The possibility for improving the thermal stability of polycrystalline materials based on diamond (PCD) is to reduce the content of cobalt. Diamond compacts without cobalt phases with Ti3₃iC₂ і Cr₂AlC prepared using the method of self-propagating high-temperature synthesis (SHS). The resulting compacts with 20 wt. % of the above phases were exposed to high pressure and temperature in order to further consolidate the structure by sintering. Sintering was performed at 8±0.2 GPa and 1950±50 °C. Phase composition and microstructural study of the original compacts and the composites made by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
