Why does chromium carbide have hardness

What is chromium carbide?

Chromium carbide ( Cr3C2) is grey powder with metal radiance; Orthorhombic system; The density is 6.68 g/cm3; The melting factor is 1890 ℃ and the boiling factor is 3800 ℃. It has good wear resistance, corrosion resistance and oxidation resistance at heat (1000 ~ 1100 ℃). Coming from a cermet.

Particularly chromium carbide has several superb homes, such as strong chemical stability, high hardness at area temperature and thermal firmness, great resistance to acid and alkali rust, good wear resistance, high melting point, and excellent wettability with metals such as and. In the steel carbide, the oxidation resistance of zui is high, and the oxidation temperature is as high as. When chromium is used as an inhibitor, the grain growth of cemented carbide can be efficiently controlled. In addition, chromium carbide is not only an additive of explosive bonding material with great wear resistance and also a top notch cermet resources. It can also be used as spraying powder. For instance, spraying powder has good corrosion, oxidation, and also wear resistance at high temperatures. Due to its superb qualities, chromium carbide has actually been extensively made use of in the metallurgical industry, electronic market, high-temperature immune coating, aerospace, and also various other areas.

Chromium carbide has high solidity, high melting point, high elastic modulus, chemical deterioration resistance, and also put on resistance and has actually turned into one of the commonly made use of steel carbides. In cutting devices, chromium carbide powder generally plays an important function as a surface layer. In Fe-Cr-C alloy, chromium carbide is an essential precipitation phase, offering the material exceptional wear resistance. Chromium is an important wear-resistant phase, while solidity, as a considerable mechanical specification in the design of wear-resistant materials, has yet to get a fairly precise outcome.

Chromium carbide (CnC) has a low firmness of 1710 and a thickness of 6.68 g. m), a thermal growth coefficient of 10.3 x 10 ~ K (20-100) and also a thermal conductivity of 19.1 W.m-+. K-1. Its primary features are that the carbide has a high space temperature, thermal solidity, as well as great wettability with metals such as CoNi. It is made use of in steel mold substances.

Making chromium carbide by a mix of aluminothermic reduction as well as vacuum furnacing at temperature levels of 1500°& deg; C as well as above. A blend of chromium metal, chromium oxide as well as carbon is prepared and also then loaded into a vacuum cleaner heating system. The pressure in the heating system is lowered as well as the temperature increased to 1500°& deg; C. The carbon responds with the chromium oxide to develop chromium metal as well as carbon monoxide gas, which is drawn off right into the air pump. The chromium steel then combines with the remaining carbon to create the chromium carbide
