| 摘 要： | 循环冷却水处理是工业生产中的一个重要环节。臭氧作为单一的水质稳定剂在循环冷却水中具有缓蚀作用。研究结果表明：吸附在金属表面的臭氧使金属表面从活化腐蚀状态转变为钝化状态，使金属腐蚀电位由活化电位区跃变到钝化电位区，阻止金属的溶解；同时氧的传质速率加快，也可以降低由于浓差极化所产生的腐蚀作用；对于未经预膜处理的金属，臭氧改变金属表面状态，形成一层氧化钝化膜，从而起到了缓蚀作用。

| Abstract: | The treatment of circulating cooling water is important for industrial production.Ozone as a sole stabilizer for circulating cooling water has an inhibitive effect.The experimental results indicate that ozone adsorbed on metal surface can change metal surface from activated corrosion state into passivation state,and make metal corrosion electrode potential turn from activation electrode potential region to passivation electrode potential region, that prevents the dissolution of metal;at the same time,the increasing of oxygen transfer rate can reduce the corrosion made by concentration polarization;for the metal with no pre-filming treatment,ozone can change the surface state of metal and make a passivation layer which has an inhibitive effect. |
