High-hardness and high-temperature resistance titanium carbide ceramic and preparation method thereof
The invention discloses a high-hardness and high-temperature resistance titanium carbide ceramic and a preparation method thereof. The ceramic is prepared from, by weight, 40-60 parts of titanium carbide, 10-25 parts of alumina, 2-7 parts of kaolin powder, 0.8-2 parts of zirconia, 1.5-4 parts of boron oxide, 2-6 parts of silica, 1.8-3.5 parts of antimony oxide, 0.6-3 parts of carbon fibers, 0.05-0.3 parts of a surfactant, 0.5-3 parts of polyethylene, 25-30 parts of anhydrous ethanol, 2-5 parts of glycerin and 65-75 parts of deionized water. The hardness (HV) of titanium carbide reaches 2400 or above, the compressive strength (MPa) reaches 4500 or above, and the bending strength (MPa) reaches 540 or above, and the preparation method has the advantages of simple process, convenient sources of raw materials, obvious improvement of the hardness and the wear resistance of the titanium carbide ceramic, and enlargement of the application range of the titanium carbide ceramic.
