What is Tantalum Carbide?
Tantalum carbide is a light brown metallic cubic crystal powder, belonging to the sodium chloride type cubic crystal system. Tantalum carbide is also used as a cemented carbide sintered grain growth inhibitor, which has a significant effect on inhibiting grain growth, and the density is 14.3g/cm3. Insoluble in water, insoluble in inorganic acid, soluble in mixed acid of hydrofluoric acid and nitric acid and decomposed. Strong antioxidant capacity, easily melted and decomposed by potassium pyrosulfate. High conductivity, resistance at room temperature is 30Ω, showing superconducting properties. Used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy cutting tools, tools, molds and wear-resistant and corrosion-resistant structural components additives to improve the toughness of alloys. The sintered body of tantalum carbide shows golden yellow and can be used as watch decoration.
The main features of Tantalum Carbide
Tantalum carbide (TaC) ceramic particles have the advantages of high melting point (3880°C), high hardness (2100HV0.05), good chemical stability, and strong electrical and thermal conductivity. Aluminum base and other substrates. Chao et al. used laser cladding technology to prepare a nickel-based reinforced tantalum carbide surface composite material. The results show that compared with pure nickel, the hardness of this material is significantly improved, and the wear rate is significantly lower than that of hardened steel; Yu et al. The relationship between in-situ reaction directional solidification of tantalum carbide enhanced by base, chromium base and aluminum base and its microstructure, the results show that with the increase of solidification rate, the solid phase structure changes, and the volume fraction of tantalum carbide also changes with the change of solidification rate. Wang Wenli et al. used laser cladding technology to prepare an in-situ TaC particle-enhanced nickel-based composite coating on the surface of A3 steel. Good, smooth surface, good metallurgical bond between coating and substrate. However, there are few reports on the in situ generation of TaC on steel substrates. Therefore, the method of surface ceramic particles reinforced iron matrix composite was adopted in this experiment. At the same time, TaC particles are selected as the reinforcement phase of the second phase particles. The microscopic morphology and reaction process of TaC particles in-situ reinforced iron-based surface composites were analyzed.

The applications of Tantalum Carbide
1. In cemented carbide, it is widely used as an additive, and its main function is to improve the high temperature strength of cemented carbide and inhibit the growth of tungsten carbide particles.
2. In cutting tools, as a hard coating to increase the chemical corrosion resistance and wear resistance of the base metal.
3. In the military, it can be used as chemicalbook coating for jet engine turbine blades and rocket nozzles, which can significantly improve its ablation resistance and prolong its service life.
4. Because of its good electrical conductivity. Therefore, it can be used for electrode materials, but also can be cut into complex shapes using wire EDM.
5. As the second phase particle reinforced metal matrix composite material, it has been widely used in aerospace, metallurgy, building materials, electric power, hydropower, mining and other fields.
