Abstract:Abstract. Porous TiC-Ni based cermets were obtained by dispersion of carbides, oxides or borides particles in a nickel matrix thanks to the thermal explosion technique realized under a load of 20 MPa. The combustion of active mixtures (Ti-C-Ni-A n where A n = Al 2 O 3 , MgO, SiC, TiB 2 or WC) based on the titanium carbide reaction synthesis ( H f = −184 kJ/mol), generates porous complex cermets. After the thermal explosion, a short maintenance under load at 1373 K of the combustion product, allows at the same … Show more
