Abstract By means of accelerated corrosion tests and electrochemical measurements,the influence of NaHSO3, NaCl or NaHSO3+NaCl on corrosio behavior of zinc was studied.Its corrosion products were analysed by XRD,and corrosion mechanism of zinc with emphasis on the mixed medium (NaHSO3+NaCl) was discussed.The corrosion process of zinc in Shenyang atmosphere could be simulated by intermittent fogging spraying testing with 10-1mol/L NaHSO3 +10-2 mol/L NaCl.The relationship between weight loss of zinc and test duration could be described by a formula △W=A+Bt.

Key words: Zinc atmospheric corrosion accelerated corrosion test
