电镀锡板表面的腐蚀性在很大程度上取决于其表面的化学处理覆膜、表面氧化覆膜,或者表面锡层的电着状态及腐蚀液的种类等等。持这种观点的作者们用脉冲极化仪研究表面处理覆膜或氧化覆膜对耐蚀性的影响,进而用阴极极化曲线研究镀锡板表面的电着状态以及腐蚀溶液中含有的两、三种氧化剂对腐蚀性的影响。 Electrodeposited tin surface corrosion depends largely on the surface of the chemical treatment coating, the surface oxide film, or the surface of the tin layer of the state of electricity and the type of corrosion solution and so on. The authors who hold this view use pulsed polarizers to study the effect of the surface treatment coating or oxide coating on the corrosion resistance and then use the cathodic polarization curve to study the electrical state of the surface of the tinplate and the presence of two , Three kinds of oxidants on the corrosive effect.
