摘要

采用自由测试法测定了铝合金分别与Q 235钢、镀锌铁片和铜片三种不同材料组成的电偶在3.5%N aC l水溶液中的电偶电流、腐蚀电位和腐蚀速度.研究了加速铝合金电偶腐蚀的因素.结果表明

铝合金在含有氯离子的溶液中腐蚀较严重;并且偶合材料、阴阳极面积比对铝合金的电偶腐蚀有重要影响.

Abstract

The galvanic corrosion of aluminum alloy coupled with different materials

including Q_235 steel

zinc-coated iron plate

copper plate

was studied by free running test in 3.5% NaCl solution.In this study

galvanic current

corrosion potential and corrosion rate were measured.The results showed that: aluminum alloy was corroded serious in solution with chlorine ions;moreover

coupling material and area ratio of cathode to anode were important effects on the galvanic corrosion of aluminum alloy.
