Synthesis of WC–Ni composite powders by thermochemical processing method based on co-precipitation

The synthesis of nano-sized, uniformly distributed WC-Ni powders was studied through co-precipitation of oxide powders followed by thermochemical reduction and carburization. Ni and W oxide complexes were first obtained from their salts’ solutions through chemical co-precipitation method by adjusting pH. The precipitated powders were then calcined to obtain a mixture of their oxides as WO3 and NiWO4 which were reduced and carburized …
