饮料用金属罐腐蚀原位检测技术

摘要

An in-situ determination method for determination of tinplate beverage can basing on electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) was studied.It was found that the metal corrosion can be detected by EIS and EN through time constants and transient peaks of current noise,respectively.The method in this work can be successfully applied to in-situ detect the tinplate beverage can.%通过电化学交流阻测试和电化学噪声测试开发了一种原位检测饮料用金属罐腐蚀状态的技术方法.实验表明,EIS和EN测试分别通过时间常数和电流噪声暂态峰数量反映了金属腐蚀状态.该方法可用于饮料用金属罐腐蚀的原位检测.
