TiC-Ni Functionally Gradient Material Produced by SHS

Densified TiC-Ni functionally gradient material was produced by hot pseudo isostatic pressing just after self-propagating high-temperature synthesis.Ni composition varies continuosly and gradiently along the thickness of the reacted sample, remarkbly different from stepwise type before SHS.TiC particle sizes get smaller with Ni content increasing.Hardness values(HRA)and relative density of the gradient material also change with Ni contents.
