Aluminium alloys have found extensive use in several industrial, biological and dentistry applications, due to their high resistance towards corrosion in certain environments compared with carbon steels. Moreover, this choice is also related to the relatively low cost of the aluminium alloys. The use of aluminium alloys in the biological and dentistry related applications is of special importance. The addition of inhibitors presents an effective method for the reduction of the corrosion of the aluminium alloys in different environments. In this paper, the corrosion of 6063 aluminium alloy in physiological solution, with and without the addition of trihexyltetradecylphosphoniumbis(trifluoromethylsulfonyl) imide has been discussed. The influence of the inhibitor’s concentration on the corrosion rate of the 6063 aluminium alloy in physiological solution at 37°C, was studied using the weight loss and the potentiodynamic polarization techniques. The increase in the concentration of the trihexyltetradecylphosphoniumbis(trifluoromethylsulfonyl) imide added resulted in increased resistance of the 6063 aluminium alloy in the studied corrosion environment.

三己基十四烷基鏻双（三氟甲基磺酰基）酰亚胺作为6063铝合金生理溶液腐蚀抑制剂

与碳钢相比，铝合金在某些环境中具有高耐腐蚀性，因此在多种工业、生物和牙科应用中得到了广泛的应用。而且，这种选择也与铝合金的成本相对较低有关。铝合金在生物和牙科相关应用中的使用具有特别重要的意义。添加抑制剂是一种减少铝合金在不同环境下腐蚀的有效方法。本文讨论了6063铝合金在生理溶液中的腐蚀，添加和不添加三己基十四烷基鏻双（三氟甲基磺酰基）亚胺。使用失重和动电位极化技术研究了抑制剂浓度对 6063 铝合金在 37°C 生理溶液中腐蚀速率的影响。添加的三己基十四烷基鏻双（三氟甲基磺酰基）酰亚胺浓度的增加导致 6063 铝合金在所研究的腐蚀环境中的电阻增加。
