摘要： PROBLEM TO BE SOLVED: To provide a method for inexpensively producing a heavy duty coated steel with good productivity to meet the requirement of long service life.
SOLUTION: The method comprises depositing a thin film of an inorganic oxide or corrosion resistant metal in or on the inside or surface of a heavy duty corrosion-proof coating, for example, stacking a deposited organic resin film on a conventional heavy duty corrosion-proof coating or that coating performing a chemical treatment on its underlayer through an adhesive. The deposited inorganic layer is preferably 10-1,000 nm in thickness. The penetration of oxygen and water from above the coating are prevented to inhibit the breaking of an adhesion interface, and thus the progress of adhesion deterioration from the coating end or flaw can be restrained. Further, the effect of sustaining the above inhibition is greater than that of the organic material film. Accordingly, the corrosion-proof coating higher in reliability than heretofore can be provided.
