Boronizing of Ti-6Al-4V Eli by powder pack method for biomedical application

The boronization of Ti-6A1-4V Eli alloy was prepared by powder pack method. As a result of the boronizing process, the boride coating was presented as titanium boride (TiB) with a coating thickness about 2-9 /spl mu/m. Furthermore, the microhardness of the boron coating was about 500-800 HK. The microstructure of the coating was also observed by the optical microscope.
