Uniform particle size distribution, large batch production, can be used in a large number of cemented carbide, high surface activity,
It can be well dispersed in the alloy material, and dispersed and strengthened the alloy.
How is vanadium nitride VN powder produced?
The sample made of ammonium metavanadate powder and carbon powder is reduced in advance in a heating furnace, and then finally reduced. After the final reduction is completed, the sample is cooled in a furnace, and the sample obtained is vanadium nitride. During this process, the temperature of the heating furnace is 650-670°C, and the holding time is 2-4 hours. Under the conditions of this temperature and holding time, it can prevent the surface of the sample from melting and hinder the reduction reaction.
After pre-reduction, the main reduction product of the sample is V2O3, and the rest are carbides and a small amount of VN. During the final reduction process, the sample is kept warm at 1300~1500°C. During the heat preservation process, CO gas and CO gas are produced. It is taken away by the introduced nitrogen, and VN is obtained after the insulation is completed. During the reaction, the nitrogen flow rate is 210~270 ml/min, which not only satisfies the kinetic conditions of the reduction reaction, but also prevents excessive nitrogen reaction temperature. Reduce and waste nitrogen;
Overview of vanadium nitride VN powder
Vanadium nitride is formed during the nitriding process of steel and increases wear resistance. In the nitriding process, another phase V2N (also called vanadium nitride) can be formed together with VN. VN has a cubic rock salt structure. There is also a low-temperature form, which contains V4 clusters. When the vibration mode energy in the high-temperature NaCl-structure phase drops below zero, the low-temperature phase is caused by dynamic instability.
It is a strong coupling superconductor. It is said that nanocrystalline vanadium nitride has the potential to be used in supercapacitors. The properties of vanadium nitride are sensitively dependent on the stoichiometry of the material.
Application of vanadium nitride VN powder
Vanadium nitride has high wear resistance and can greatly improve vanadium steel after nitriding treatment.
The comprehensive mechanical properties of high-strength steel, such as strength, toughness, ductility and thermal fatigue resistance, give the steel good weldability. When the same strength is reached, adding vanadium nitride can save 20-40% of the vanadium addition, thereby reducing costs.
Vanadium-nitrogen alloy can be used for structural steel, tool steel, pipe steel, steel bar and cast iron. Vanadium-nitrogen alloy used in high-strength low-alloy steel
It can carry out effective vanadium and nitrogen microalloying at the same time, promote the precipitation of carbon, vanadium and nitrogen compounds in the steel, and play a more effective role in strengthening settlement and refinement.
Adding vanadium nitride to steel can improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability.
When the same strength is reached, adding vanadium nitride can save 30-40% of the vanadium addition, thereby reducing costs. Vanadium-nitrogen alloy can be used for structural steel, tool steel, pipe steel, steel bar and cast iron.
The vanadium-nitrogen alloy used in high-strength low-alloy steel can simultaneously perform effective vanadium and nitrogen microalloying, promote the precipitation of carbon, vanadium and nitrogen compounds in the steel, and more effectively play the role of settlement strengthening and graining. Refinement.
