Why does chromium carbide have hardness?

Chrromium carbide is a gray powder with metallicluster. It is very resistant to corrosion, wear and oxidation. A cermet.

Chromium carbide is a strong, chemically stable, hardness at ambient temperature, thermal hardness, excellent resistance to acid, alkali and corrosion, wear resistance and good wettability when paired with metals such. Metal carbide has a high oxidation resistance and a high oxidation temp. Cemented carbide grain growth can be easily controlled by using chromium as an inhibiter. Chromium carbide has many other uses. It is an explosive bonding compound with high wear resistance. This can be used to spray powder. Spraying powder, for example, is highly resistant to corrosion, oxidation, wear, and high temperatures. Due to its outstanding characteristics, chromium carbonide is widely used in the metalurgical and electronic industries as well as aerospace and other areas.

One of the most popular metal carbides is chrome carbide. This has high hardness. high melting point. high elastic modulus. Chemical corrosion resistance. As a top coating, chromium carbide powder is used in cutting tools. Chromium carbide, which is an important precipitation phase for Fe-CrC alloy, gives it excellent wear resistance. The critical phase of wear resistance is Chromium, but hardness has still to be determined as an important mechanical parameter for the development and design wear-resistant materials.

CnC has a hardness of 17.10 and a density 6.68g. The thermal expansion coefficient is 10.3x 10K (20–100) and the thermal conductivity is 19.1W.m.-+.K-1. Carbide has the following main features: high room temperatures, good thermal hardness and good wettability in combination with metals, such as CoNi. It’s used in the manufacture of metal mold compounds.

The combination of aluminothermic and vacuum furnacing is required to make chromium carbide at temperatures up to 1500degC. After preparing the mixture of chromium metallic, chromium dioxide and carbon, it is loaded into a furnace. Temperature is increased to 1500°C by reducing the furnace’s pressure. After the carbon reacts to the chromium dioxide, it forms carbon monoxide and chromium metal. These are then drawn out into the vacuum pumps. This is then combined with remaining carbon to create the chromium carbid.

Many factors affect the Chromium-carbide market price. The market price of Chromium carbide is changing rapidly at the moment. You can contact us anytime if you require it.
