Superhard Titanium Carbide Nanopowder As Ceramic Reinforcing Materials
Spec: 40-60nm, 99%,we could also do micron size titanium carbide powder.
Characteristic of titanium carbide nanopowder:
1. Nano-titanium carbide, small particle
size, distribution, large surface area, high surface activity, high
temperature, anti-oxidation, high hardness, is a good refractory wear-resistant
material, is widely used to carbide, superhard wear-resistant material above;
2. The nano titanium carbide has good
electrical conductivity, it can be used as the molten salt electrolysis
electrode material and conductive electrical contacts;
3. Add one ten thousandth of nanometer
titanium carbide can be reduced by titanium carbide ceramic sintering
temperature of 200 degrees, and can refine the grain, improve the sintering
properties;
4. Nano titanium carbide reinforcing phases
can be used as a ceramic material, a metal effective to improve the mechanical
properties of ceramic matrix material and conductive properties.
Application of titanium carbide nanopowder:
1 nanometer titanium carbide used in
aerospace components: Considering the refractory carbide nano TiC, ZrC having a
melting point above3000 ℃,
with excellent high temperature strength, and good compatibility with tungsten,
thermal expansion coefficients are similar, and has more than Tungsten much
lower density. The composite peculiar temperature strength due W substrate
temperature increased from brittleness into the plastic, so that nano TiC and
ZrC particles at high temperature to enhance the role of the plastic W matrix
even more significantly, resulting in composites with excellent high
temperature strength, The nano-particles of TiC particles W NONSTOICHIOMETRIC
ZrC matrix have better high temperature enhancement;
2 nm titanium carbide ceramic foam: foam
ceramics as a filter for a variety of fluid inclusions can be effectively
removed, the filtration and adsorption mechanism is agitation. Filter material
requirements chemical stability, especially in the metallurgical industry is
using the filter requires a high melting point, so the majority of such
materials as oxides, but also to adapt to the molten metal filter, the main
pursuit to improve 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;
3 is widely used in manufacturing
wear-resistant materials, cutting tools, dies, metal melting crucibles and
other areas transparent titanium carbide ceramics is a good optical material;
titanium carbide abrasives and abrasive abrasive industry is an alternative to
aluminum oxide, silicon carbide, boron carbide, traditional ideal material for
chromium oxide abrasive material; nano-titanium carbide abrasive materials,
abrasive wheel and ointment products can greatly improve the grinding
efficiency and grinding accuracy and surface finish.
4 PM areas: nano titanium carbide powder
used in powder metallurgy production of ceramics, cemented carbide parts of raw
materials, such as drawing dies, carbide tooling. Nano-titanium carbide-based
alloy has the following characteristics: (1) high hardness, generally up HRA90
above; (2) good wear resistance, low wear rate; (3) good heat and oxidation
resistance; (4) good thermal conductivity, good chemical stability.
