Overview of Chromium Carbide Cr3C2 Powder

Chromium carbide powder is a very hard refractory ceramic material. It is a fine gray powder and is rarely the natural mineral Tongbaishi. Chrome carbide has strong corrosion resistance and high-temperature oxidation properties, and its thermal properties are similar to steel. It is an excellent material for many commercial industries. Several chromium carbide compounds can be formed, each with slightly different mechanical properties and applications. Cr carbide is used as a thermal spray material for protecting the underlying metal surface and as an additive to corrosion-resistant and wear-resistant materials. Chromium carbide applications are particularly effective where sliding abrasion is present.

Production Method of Chromium Carbide Cr3C2 Powder

Producing chromium carbide by combining aluminothermic reduction and vacuum furnacing at 1500°C and above temperatures. A blend of chromium metal, chromium oxide, and carbon is prepared and loaded into a vacuum furnace. The pressure in the furnace is reduced, and the temperature increased to 1500°C. The carbon reacts with the chromium oxide to form chromium metal and carbon monoxide gas, which is drawn into the vacuum pumps. The chromium metal then combines with the remaining carbon to form the chromium carbide.

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

Chromium Carbide Properties

Chromium carbide, containing 13.34% carbon, is a gray powder orthorhombic crystal structure, insoluble in water, resistant to acid and alkali. Chromium Carbide density is 6.65-6.68 g/cm3, Chromium Carbide melting point is 1890 degrees, and boiling point is 3800 degrees. It is a high melting point inorganic material with good wear, corrosion, and oxidation resistance in a high-temperature environment (1000-1100 degrees). It is used as a thermal spray material for metal surface protection and is often used as a hard alloy. Grain refiners and other wear and corrosion-resistant components. The Chromium carbide-based cermet has excellent oxidation resistance at high temperatures, and the surface is only slightly darkened after 5 hours of heat exposure at 982 °C. Under the same conditions, 18-8 stainless steel has been significantly damaged, and WC-6Co alloy is completely oxidized.

Application of Chromium Carbide Cr3C2 Powder 

Chromium carbide Cr3C2 powder is a high melting point material with good wear, corrosion, and oxidation resistance in high-temperature environments. It is made of hard alloy particles made of nickel-chromium alloy and adopts a plasma spraying method, which can be used for high-temperature and wear resistance.

1. Oxidation and acid resistance coatings are widely used in aircraft engines, petrochemical machinery, and equipment, which can greatly increase the service life of machinery. It is also commonly used as a grain refiner for cemented carbide and other wear-resistant and corrosion-resistant parts. Cermets based on Cr3C2 have excellent oxidation resistance at high temperatures.

2. Used for chromium carbide ceramics. Coarse chromium carbide is used as a melt-blown material to form a melt-sprayed layer on the surface of metals and ceramics, imparting wear, heat, corrosion, and other properties to the latter. It is widely used in aircraft engines and petrochemical machinery to greatly increase the life of machinery. It is also used for spraying semiconductor films.

3. As a thermal spray material used to protect the metal surface below

4. Additives used to manufacture wear-resistant and corrosion-resistant materials

5. Chromium carbide coating: As a coating for seals, bearings, and valve seals. Chromium carbide overlay is a cost-effective, wear-resistant coating that significantly improves the life cycle of equipment compared with ordinary carbon steel.

6. The microcrystalline phase in cemented carbides (such as vanadium carbide) is used to inhibit the growth of sub-micron grains during pressing and sintering.
