Nitriding was carried out at 773 K to 1073 K for 3.6 ks to 32.4 ks. Alumina powders were used as the media that flowed in the barrel tank. A new surface hardening process was developed for forming hard layers on a pure titanium surface. A uniform hard layer could be formed on pure titanium surfaces using barrel nitriding. With barrel nitriding, the treatment time did not have an effect on the surface hardness, but had a strong effect on the depth of the hard layer. Moreover, nitrogen was able to diffuse into titanium surface, and TiN and Ti2N could be formed on the surface using this process.
