Abstract The effect of chemical pre-passivation and subsequent vacuum steam treatment on passive characteristics of stainless steels has been studied. Vacuum steam treatment promotes the passive film formation of the steels,and this process can be further improved by chemical prepassivity.The passive film stability of the steel treated by the new technique is much higher than that of the steel treated by classical un- vacuum steam treatment technique,its stable time at passive potential is almost 50 times as that of 0Cr18Ni19Ti and its passive current density is at least one order lower than that of 0Cr18Ni19Ti the pitting corrosion resistance in Cl~- medium is also improved a lot as compared with that of its original state.X-ray surface analysis has been used to discuss the mechanism of improving corrosion resistance by the new technique.
