Abstract Themogravimetric studies have been conducted on the corrosion behavior of pure chromium coated with NaCl deposit in air or oxygen containing water vapor at 500-700℃.Results indicated that in air or in oxygen plus water vapor, the weight gain of Cr sample was not detectable even at 700℃ due to the formation of a compact and uniform Cr2O3 protective scale. However, with a solid NaCl deposit on its surface, corrosion of pure Cr in the same environments was significantly accelerated because of the reaction of NaCl with the oxide and substrate metal. When testing temperature increased and approached the melting temperature of NaCl, the corrosion of pure Cr coated with NaCl in air or in oxygen plus water vapor became more severe. A mechanism to explain the syneigistic effect of water vapor and NaCl on the corrosion of pure Cr is proposed.

Key words: pure Cr NaCl water vapor synergistic effects corrosion
