摘要
用石英晶体微天平 (QCM)测量了在相对湿度 RH为 85％的薄液膜条件下 ,金属 Zn在不同 CO2浓度条件下的腐蚀增质方程 .同时结合红外吸收光谱 (IR)和 X射线能谱 (XEDS)研究了 Zn在薄液膜下的大气腐蚀机理 ,并用扫描电子显微镜 (SEM)对腐蚀产物形貌做了分析 ,阐述了腐蚀产物的形成特征及对基体金属的保护特性 .
The corrosion gain weight of electroplated zinc in atmosphere containing different concentrations of CO2 under thin electrolyte film were measured by means of quartz crystal microbalance. Equations of corrosion gain weight were derived from the experiments under the same condition. Atmospheric corrosion mechanism of zinc under thin electrolyte film was also discussed by the equation of corrosion gain weight, combined with Infrared absorption spectroscopy and X-ray energy dispersion spectroscopy. Protective features was elucidated by analysis of the morphology of atmospheric corrosion layer on zinc using SEM.
