Titanium carbide powder with hardness increased to HRC90
Titanium carbide powder has high sintering activity and can be sintered densely at 1300-1500℃, which is 200-300℃ lower than the sintering temperature of alumina ceramics, thus saving energy costs. Compared with other ceramic powders (such as silicon carbide), it has better toughness, with a fracture toughness of up to 6MPa·m¹/², making it suitable for manufacturing structural ceramic parts. The powder can be made into granular form through spray drying, which is convenient for forming and processing. The density of the compact can reach more than 65% of the theoretical density. In the field of wear-resistant valves, ceramic valves made from this powder can withstand the erosion of high-pressure fluids and have a service life 20 times that of steel valves. The particle morphology of this powder is controllable and can be made into spherical, quasi-spherical or irregular shapes to meet the requirements of different forming processes. Spherical powder has good fluidity and is suitable for laser 3D printing. The density of the printed parts can reach 99.8%, and its mechanical properties are comparable to those of traditional sintered parts. The bulk density of powder can be adjusted by particle size. Fine powder has a low bulk density and is suitable for pressing complex-shaped parts. Coarse powder has a high bulk density and is suitable for forming large-sized green bodies. In the field of personalized medical implants, 3D-printed titanium carbide parts are well compatible with human bones, and they are of high strength and light weight.
