Abstract
采用静态失重法、动电位极化曲线法、电化学交流阻抗法、扫描电镜和X射线光电子能谱等方法, 研究了在质量分数为17%(0.534mol/L)的四丁基溴化铵(TBAB)溶液中, 苯并三氮唑(BTA)和Na_3PO_4(SP)单独和复配使用对锌腐蚀的抑制作用.结果表明, BTA和Na_3PO_4及其复配物对TBAB溶液中的锌具有缓蚀作用, BTA和Na_3PO_4对锌的缓蚀效率随缓蚀剂质量浓度的增大而提高; 0.1 g/L的BTA和1 g/L的Na_3PO_4的复配物的缓蚀效率高于93%.文中还结合扫描电镜和X射线光电子能谱的结果对复配物的缓蚀机理进行了讨论, 二者的协同效应在于Na_3PO_4在锌的表面形成含有ZnO、Zn(OH)_2和 Zn_3(PO4)_2的保护层, BTA吸附在该保护层的表面或者是镶嵌在保护层的内
