Study on Properties of FeCrAl Coated ATF Zirconium Cladding Prepared by Plasma Spry

This paper introduces the latest accident tolerant fuel (ATF) cladding achievements of China General Nuclear Power Corporation (CGN). The FeCrAl coating of zirconium with different technology were prepared by plasma spay. From the SEM and XRD results, the best technology for FeCrAl coating sample can be selected. The corrosion resistance of FeCrAl coating is tested by the high temperature steam oxidation test, and the element distribution in oxidated sample is analyzed by SEM and EDS, to study the corrosion mechanism of FeCrAl coating, and the improvement method is suggested.
