磁场作用下铜材在海洋大气中的腐蚀行为
Corrosion Behavior of Copper Materials in Marine Atmosphere under Action of Magnetic Field
摘 要
通过腐蚀速率计算，电化学测试，扫描电镜和X射线衍射分析，研究了磁场对黄铜、紫铜、青铜和铍铜在海洋大气中的腐蚀行为的影响。结果表明：外加磁场加速了铜材在海洋大气中的腐蚀，但并未影响铜材表面腐蚀产物的物相；铜材的主要腐蚀产物为CuCl2、Cu2O、CuSO4·3Cu （OH）2·2H2O和CuCl2·3Cu （OH）2，除此以外黄铜的腐蚀产物中还有ZnCl2，而铍铜的腐蚀产物中有少量Al2O3。

Abstract
The effect of magnetic field on the corrosion behavior of brass, pure copper, bronze and beryllium copper in marine atmosphere was studied by corrosion rate calculation, electrochemical testing, scanning electron microscopy and X-ray diffraction analysis. The results show that the external magnetic field accelerated the corrosion of copper materials in marine atmosphere, but did not affect the phases of corrosion products on the surface of copper materials. The main corrosion products of copper materials were CuCl2, Cu2O, CuSO4·3Cu(OH)2·2H2O and CuCl2·3Cu(OH)2. In addition, ZnCl2 was found in the corrosion products of brass, and a small amount of Al2O3 was found in the corrosion products of beryllium copper.
