Abstract
With the deepening of Accident Tolerant Fuel(ATF)research and the development of new materials,FeCrAl is attracting attention due to its high strength,excellent deformability,high temperature oxidation resistance,and the corrosion resistance of FeCrAl cladding directly affects the safety and performance of fuel cores.In this regard,this paper analyzes the corrosion behavior of FeCrAl from its corrosion behavior mechanism,through the oxidation kinetics,corrosion process and influencing factors,in order to provide a reference for the corrosion study of FeCrAl in light water reactors.The investigation results show that there are differences in the corrosion resistance mechanisms of Cr and Al elements in FeCrAl alloys.The corrosion of FeCrAl alloys is complex under different oxidation media and temperatures,accompanied by the formation of single or multiple layers of oxides with different composition and morphology.关键词
