探讨了Cu-Zn探头在不同温度、NaCl浓度、NaHSO3浓度以及NaCl和NaHSO3混合溶液的盐雾环境下的腐蚀行为,以及Cu-Zn探头积分电量的变化规律.研究结果表明,Cu-Zn探头对温度、NaCl浓度、NaHSO3浓度以及二者混合体系浓度的变化具有高度敏感性,表现出较为显著的灵敏度.在综合考虑各因素的基础上,Cu-Zn探头的腐蚀影响顺序为:温度<NaCl浓度<NaHSO3浓度<NaCl和NaHSO3混合浓度.
Environmental Factor Sensitivity and Corrosion Effect of Cu-Zn Probe for Atmospheric Corrosion Monitoring
The corrosion behavior of Cu-Zn probe,used for atmospheric corrosion monitoring(ACM),was studied at different temperatures via salt spray testing with NaCl solutions,NaHSO3 solu-tions,and NaCl and NaHSO3 mixed solutions of varying concentration respectively.Correspondingly,the variation of the integrated charge quantity of Cu-Zn probes was also acquired with the testing conditions.The results indicate that the Cu-Zn probe is highly sensitive to the variation of test temperature,NaCl concentration,NaHSO3 concentration,and the concentration of the mixed ones,exhibiting significant sen-sitivity.On the basis of comprehensive consideration of various factors,the order of corrosion impact for Cu-Zn probes is as follows:temperature<NaCl concentration<NaHSO3 concentration<concentration of NaCl and NaHSO3 mixture.
