大气腐蚀监测Cu-Zn探针环境因素敏感性和腐蚀影响
Environmental Factor Sensitivity and Corrosion Effect of Cu-Zn Probe for Atmospheric Corrosion Monitoring
【摘要】 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,CuZn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。
【Abstract】 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 solutions,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 sensitivity.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.
