Сeramic material based on titanium nitride produced by combustion synthesis
The combustion of the mixtures of micron powders of titanium and titanium oxide without additives and with the addition of micron aluminum powder in an amount of 10 wt. % in air were investigated. The samples of sintered ceramics on the based of SHS-powders, pre-heat-treated in nitrogen, were gotten by HIP (hot isostatic pressing) method. The best strength properties were obtained for ceramic samples with the addition of aluminum, which composition was represented by the phases of titanium nitride and corundum — the result of it was the indicators of microhardness ~17 MPa.
