天然水中的氯离子含量由几mg/L(淡水)至几万mg/L(海水)变化很大。其含量之高低对金属腐蚀过程的影响是大家都关切而又是有争议的问题。有人认为氯离子含量越高,金属腐蚀越迅速。为此要求工业冷却水中的氯离子越少越好。甚至到了见氯生畏的地步。有的认为氯离子并不直接参加腐蚀电极过程,但它容易变形极化,优先吸附在金属表面,能强烈地催化腐蚀过程。另一种看法认为金属腐蚀过程是各种因素综合作用的
Chlorine ion content in natural water from a few mg / L (fresh water) to tens of thousands of mg / L (sea water) vary greatly. The level of its impact on the metal corrosion process is a matter of concern and controversial issue. Some people think that the higher the chloride ion content, the more rapid metal corrosion. For this reason, the less chlorine ion in industrial cooling water is, the better. Even to the point where chlorine scared. Some believe that chloride ions do not directly participate in the process of corrosion of the electrode, but it is easy to deform and polarize, preferentially adsorbed on the metal surface and strongly catalyze the corrosion process. Another view that the metal corrosion process is a combination of various factors
