Oxidation behavior of Fe26Cr1Mo stainless steel in the presence of Ni-La_2O_3 electrodeposited composite film

摘要

The oxidation behaviors of Fe26Cr1Mo with and without the Ni-La_2O_3 electrode- posited composite film have been investigated by thermogravimetric analysis(TGA) and a scan- ning electron microscope equipped with an energy-dispersive analytical X-ray system(SEM/ EDAX). The experimental results show that the oxide scale growing on Fe26Cr1Mo exposed at 900deg spalled severely during cooling, while after the stainless steel was coated with the Ni-La_2O_3 electrodeposited composite film, its high temperature cyclic oxidation resistance was significantly improved.
