The main characteristics of ultrafine nano titanium carbide, titanium carbide powder through a special process method, high purity, small particle size distribution, high specific surface area, high surface activity, high temperature resistance, oxidation resistance, is a kind of very good refractory wear-resistant material, widely used in hard alloy, wear-resistant superhard materials;Titanium carbide is about 3200 ℃, melting point is the important element of the hard alloy, high hardness, corrosion resistance, good thermal stability etc., used in making wear-resisting material, cutting tool, mold, metal smelting crucible, and many other areas;Because the particle size is small, it has high surface activity, good electrical conductivity and excellent chemical inertness to iron and steel metals.Adding 10,000th of nanometer titanium carbide can reduce the sintering temperature of titanium carbide ceramics by about 200 degrees, refine ceramic grain, and improve the sintering performance of ceramics.Nanometer titanium carbide can be used as ceramic material reinforcing phase to effectively improve the mechanical and electrical properties of metal and ceramic matrix materials.
Application field
1 nano titanium carbide used in the aerospace parts: considering the refractory nano carbide TiC, ZrC has above 3000 ℃, melting point has good high temperature strength, thermal expansion coefficient and good compatibility with tungsten, close, and is better than the density of tungsten is much lower.The strength of nanometer TiCp/w and ZrCp/w composite increases with temperature.Nano TiCp/w and ZrCp/w at 1000 ℃ and 800 ℃ respectively has the highest strength, compared with their room temperature strength increase significantly.Then the temperature goes up and the intensity goes down.This peculiar composite materials with the temperature increase is due to the high temperature strength W matrix by brittle into plastic, makes the nano TiC and ZrC particles in the heat of plastic W matrix to strengthen increasingly significant, composite material has excellent high temperature strength, and TiC nanoparticles than W matrix nanometer ZrC particles have better heat enhancement effect;
2 nanometer titanium carbide foam ceramics: as a filter, foam ceramics can effectively remove the inclusions in various fluids. The filtration mechanism is agitation and adsorption.Filter material of chemical stability, especially in the filter used in the metallurgical industry requires high melting point, so this kind of material in the majority with oxide, and in order to adapt to the metal melt filter, main pursuit of improving the performance of thermal shock.Compared with oxide foam ceramics, nanometer titanium carbide foam ceramics have higher strength, hardness, thermal conductivity, electrical conductivity, heat resistance and corrosion resistance.
3. It is widely used in manufacturing wear-resistant materials, cutting tools, molds, smelting metal crucible and other fields.Titanium carbide abrasive is an ideal material to replace traditional grinding materials such as alumina, silicon carbide, boron carbide and chromium oxide.The grinding capacity of nanometer titanium carbide is comparable to that of synthetic diamond, which greatly reduces the cost. It has been widely used in the United States, Japan, Russia and other countries.The abrasive, grinding wheel and grinding paste made of nanometer titanium carbide materials can greatly improve the grinding efficiency, grinding precision and surface finish.
4. Powder metallurgy field: nanometer titanium carbide powder is used as raw materials for manufacturing ceramic and hard alloy parts in powder metallurgy, such as drawing die and hard alloy die.Nanometer titanium carbide cemented carbide has the following characteristics: (1) high hardness, generally up to HRA90 or above;(2) good wear resistance and low wear rate;(3) good resistance to high temperature and oxidation;(4) good thermal conductivity and chemical stability.
