Ferrochromium nitride powder is an important alloy additive. It is made by reacting ferrochromium nitride with nitrogen. This powder has high hardness and high heat resistance and is generally used in the production of alloy steel and stainless steel.
Preparation method of ferrochromium nitride powder of Zhenxin Metallurgy.
• Vacuum heating nitriding method: crush low carbon ferrochrome to less than 3mm, take 1000kg and nitriding in vacuum heating furnace at 1150℃ and nitrogen pressure 0.0987MPa for 24h to obtain crude ferrochrome nitride, crush it to less than 0.3mm after cooling, nitriding again at 950℃, crush it to less than 0.3mm after cooling, put it into reactor, treat it with sulfuric acid, filter, wash with water, dry, and obtain ferrochrome nitride powder.
• Ammonia reduction method: react ammonia and chromium halide to prepare ferrochrome nitride powder.
• Plasma deposition method: using cathode arc plasma deposition technology, the ionization rate in the emitted particle flow is high, and the ions have high kinetic energy. When the chromium ions encounter nitrogen, chemical reactions occur to generate gaseous chromium nitride molecules, and then ferrochrome nitride powder is obtained.
New application areas of ferrochrome nitride powder.
- Coating materials. By applying ferrochrome nitride powder to metal surfaces, such as parts and tools, the surface hardness, corrosion resistance and wear resistance can be enhanced.
- 3D printing materials. Ferrochromium nitride powder can print complex parts. When using ferrochromium nitride powder for printing, it can effectively increase the service life of the parts.
- New energy. Ferrochromium nitride powder is also used in batteries because it is conductive. Adding ferrochromium nitride powder to battery research and development can improve battery performance and increase service life.
