Titanium has a high specific strength and corrosion resistance. Surface treatment or coating is often required to improve surface hardness, however, because of titanium's low durability. In this study, a CO<sub>2</sub> laser beam was irradiated in nitrogen to form a hard nitride coating on a pure titanium plate. The hard layer formed by the reaction between titanium and nitrogen consisted of TiN and Ti<sub>2</sub>N. The surface hardness produced by the treatment exceeded Hv 7.5GPa.
