Study of the Biocompatibility of Ti6Al4V Medical Alloys

Abstract

In this study, nitriding with plasma (using nitrogen gas) was used as a method to treat the surface of titanium alloy (Ti6Al4V) for different time periods (5-10-15-20 hours), and the measurements showed that nitrogen deposited on the alloy. The highest rate of nitrogen deposition was found at a treatment period of 20 hours. The results of immersing the samples for a month in a simulated body fluid showed the growth of a hydroxyapatite (HA) layer on the samples, where the growth of the hydroxide apatite layer was good on the samples within the simulated body fluid environment. The results of this examination indicated the compatibility of the alloy with the living organism's body.
