【摘 要】

：

5083铝合金作为铝镁系的合金,由于具有高的强度比、耐蚀性和良好的塑性,在汽车、海洋和工业领域得到了广泛应用.5083铝合金中含有多种金属第二相成分,改善了基体的力学性能,同时也更易于形成局部腐蚀[1].针对5083铝合金的局部腐蚀,我们研究了在3.5％NaCl溶液中采用掺杂缓蚀剂阴离子的聚吡咯来修复铝合金的点蚀[2].当铝合金发生腐蚀,聚吡咯得电子并脱掺杂释放出缓蚀剂阴离子,抑制铝合金表面进一步

电化学技术在搪瓷钢开发中的典型应用

搪瓷钢在轻工、家电、冶金、化工、建筑等方面有着广泛的应用,从厨房用具、卫生洁具,到建筑饰面板、化工反应罐等等,都是用各种搪瓷钢钢制造而成的[1].鳞爆是搪瓷钢涂搪过程中比较常见的缺陷之一,在搪瓷钢开发过程中必须使其抗鳞爆性能达到一定要求.电化学技术是一种无损检测技术,具有响应迅速,重复性高,试验周期短,试验用样少等特点,因此在产品开发方面可以发挥重要作用[2].
