通过间歇式盐水喷雾试验和极化曲线测定，对比研究了NaHSO3、NaCl和NaHSO3+NaCl三种介质对锌腐蚀的影响，并对腐蚀产物进行了XRD分析。实验结果表明，以10-1mol/L NaHSO3+10-2mol/L NaCl为加速剂，采用间歇式喷雾试验，可模拟锌在沈阳污染大气中的腐蚀过程，腐蚀规律可用△W=A+Bt公式描述。
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.
