| 摘 要： | 目前有关热浸镀铝层在海水中形成的初级腐蚀产物Al（OH）3对镀层后续腐蚀影响的研究较少。向海水中添加Al（OH）3使其饱和，将Q235钢稀土铝热浸镀试样浸入其中，采用失重法、扫描电镜（SEM）、极化曲线和交流阻抗谱研究了海水中Al（OH）3对稀土铝热浸镀层腐蚀行为的影响。结果表明：热浸镀试样在添加了Al（OH）3的海水...

| Abstract: | Al(OH)3 was added into seawater to form a saturated solution,and then Q235 steel coated with hotdipped rare earth-Al(RE-Al)coating was immersed into the resultant seawater.The corrosion behavior of the coating was investigated based on weight loss tests,scanning electron microscopic observation and electrochemical tests(polarization curve and electrochemical impedance spectroscopy).It was found that hotdipped RE-Al coating had a higher corrosive rate and experienced severer surface corrosion in seawater con... |
