Abstract

Magnesium alloys are attractive materials for the biomedical applications, due to the excellent biocompatibility. However, these alloys show rapid corrosion rates in the body that limits their clinical applications. Low toxic ionic liquid (IL) trimethyl(butyl)phosphonium diphenyl phosphate P1444DPP have been investigated to provide corrosion protection for magnesium alloy AZ31 in simulated body fluids (SBFs). This work reports a preliminary exploration of the influence of various treatment temperatures on the corrosion protection properties of IL films for the magnesium alloy AZ31 in SBF. Results show that the IL treatment at room temperature did not bring significant improvement in the corrosion performance of the AZ31 in SBF. However, when the treatment temperature was increased to 75°C, the IL treatment resulted in a substantial reduction of the corrosion of the AZ31 in SBF. The influence of ionic liquid treatment on the corrosion performance of the magnesium alloys AZ31 in the SBF has been investigated by electrochemical impedance spectroscopy (EIS) tests and the observation of surface morphology.
