“…As an important ceramic tool material, TiCN-based cermets possess not only high hardness, favourable wear resistance, excellent high-temperature oxidation resistance, good chemical and electrochemical stabilities of ceramics but also excellent plasticity similar to cemented carbide, and thus they have been widely utilised in many areas namely aerospace industry, engineering machinery, high-speed cutting, oil and mining industries, and so forth. [1][2][3][4][5][6][7][8][9][10] However, one significant disadvantage for TiCN-based cermets is that their strength and toughness are still not high enough to be used in some industries, especially in elevated-temperature environment restricting its application, when compared with the traditional WC-Co cemented carbide materials.…”

Short carbon fibre (C f ) reinforced TiCN-based cermets (C f /TiCN composites) were produced by powder metallurgy method with pressureless sintering technology. The phase evolution, microstructure and fracture morphology of C f /TiCN composites were investigated. The results showed that TiC, TiN, WC, Cr 3 C 2 and Mo phases disappeared gradually and diffused into core and rim phases by dissolution-reprecipitation process, finally formed new hard TiCN core phases and complex compound (Cr, W, Mo, Ti)(CN) rim phases, with the sintering temperature increasing. The added C f did not change the 'core-rim' microstructure but improved the mechanical properties of TiCN-based cermets. The C f /TiCN composite containing 3 wt-% C f achieved the best comprehensive mechanical properties, with fracture toughness and bending strength increasing by about 14.4% and 30.8%, respectively, when compared with the composite without C f . Toughening and strengthening mechanisms of C f /TiCN composite were concluded as crack deflection and branch, as well as the pull-out, fracture and bridging of carbon fibres.

“…However, it is not easy to apply the brittle ceramic die to ironing of stainless steel cups. A TiCN-based cermet becomes more attractive for cutting tools because the cermet has excellent wear resistance (Fu et al, 2008;Chen et al, 2008). Therefore, the TiCN-based cermet is expected to be effective for improving the formability in ironing of stainless steel drawn cups.…”

A TiCN-based cermet die was utilised to improve the formability in ironing of stainless steel drawn cups. By employing the cermet die, additional coating was not required because it was made of hard TiCN having low friction. As a comparison, TiCcoated WC-Co, non-coated WC-Co and tool steel dies were used. The effects of the viscosity of a lubricant and the ironing speed on the formability for the cermet die were examined. The cermet die exhibited the largest seizure resistance. The performance of the cermet die in repeated ironing was evaluated. For repeated ironing using the cermet die, the occurrence of seizure was prevented up to 100 strokes. It was found that the cermet die with low friction was effective in ironing stainless steel drawn cups.

“…The cermet is a new kind of composite material of cutting tool, and widely used in ultra-high speed cutting, high speed dry cutting and hard material cutting because of their excellent wear resistance, good high temperature hardness, perfect chemical stability, very low friction coefficient to metals, and superior thermal deformation resistance [1]. As a new kind of cermet, Ti(C, N)-based cermet was developed by adding nano TiN into TiC-based cemets.…”

A systematic cutting test was conducted turning normalized AISI1045 carbon steel with two kinds of Ti (C, N)-based cermet cutters, which were made with micron and nanometer TiC powders. And the cutting performance and abrasion mechanism was discussed in the article. The effect of tool orthogonal clearance on tool life was also researched in this paper. Results showed that: The tool life was affected seriously by tool orthogonal clearance angle, and the optimum tool orthogonal clearance angle of Ti (C, N)-based cermet cutter was 5°when cutting normalized AISI1045 steel. The cutting Performance of Ti (C, N)-based cermet cutters which were made with nanoTiC powders was better than the ones which were made with micron TiC powders obviously. And the primary wear behaviors were wear.
