A new type of steel containing Sb based on the CASTRIP process had been designed to improve the corrosion resistance of high-strength steels in industrial atmospheres.The properties of the electrochemistry and rust layer(RL)were analyzed to evaluate the corrosion resistance of the ultra-thin cast strip(UCS)steel containing 0.10%Sb.Experimental results showed that the corrosion resistance of UCS steel containing Sb was doubled compared to that of traditional hot rolling strip(HRS)steel.It could be interpreted as an integral effect of CASTRIP process and alloying elements.The optimization for microstructure and inclusion of UCS steel can reduce the localized corrosion effects in initial corrosion processes.Cu,P and Sb reduced the anodic reaction and CuFeO2/Cu2O,CuO,FePO4 and Sb2O3 were formed,promoting the transition fromγ-FeOOH toα-FeOOH.A(Cu,Sb,P)-enriched inner RL was generated and significantly improved protective ability of the RL. 展开更多
