Material introduction of tantalum carbide

Tantalum carbide is a light brown metallic cubic crystalline 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, with a density of 14.3g/cm3. It is insoluble in water, hardly soluble in inorganic acid, soluble in mixed acid of hydrofluoric acid and nitric acid, and can be decomposed. Strong oxidation resistance, easily melted and decomposed by potassium pyrosulfate. The electrical conductivity is large, and the resistance is 30Ω at room temperature, showing superconducting properties. Used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy tools, tools, molds and wear-resistant and corrosion-resistant structural components additives to improve the toughness of the alloy. The sintered body of tantalum carbide is golden yellow and can be used as a watch decoration.

Material introduction of tantalum carbide

Metal matrix composite materials have received extensive attention from scientists in the field of materials of various countries due to their unique advantages of high specific strength, high specific modulus, wear resistance and high temperature resistance. The research on metal matrix composites mainly focuses on the overall uniform compounding, but because the wear only occurs on the surface of the parts, the overall compounding is not conducive to the recovery and reuse of materials and causes pollution to the environment. On the other hand, many studies have shown that wear-resistant materials need to have both high hardness and high toughness, while the overall composite only improves the hardness, but cannot improve the toughness, while the metal-ceramic composite material maintains the high hardness and high toughness of ceramics. Excellent performance such as wear resistance, and high toughness and high ductility of the metal matrix.

Carbide particles have the advantages of high strength, high hardness, and good wettability with the matrix. As a 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. And achieved very good practical application effects. The carbide particles reported mainly include tungsten carbide (WC), titanium carbide (TiC), niobium carbide (NbC) and vanadium carbide (VCp), etc. However, tantalum, an element of the same family as metal vanadium and niobium, has not been studied.

Tantalum carbide (TaC) ceramic particles have the advantages of high melting point (3880℃), high hardness (2100HV0.05), good chemical stability, and strong electrical and thermal conductivity. However, due to their cost and other issues, the reports seen are limited to nickel-based, 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 the in-situ reaction and directional solidification of tantalum carbide and its microstructure with chromium-based, chromium-based, and aluminum-based reinforcement. The results show that as the solidification rate increases, the solid phase structure changes, and the volume fraction of tantalum carbide also changes with the solidification rate. Change; Wang Wenli and others used laser cladding technology to prepare in-situ TaC particle-reinforced nickel-based composite coating on the surface of A3 steel. The results show that under appropriate process conditions, it generates TaC particle-reinforced nickel-based composite coating. Good, smooth surface, good metallurgical bonding between the coating and the substrate. However, there are few reports on the in-situ formation of TaC on the steel base. Therefore, the method of surface ceramic particles reinforced iron-based composite was used in this experiment. At the same time, TaC particles are selected as the second phase particle reinforcement phase. Analyze the microscopic morphology and reaction process of the iron-based surface composites reinforced with TaC particles in situ

Overview of Tantalum Carbide

Tantalum carbide powder is insoluble in water, almost insoluble in inorganic acid, soluble in a mixed acid of hydrofluoric acid and nitric acid, and can be decomposed. Very strong anti-oxidation, easy to be melted and decomposed by potassium pyrosulfate. The room temperature resistance is 30Ω, showing superconductivity. (TaC) can be used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy tools, tools, molds and wear-resistant and corrosion-resistant structural parts to improve the toughness of the alloy. The main body of tantalum carbide (TaC) is golden yellow and can be used as an ornament of a watch.

Application of Tantalum Carbide

Tantalum Carbide (TaC) is an extremely hard (Mohs hardness 9-10) refractory ceramic material that is commercially used for cutting tool tips. Diamond exceeds the hardness.

It is a heavy brown powder, usually processed by sintering, and is an important cermet material. Sometimes used as a microcrystalline additive for tungsten carbide alloys.

The difference between tantalum carbide is that it is a stoichiometric binary compound with a known highest melting point of 4150 K (3880°C) and a boiling point of 5500 oC.

The substoichiometric compound TaC0.89 has a relatively high melting point, close to 427 (4000°C).
