| Abstract: | The wear mechanism and curves of nano TiN modified TiC based cermet cutters, conventional Ti(C,N) based cermet cutters and the compared cemented carbide cutters have been investigated when used for cutting normalized 45 # steel. Results have shown that the effect of nano TiN modification on the TiC based cermet cutting tools was obvious. Cermet cutters showed better wear resistance than the compared cutters owing to their excellent comprehensive properties. The main failure mode were wear or tipping. |
