| Research Abstract |
In this work, the hardness and the frictional properties of Ti-B-C films have been improved by controlling the contents of boron and carbon. TiB_<2+α> films obtained with TiB_2+10wt%B target had the high hardness above 35GPa. The friction coefficients of Ti-B-C films with the carbon content above 40% were about 0.2. In the cutting Ti alloys, tip formation process had been improved and the surface roughness of the work piece became smooth by using the Ti-B-C coated tools.
