Abstract: 

The paper analyzes the features of the MAX phases formation in the Ti-Al-C system; in particular, the possibility of thin layers of the amorphous phase (Ti-Al) forming on the surface of the TiC grains is discussed. Such layers cause increased crack resistance of ceramic materials based on MAX phases such as Ti2AlC, Ti3AlC2, TiAlC2, which are therefore durable and suitable for use as the basis for the manufacture of implants in medicine and biology.

Keywords: 
multi-component ceramics, MAX-phases, liquid-phase sintering, crack resistance.
