Introduction to Chromium Carbide Cr3C2 Powder

Chromium carbide is an inorganic compound with a molecular formula of Cr3C2 and a molecular weight of 180.01. Gray powder, diamond system, A=2.821, B=5.52, C=11.46. Melting point 1890 ℃, boiling point 3800 ℃. The micro-Vickers hardness (load 50g) is 2700kg/rnrn2, and the thermal expansion coefficient is 10.3×10-6/K. It has good wear resistance, corrosion resistance and oxidation resistance in high temperature environment (1000~1100 ℃). It belongs to a kind of cermet. Due to its special high temperature performance, it is widely used as a thermal spray material for metal surface protection processes and as an additive in the cemented carbide industry.

Physical and chemical properties of chromium carbide Cr3C2 powder

Chromium carbide has many excellent properties such as strong chemical stability, high temperature hardness, hot hardness, acid and alkali corrosion resistance, good wear resistance, and high melting point. When chromium carbide is used as an inhibitor, the grain growth of cemented carbide can be effectively controlled.

Moreover, chromium carbide is not only an additive for explosive bonding materials with good wear resistance, but also a high-quality cermet raw material. It can also be used as spray powder. For example, spray powder has good candle resistance and oxidation resistance at high temperatures. resistance, and wear resistance. It has been widely used in metallurgical industry, electronic industry, high temperature resistant coatings, aerospace and other fields.

In the field of cutting tools, chromium carbide often plays an important role as a surface coating. In Fe-Cr-c alloy, chromium carbide is an important precipitation phase, which makes the material have excellent wear resistance.

Application of Chromium Carbide Cr3C2 Powder

 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 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), it is used to inhibit the growth of submicron grains during pressing and sintering.
