| Abstract: | Ti(C,N) based cermets have been widely used as a cutter material for their good comprehensive properties.The effect of nano TiN modification on the microstructure of TiC based cermets cutter was discussed in the paper.The wear mechanism and curves of nano TiN modified TiC based cermets cutters(cermet nm ) and the compared Ti(C,N) based cermets cutters(cermet μm ),YG8 cutters have also been investigated in cutting gray cast iron.Results showed that the effect of nano TiN modification on the TiC-based cermets cutters was obvious.cermet nm cutters showed higher tool lives and better wear resistance than the compared cermet μm and YG8 cutters.The main failure mode of cermet nm cutter was tipping. |
