铝合金表面BTSE硅烷化处理研究
, PP. 1189-1194
Keywords: 硅烷化处理,BTSE,LY12铝合金
Abstract:
通过极化曲线与电化学阻抗谱(EIS)等技术对LY12铝合金表面形成的BTSE硅烷膜在NaCl溶液中的性能进行了研究.结果表明,硅烷膜的存在,一方面很大程度上增大了铝合金的耐蚀性,另一方面并不影响合金电极在腐蚀介质中的电极动力学.这意味着BTSE膜对侵蚀粒子仅起到阻挡层的作用.提出了硅烷化试样在测试溶液中的合理等效电路,并对EIS数据进行了拟合.采用正交设计方法对硅烷化工艺参数进行了优化,其中采用电极体系的极化电阻(由EIS拟合得出)来量化硅烷膜的耐蚀性.文中还对各因素对膜性能的影响规律进行了初步探讨.
