DESCALING AND DECONTAMINATING METHOD FOR METALS
Abstract
Oxide scale is removed from the surface of stainless steels and similar metals by contacting the metal under an inert atmosphere with a dilute sulfuric acid solution containing chromous sulfate. The removed oxide scale is either dissolved or disintegrated into a slurry by the solution. Preferred reagent concentrations are 0.3 to 0.5 M chromous sulfate and 0.4 to 0.6 M sulfuric acid. This process is particularly applicable to decontamination of aqueous homogsneous nuclear reactor systems.
