Abstract: 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.
