A new ionic liquid, benzyl triphenyl phosphonium bis(trifluoromethylsulfonyl)amide ([BPP][NTf₂]), for magnesium alloy is synthesized. The potential of [BPP][NTf₂] to be inhibitor is firstly estimated as compared with [P_6,6,6,14][NTf₂] by theoretical calculations. Then, the inhibition of AZ31B Mg alloy in 0.05 wt% NaCl solution is evaluated by [BPP][NTf₂] is investigated by Tafel linear polarization method, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). The most optimum inhibitor efficiency of [BPP][NTf₂] is 91.4% at room temperature. The adsorption of [BPP][NTf₂] on the surface of AZ31B Mg alloy obeys Langmuir isotherm with predominantly chemical adsorption. The corresponding result is further analyzed by the theory. The corrosive product is detected by Fourier transform infrared spectrum (FTIR). The possible inhibition mechanism is proposed, in which the effect of cation on inhibition is proposed in addition to the influence of anion.
