Abstract The effect of NaCl deposit on the corrosion behavior of CuCr alloy at 700℃~900℃ was studied by means of metalloscope,XRD,SEM/EDX and thermogravimety.Results indicated that CuCr alloy coated with NaCl deposit suffered from seriously corrosion than in single air; the corrosion production was loose and easy to scale off; and Cr phase was easier to be eroded than Cu phase,and chromium depletion is developed in the matrix of alloy beneath the corrosion region.Effect of deformation on the corrosion of the CuCr alloy were discussed,and acceleration mechanisms of NaCl on the corrosion of CuCr alloy were also discussed.
