Research Progress of Alloy Corrosion in Supercritical Water Oxidation Condition

Supercritical water oxidation (SCWO) is a new technology which can safely,economically and effectively destroy various organic wastes.The operational principle and process of SCWO are described,corrosion of several alloys in SCWO condition is introduced.It is showed that the corrosion resistance of nickel alloy treated with grain boundary engineering is better than other alloys.
