Abstract The corrosion behavior of pure chromium with a solid NaCl deposit on itssurface has been investigated in air or oxygen containing water vapor at500–700°C. Results indicated that, when pure Cr was corroded inair or in oxygen plus water vapor, the corrosion was restrained even at700°C because of the formation of a compact and uniform Cr2O3protective scale. However, a solid NaCl deposit on its surface acceleratedthe corrosion of pure Cr in air or in oxygen plus water vaporsignificantly. A model of synergistic action to explain the effect of solidNaCl with oxygen and/or water vapor and on the corrosion of pure Cr isproposed.
