国产铁基牺牲阳极在冷却器上的应用

Application of Iron-base Sacrificial Anode Made in China on Cooler

依据阴极保护的理论分析了铁基牺牲阳极保护铜冷却器的可行性;收集了几种典型的国产铁基牺牲阳极材料与俄罗斯的铁基牺牲阳极材料进行了室内电化学保护性能对比,并且选取了国产Q235B材质的铁基牺牲阳极与俄罗斯的CT3nc材质铁基牺牲阳极,在实船冷却器上进行了对比应用试验。结果表明,国产铁基牺牲阳极材料的电化学性能与俄罗斯的阳极材料相当,工作电位处于船用铜合金的保护电位范围,电流效率略高于俄罗斯铁基牺牲阳极;实船试验选用的国产Q235B材质铁基牺牲阳极,其活化性能略优于俄罗斯的CT3nc材质铁基牺牲阳极,其保护期效远长于传统的锌合金牺牲阳极。

The feasibility of copper coolers protected by the iron-base sacrificial anode was analyzed by the cathodic protection theory. The electrochemical protection property and practical application were compared between some typical homemade iron-base sacrificial anodes and the anodes made in Russian. The results showed that the materials made in China were similar to the material imported from Russia. When the working potential was above the protective potential, the efficiency of homemade anodes was higher than that of Russian. And the current efficiency of homemade Q235 sacrificial anode was also higher than that of CT3nc sacrificial anode made in Russia in the practical use. The protection persistence was longer than that of traditional zinc alloy saerificial anode.
