An inorganic compound, with the chemical formula Cr3C2 (molecular weight 180) Chrome carbide (Cr3C2), a gray powder, has metallic luster. High temperatures are good for corrosion resistance, wear resistance, and oxidation resistance of Chromium Carbide Powder (Cr3C2).
Chromium Carbide Preparation
Carbonization of metal chromium powder:
Carbon black is mixed with electrolytic chromemium in a mixture of 13.5% to 64 percent (more than the theoretical total carbon amount of 11.1.33% by weight) to make 325 mesh metallic chromium powder. This is then dried and combined with a ballmill as a raw material.
Use 1%-3% stearic to mold the material. Then press it with 1T/cm2 pressure or higher. Finally, heat the graphite pan orcrucible and place the pressed powder in a Taman or Induction Heating furnace. To make chromium carbonize, heat the hydrogen stream to between 1500 and 1700degC. The chromium carbonide is then produced by cooling.
Chromium Carbide Application
1. High melting point, chromium carbide has good wear resistance, corrosion resistance, and oxidation resistance at high temperatures. The nickel-chromium alloy is combined with cemented carbonide particles. It can also be used for high-temperature resistance, wear-resistant, and oxidation resistant coatings. These can be found in many aircraft engines as well as parts of petrochemical machinery. They can significantly increase the longevity of machinery.
2. The grain refiner of cemented carbide and other wear-resistant, corrosion-resistant components is often Chromium carbide. The high oxidation resistance of ceramics that are based on Cr3C2 is impressive.
3. The ceramics made from chromium carbonide are made with chromium carbide. For chromium-carbide ceramics, coarse-grained chromium-carbide is used to melt-blow materials. This allows for the formation of a layer on metals and ceramics that provides the desired properties, such as heat resistance, wear resistance, corrosion resistance, and heat resistance. To greatly increase the life of machinery, it is frequently used in engines for aircraft and components of petrochemical machinery.
4. To spray semiconductor film, you may also use chrome carbide.
