✦ Synopsis

In order to improve the corrosion resistance of magnesium alloys, plasma immersion ion implantation and oxidation has been employed using water plasma sustained by an inductively coupled radio-frequency plasma source. After the treatment, the corrosion behavior of the samples is evaluated using potentiodynamic polarization tests. The film structure and depth profile of oxygen are characterized using XRD and RBS. The results demonstrate that water plasma implantation can effectively facilitate oxidation and improve the corrosion resistance of magnesium alloys. Our results also indicate that lower temperature processing is preferred to achieve better corrosion resistance.

Titanium alloy, Ti6Al4V, is widely used in dental and orthopedic implants. Despite its excellent biocompatibility, Ti6Al4V releases toxic Al and V ions into the surrounding tissue after implantation. In addition, the elastic modulus of Ti6Al4V ($110 GPa) is significantly higher than that of bone (10
