摘　　要：The effect of the presence of Ni in solution as Ni-EDTA complex in lithiated water at roon temperature and pH 10.5 on the formation of ferrite coating on carbon steel surface was studie in an autoclave at 523 K for 12 days at different Ni concentrations with varying amounts of free EDTA. The Ni-ferrite coating was characterized by XRD, SIMS and XPS and also bulk chemical analysis by AAS and UV-visible spectrophotometer. The chemical composition of Ni-ferrite coating showed variation with depth acro5s solution-oxide interface to oxide-metal interface.The content of Ni in the oxide coating on the surface near solution-oxide intedece was found to be higher than the average Ni content estimated by analysis after descaling the coatingThe effect of the presence of Ni in solution as Ni-EDTA complex in lithiated water at roon temperature and pH 10.5 on the formation of ferrite coating on carbon steel surface was studie in an autoclave at 523 K for 12 days at different Ni concentrations with varying amounts of free EDTA.
