CORROSION-RESISTANT STRUCTURE AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To make it possible to provide excellent corrosion resistance and wear resistance in a molten salt treating facility. SOLUTION: This corrosion-resistant structure comprises forming an alumina film 12 as a substrate layer on the surface of a base material 11 as required, and then forming a polyimide resin film 13 as an imide resin layer wherein a pigment (Al1 O3 ) is dispersed as a first layer on the surface of the film 12 and an alumina film 14 as a ceramic layer as a second layer on the surface of the film 13 to form a multilayer film 15.
