Abstract:

The need for cutting tool materials with improved toughness, elevated temperature strength and chemical inertness capable of operating at high cutting speed or dry cutting, is increasing. The use of various addition to a ceramic matrix provides great improvement in mechanical and other properties. UHTC materials due to extremely high melting points, higher than 3000C are widely investigated as potential candidates for high temperature application at machining conditions. Fast technique and the high pressure methods (HP-HT) allow to limit the sintering duration, the sintering temperature, so the sintering of materials with high melting point is possible. Because of the advantageous sintering conditions for these methods, there is possibility to consolidate the ceramic materials with solid lubricants characterized by low melting point or the temperature of decomposition. New trends for tool materials and own experimental results of high temperature sintering using SPS and HP-HT methods for various materials (oxides, nitrides and MAX phase composites) will be presented. The results of X-ray phase composition analysis, electron microscopy microstructure observations and selected physical, mechanical studies for these materials will be discussed.
