The main characteristics of nano-titanium carbide, ultra-fine titanium carbide powder prepared through a special process method, high purity, small particle size distribution range, high specific surface area, high surface activity, high temperature, anti-oxidation, is a good refractory-resistant grinding material, is widely applied to the carbide, wear superhard materials above; titanium carbide the melting point of about 32 ℃, carbide components, with high hardness, corrosion resistance, good thermal stability, used in manufacturing wear-resistant materials, cutting tools, molds, melting metal crucibles and other areas; because the smaller particle size and therefore have a high surface activity, with good electrical conductivity, chemical inertness, and excellent performance as well as iron and steel metals; add ten thousandth of nano-titanium carbide can reduce titanium carbide ceramic sintering temperature of 200 degrees, and can be refined ceramic grain and improve the ceramic sintering process; nano-titanium carbide as a ceramic material reinforced to improve the mechanical properties of metal, ceramic matrix material and conductive properties.
Applications
1 nm titanium carbide used in aerospace components: taking into account the refractory nano-carbides TiC of ZrC has a melting point above 3000 ℃, with good high temperature strength, and good compatibility with tungsten, similar coefficient of thermal expansion, and has more than tungsten at a much lower density. Nano of TiCp / w and ZrCp / w composite strength with increasing temperature a gradual increase. Nano of TiCp / w and ZrCp / w at 1000 ℃ and 800 ℃ respectively, the highest strength was increased significantly compared with the intensity of the respective room temperature.Then the temperature continues to rise, the intensity decreased. Composites of this exotic high temperature strength, W the base body with the temperature to improve brittleness conversion for the plastic, making the nano-TiC and ZrC particles at a high temperature plastic W-based body’s enhanced role even more significant with, resulting in excellent high temperature strength of composite materials nano-TiC particles NONSTOICHIOMETRIC NANO ZrC particles W substrate have better high-temperature enhancement;
2 nm titanium carbide ceramic foam: ceramic foam as a filter in fluid inclusions can be effectively removed the filtering mechanism is stirred and adsorption. The filter requires the material’s chemical stability, especially in the metallurgical industry is using the filter requirements of high melting point, and therefore the majority of such material to the oxide, and to adapt to the filtration of the metal melt, mainly the pursuit of the improvement of the thermal shock resistance. Nano titanium carbide ceramic foam has a higher strength, hardness, thermal conductivity, electrical conductivity, and heat and corrosion resistance than the oxide ceramic foam;
Widely used in the manufacture of wear-resistant materials in many fields of cutting tools, molds, melting metal crucibles and other transparent titanium carbide ceramics and optical materials; titanium carbide abrasive of the abrasives and abrasive industry is an alternative to aluminum oxide, silicon carbide, boron carbide, an ideal material of chromium oxide and other traditional abrasive materials; nano-titanium carbide grinding comparable with the synthetic diamond, greatly reduces the cost in the United States, Japan, Russia and other countries has been widely used. Nano titanium carbide materials, abrasives, grinding wheels and grinding ointment products can greatly improve the grinding efficiency, and improve the grinding accuracy and surface finish.
4 field of powder metallurgy: Nano-titanium carbide powder for powder metallurgy production of ceramics, carbide parts of the raw materials, such as wire drawing dies, carbide dies and so on. Nano titanium carbide based cemented carbide has the following characteristics: (1) high hardness, generally up to HRA90 above; (2) wear resistance, low wear rate; (3) high temperature and antioxidant capacity; (4) good thermal conductivity, good chemical stability.
