统编化学教材中关于金属的电化腐蚀部分,它与工业生产,生活实际联系紧密。这里介绍一些有关电化腐蚀的原理和影响腐蚀速度的主要因素,作为学生课外参考资料。一、金属电化腐蚀的原理金属的腐蚀是自发进行的,迄今我们仍无法使它完全消除。但是,如果我们掌握了金属发生腐蚀的规律,就能够延缓腐蚀过程,减轻腐蚀的程度。
The galvanic corrosion part of the metal in the textbook is compiled, and it is closely related to industrial production and life. Here are some of the principles of galvanic corrosion and the main factors affecting the rate of corrosion as a reference for students. First, the principle of metal galvanic corrosion Metal corrosion is spontaneous, so far we can not completely eliminate it. However, if we master the law of metal corrosion, we can delay the corrosion process and reduce the degree of corrosion.
