Micro Vickers hardness (load 50g) is 2700kg/rnrn2, thermal expansion coefficient is 10.3×10-6/K, insoluble in water, acid and alkali resistant, is a high melting point inorganic material, good wear resistance, in high temperature environment (1000-1100 degrees) Corrosion and oxidation resistance.

The production process of chromium carbide

Metal chromium powder carbonization method: carbon black and electrolytic chromium are crushed into 325 mesh metal chromium powder according to the ratio of 13.5% to 64% (mass) (exceeding the theoretical combined carbon content of 11.33%). After dry mixing with ball mill as raw material. Add 1% to 3% stearic acid as a molding lubricant. 1T/cChemicalbookm2 or more pressure compression molding. Put the pressed powder into a graphite plate or crucible, heat it to 1500-1700°C (the dew point of hydrogen is about -35°C) with a Taman furnace or an induction heating furnace in a hydrogen stream, and then keep it for 1 h to make the chromium A carbonization reaction occurs to form chromium carbide, which is cooled to obtain chromium carbide.

How is chromium carbide Cr3C2 powder produced?

Chromium carbide is produced by a combination of aluminothermic reduction and vacuum furnaces at temperatures of 1500°C and above. A mixture of chromium metal, chromium oxide and carbon is prepared and charged into a vacuum furnace. The pressure in the furnace decreased and the temperature rose to 1500°C. The carbon reacts with the chromium oxide to form chromium metal and carbon monoxide gas, which is pumped into a vacuum pump. The chromium metal then combines with the remaining carbon to form chromium carbide.

 The precise balance between chromium oxide, chromium metal and carbon determines the grade of chromium carbide produced. This is strictly controlled to ensure product quality suitable for demanding markets such as aerospace.

Chromium carbide Cr3C2 powder application

Chromium carbide Cr3C2 powder is a high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environment. Made of nichrome carbide particles, plasma sprayed for high temperature and wear resistance.

1. Anti-oxidation, anti-oxidation and acid-resistant coatings are widely used in aero-engines and petrochemical machinery and equipment, which can greatly improve the service life of machinery. It is also commonly used as a grain refiner for cemented carbide and cemented carbide. Other wear-resistant and corrosion-resistant parts. Cr3C2-based cermets have excellent oxidation resistance at high temperatures.

2. For chromium carbide ceramics. Coarse chromium carbide is used as a melt-blown material to form a melt-blown layer on the surface of metals and ceramics, thereby endowing ceramics with wear resistance, heat resistance, corrosion resistance and other properties. It is widely used in aircraft engines and petrochemical machinery, greatly extending the service life of the machinery. Also used for spraying semiconductor films.

3. As a thermal spray material, chromium carbide Cr3C2 powder is used to protect the underlying metal surface.

4. Additives for the manufacture of wear-resistant and corrosion-resistant materials.

5. As a coating for seals, bearings and valve seals.

6. As a microcrystalline phase in cemented carbide (such as vanadium carbide), chromium carbide Cr3C2 powder is used to inhibit the growth of submicron grains during pressing and sintering.
