Cyclic voltammetry and potentiodynamic polarization techniques were used to study the effects of 4-[4-(1,3-benzothiazol-2yl)phenoxy] phthalonitrile (BT) and tetrakis[(benzo[d]thiazol-2ylphenoxy) phthalocyaninato] gallium(III)chloride (ClGaBTPc) as aluminium corrosion inhibitors in 1.0 M hydrochloric acid. The presence of the inhibitors in the concentration range of 2 to 10 μM was found to retard the aluminium corrosion process such that the inhibition efficiency was found to range from 28.2 to 76.1% for BT and from 71.5 to 82.7% for ClGaBTPc. The latter was a better inhibitor. Scanning electron microscopy and energy-dispersive X-ray measurements reveal effective metal surface protection by the inhibitors, most probably by shielding it from the corrosion attacks of Cl⁻ from the acid. The calculated quantum chemical parameters agreed with experimental results.

循环伏安法和电位动力学极化技术用于研究4- [4-（1,3-苯并噻唑-2基）苯氧基]邻苯二甲腈（BT）和四[[苯并[d]噻唑-2基苯氧基]对苯二甲腈]镓（III）的作用氯化物（ClGaBTPc）在1.0 M盐酸中作为铝腐蚀抑制剂。发现浓度在2至10μM范围内的抑制剂可延缓铝腐蚀过程，因此对BT的抑制效率范围为28.2至76.1％，对于ClGaBTPc的抑制效率范围为71.5至82.7％。后者是更好的抑制剂。扫描电子显微镜和能量分散型X射线测量由抑制剂揭示有效金属表面的保护，最可能是由选自Cl的腐蚀攻击屏蔽它^-从酸。计算出的量子化学参数与实验结果吻合。
