Abstract
Magnesium (Mg) and its alloys are third-generation biomedical implant material in the biomedical field. The limitation of using Mg in medical applications is its rapid corrosion rate. In the present work, for the first time, AZ91 magnesium alloy surface treated with the inductively coupled Ar/O2 Plasma process to decrease the corrosion rate of the alloy. The oxidation mechanism and surface analysis have been investigated in detail. The electrochemical studies in SBF solution reveal that plasma modified surface increases the corrosion resistance of the alloy compared to the untreated surface.
