Abstract The corrosion rate of the phosphorusbearing steel was measured by dry/wet alternate immersion test. The formed rust layer was studied by of XRD、SEM and polarization test. The results showed that adding RE in the phosphorusbearing steel is able to improve corrosion resistance of the steel.due to formation of compound deposited on anode from Ce3+、Ce4+ and La3+ ions and PO43-、H2PO4-、SO42-.

Key words： atmospheric corrosion P RE
