfahren zur Rostschutzbehandlung der Oberfläche eines metallischen Grundwerkstoffs

摘要

In an antirust treated metal base material in accordance with the present invention, a coating film containing insulating polyaniline in a highly oxidized state (PE state) is formed on the surface of a metal base material. A method for antirust treatment of the surface of a metal base material includes a process of forming a coating film containing insulating polyaniline in a highly oxidized state (PE state) on the metal base material surface. According to the present invention, an antirust treated metal base material, in which the coating film of an insulating polyaniline system containing no dopants exhibits strong corrosion inhibition effect, and a method of antirust treatment for the metal base material are provided.
