Preparation method of hafnium oxide surface modified titanium carbide powder
The invention discloses a preparation method of hafnium oxide surface modified titanium carbide powder, and relates to a modification method of titanium carbide powder. The technical problems that an existing preparation technology of the high-temperature-resistant powder coating is tedious and high in cost are solved. The method comprises the following steps: adding TiC powder into a hafnium salt solution, and dropwise adding concentrated ammonia water while stirring to obtain mixed slurry; and the mixed slurry is dried and then sintered in a vacuum furnace, and the hafnium oxide surface modified titanium carbide powder is obtained. The surface of the TiC powder is coated with the rare earth oxide, the high-temperature stability of the TiC powder is improved, the TiC powder oxidation phenomenon at the high temperature is inhibited, the problem that the TiC powder is prone to oxidation at the high temperature is effectively solved, and the hafnium oxide surface modified titanium carbide powder can be applied to the fields of metal ceramics, wear-resistant materials and high-temperature-resistant radiation materials.
