One-step synthesis and densification of Ti-Al-C-based cermets by ETEPC

Résumé

The Electro-Thermal Explosion under Pressure with Confinement (ETEPC) mode of SHS has been studied for producing possibly low-porosity Ti₂AlC and Ti₃AlC₂ from elemental powders in a very short processing time. The effect of maintaining the electric current after the ignition of exothermic reaction has also been studied. A better achievement of the desired reaction, with a total yield of MAX phases up to 73%, was obtained with maintaining the electric current for 4 s after ignition of the exothermic reaction in the Ti:Al:C = 2:1:1 composition. XRD studies revealed also composition gradients.
