"就是Zn和钢形成的电池效应，galvanic reaction. "的英语翻译
【 中文 】
就是Zn和钢形成的电池效应，galvanic reaction. 涂层时，Zn作为易失掉电子的阳极，还原附着到钢的表面。因为没有介质的存在，Zn和钢就没有发生电化学反应。但是在Zn离子再打磨后离开了钢的表面，这时有雾气，雨水及有液体作为介质，Zn立刻就和刚表面建立了电池的正负极，Zn离子再次丧失电子还原，表面被浊失，凸凹不平。
【 英语 】
It is the battery effect formed by zinc and steel. When coated with galvanic reaction, zinc acts as an anode that easily loses electrons and is reduced to adhere to the surface of steel. Because there is no medium, there is no electrochemical reaction between zinc and steel. But after the zinc ion is grinded again, it leaves the surface of the steel. At this time, fog, rain and liquid are used as the medium. The positive and negative electrodes of the battery are immediately established between the zinc ion and the rigid surface. The zinc ion loses the electron reduction again, and the surface is cloudy and uneven.
