What is the chemical stability of niobium carbide

What is NbC powder?

Niobium carbide is an eco-friendly cubic crystal with a metal radiance belonging to a sodium chloride-type cubic crystal system. Its melting point is high, its firmness is high (microhardness is 235GPa, which is more difficult than corundum), and also its chemical security is excellent (it is stable at one 000 ~ 1 100 ℃ and also quickly oxidizes to niobium pentoxide over one 100 ℃). Insoluble compounds are hot and cold hydrochloric acid, sulfuric acid, and also nitric acid, as well as they are only soluble in the warm mixed service of hydrofluoric acid as well as nitric acid. Niobium carbide is simple to melt in titanium carbide, zirconium carbide, tungsten carbide, as well as various other substances, resulting in an isomorphic solid service, so it can be used to manufacture cermet, heat-resistant alloy, and cemented carbide. The sealed carbide with niobium carbide has actually fine-tuned grain as well as enhanced all-around efficiency. The cutting tools made from it additionally have excellent thermal firmness, thermal shock resistance, and thermal oxidation resistance.

? As one of the raw products of composite ceramic products, composite ceramic products constructed from composite ceramic products are typically utilized in wear-resistant components, reducing devices, electrodes, and also other fields as a result of their high solidity, high melting factor, exceptional chemical security, as well as electrical conductivity.

Sealed carbide can not only be utilized as an inhibitor of cemented carbide grain development but additionally develop the 3rd spread stage other than WC and also Co together with other carbides, which can substantially improve the thermal solidity, thermal shock resistance, hot pressing resistance as well as oxidation resistance of cemented carbide. Niobium carbide can be used to prepare concrete carbide tool materials with superb cutting performance due to its benefits of increasing the hardness as well as boosting the fracture strength of the alloy.

The hard niobium carbide difficult phase of the surfacing-covered electrode gets in the structure of the appearing layer, which provides the welding layer a good wear-resistant skeletal system and also considerably improves the wear resistance. The wear resistance of this protected electrode surfacing wear-resistant alloy is 1.2 ~ 1.8 times more than that of quenched No. 45 steel (HRC50) as well as 2.4 ~ 3.6 times greater than Fe-Cr-C-B wear-resistant alloy. At the exact same time, the hard-facing layer can be bonded on the surface of the work surface without preheating, and the small cracks created externally can launch the anxiety of the hard-facing layer. They will not spread out into the base material. D. Adding a small amount of niobium carbide to the steel enhancing phase during steelmaking can accomplish the effects of rainfall strengthening as well as fine grain conditioning, hence enhancing the detailed mechanical buildings of steel.

Aerospace components are used as preparation products for numerous aerospace tools components, such as wind turbine blades, gas rudders, blades, engine nozzle linings, and also architectural participants of atomic power plants.
