摘要

The effect of Cr content in steel on its passivation behavior in a CO₂ aqueous environment containing silty sand was investigated. The results indicated that the stability of passive film was improved with increasing Cr content. High Fe₃C content accelerated the rapid formation of a passive film as well as precipitates and dislocations. Increasing Cr content enhanced the contents of Cr₂O₃ and Cr(OH)₃ in the passive film. Silty sand increased carrier densities of passive films, thereby reducing their protective effects. The role of the contents of Fe₃C and Cr on corrosion mechanism of Cr steel with silty sand was emphasized.
