The metallurgical structure and wear resistance of TiN film formed on 1%C-5%Cr roll steel specimens by Ti vapor deposition with N ions implantation were studied. The main results obtained are as follows : 1) The color of film varies depending on the evaporation rate of Ti and the electric current density of N ions. 2) The X-ray photoelectron spectroscopic (XPS) investigation detected TiN in the golden film and metallic Ti and TiO_2 in the silver film. 3) Measurements using a scanning electron microscope (SEM) with energy dispersive X-ray indicated that the concentration of Ti and Fe varies over the distance of a few hundred nm in the boundary zone between the base metal and the coated film. 4) The adhesion of golden film is better than that of silver one. 5) The two-cylinder-type wear resistance test results showed that the golden TiN film significantly improves wear resistance of 1%C-5%Cr roll steel.
