Corrosion product formed on zinc sample during 2 weeks immersion in saline solution has been investigated. The corrosion layer morphology as well as its chemical composition, was analyzed using scanning electron microscopy (SEM), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). Electrochemical measurement was used to analyze the corrosion behavior. Zinc oxide, zinc hydroxide and zinc hydroxide chloride were formed on zinc surface in saline solution. The thickness of corrosion layer increased with the time increased. The pure Zn has an estimated corrosion rate of 0.063 mm y after immersion for 336 h. Probable mechanisms of zinc corrosion products formation are presented.
对锌样品在盐溶液中浸泡2周期间形成的腐蚀产物进行了研究。使用扫描电子显微镜（SEM）、X射线衍射（XRD）、X射线光电子能谱（XPS）和傅里叶变换红外光谱（FTIR）分析了腐蚀层的形态及其化学成分。采用电化学测量方法分析腐蚀行为。在盐溶液中，锌表面形成了氧化锌、氢氧化锌和氯氧化锌。腐蚀层的厚度随时间增加而增加。纯锌在浸泡336小时后的估计腐蚀速率为0.063毫米/年。文中还提出了锌腐蚀产物形成的可能机制。
