Why does chromium carbide have hardness

What is chromium carbide?

Chromium carbide ( Cr3C2) is grey powder with metal gloss; Orthorhombic system; The thickness is 6.68 g/cm3; The melting factor is 1890 ℃ and also the boiling factor is 3800 ℃. It has excellent wear resistance, deterioration resistance and oxidation resistance at high temperature level (1000 ~ 1100 ℃). Belonging to a cermet.

Especially chromium carbide has lots of outstanding buildings, such as strong chemical stability, high solidity at area temperature level and also thermal solidity, excellent resistance to acid as well as alkali corrosion, excellent wear resistance, high melting point, and also great wettability with steels such as and also. In the steel carbide, the oxidation resistance of zui is high, and the oxidation temperature level is as high as. When chromium is used as a prevention, the grain development of cemented carbide can be effectively regulated. Additionally, chromium carbide is not just an additive of explosive bonding product with good wear resistance and also a high-quality cermet raw material. It can also be made use of as spraying powder. As an example, splashing powder has good corrosion, oxidation, as well as use resistance at high temperature levels. As a result of its excellent attributes, chromium carbide has actually been extensively made use of in the metallurgical sector, electronic market, high-temperature resistant covering, aerospace, and also other fields.

Chromium carbide has high hardness, high melting factor, high flexible modulus, chemical rust resistance, and use resistance and also has become one of the widely utilized steel carbides. In cutting tools, chromium carbide powder generally plays a crucial role as a surface area coating. In Fe-Cr-C alloy, chromium carbide is a vital precipitation stage, giving the material excellent wear resistance. Chromium is an important wear-resistant stage, while solidity, as a significant mechanical criterion in the design of wear-resistant materials, has yet to obtain a fairly accurate result.

Chromium carbide (CnC) has a reduced solidity of 1710 and also a thickness of 6.68 g. m), a thermal expansion coefficient of 10.3 x 10 ~ K (20-100) as well as a thermal conductivity of 19.1 W.m-+. K-1. Its major features are that the carbide has a high room temperature level, thermal firmness, and good wettability with metals such as CoNi. It is utilized in metal mold substances.

Making chromium carbide by a mix of aluminothermic decrease and vacuum furnacing at temperatures of 1500°& deg; C and also over. A mix of chromium steel, chromium oxide and carbon is prepared and then loaded right into a vacuum cleaner furnace. The pressure in the furnace is minimized as well as the temperature level raised to 1500°& deg; C. The carbon responds with the chromium oxide to develop chromium steel as well as carbon monoxide gas, which is drained right into the air pump. The chromium steel then incorporates with the remaining carbon to develop the chromium carbide
