摘要：

This work reports a preliminary exploration of the potential of the ionic liquid trihexyl(tetradecyl) phosphonium bis(2,4,4-trimethylpentyl)phosphinate (P(6,6,6,14)M(3)PPh) for use as a conversion coating agent for corrosion protection of magnesium alloy AZ31. Results obtained for the as received IL did not indicate any measureable improvement in protection. However, when the IL was allowed to reach equilibrium/saturation with moisture from the atmosphere, treatment with this 'wet' solution resulted in a substantial improvement in corrosion resistance. Preliminary electrochemical, optical, and spectroscopic characterization of the film will be presented along with a possible mechanism for film formation.
