Why does chromium carbide have hardness

What is chromium carbide?

Chromium carbide ( Cr3C2) is gray powder with metallic luster; Orthorhombic system; The density is 6.68 g/cm3; The melting point is 1890 ℃ and also the boiling point is 3800 ℃. It has great wear resistance, deterioration resistance as well as oxidation resistance at high temperature (1000 ~ 1100 ℃). Belonging to a cermet.

Specifically chromium carbide has many exceptional homes, such as strong chemical stability, high firmness at area temperature level and thermal firmness, excellent resistance to acid as well as alkali deterioration, excellent wear resistance, high melting point, and good wettability with metals such as and. In the steel carbide, the oxidation resistance of zui is high, and the oxidation temperature level is as high as. When chromium is made use of as an inhibitor, the grain development of concrete carbide can be successfully regulated. Furthermore, chromium carbide is not only an additive of explosive bonding material with excellent wear resistance as well as a top quality cermet resources. It can additionally be used as splashing powder. For example, spraying powder has great deterioration, oxidation, as well as put on resistance at high temperature levels. Because of its outstanding attributes, chromium carbide has been commonly made use of in the metallurgical market, digital market, high-temperature immune covering, aerospace, and other fields.

Chromium carbide has high solidity, high melting factor, high flexible modulus, chemical deterioration resistance, as well as put on resistance as well as has turned into one of the extensively made use of steel carbides. In reducing tools, chromium carbide powder usually plays an essential role as a surface area finish. In Fe-Cr-C alloy, chromium carbide is a critical rainfall stage, offering the product outstanding wear resistance. Chromium is a vital wear-resistant phase, while firmness, as a significant mechanical parameter in the style of wear-resistant products, has yet to obtain a reasonably exact result.

Chromium carbide (CnC) has a reduced hardness of 1710 and also a thickness of 6.68 g. m), a thermal growth 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 space temperature level, thermal solidity, as well as good wettability with metals such as CoNi. It is used in steel mold and mildew compounds.

Producing chromium carbide by a combination of aluminothermic decrease and vacuum cleaner furnacing at temperature levels of 1500°& deg; C as well as above. A mix of chromium steel, chromium oxide as well as carbon is prepared and afterwards filled into a vacuum cleaner heating system. The pressure in the heating system is reduced and also the temperature level boosted to 1500°& deg; C. The carbon reacts with the chromium oxide to create chromium metal and carbon monoxide, which is attracted off into the vacuum cleaner pumps. The chromium metal then combines with the remaining carbon to develop the chromium carbide
