Why does chromium carbide have hardness

What is chromium carbide?

Chromium carbide ( Cr3C2) is gray powder with metal appeal; Orthorhombic system; The density is 6.68 g/cm3; The melting point is 1890 ℃ and also the boiling factor is 3800 ℃. It has good wear resistance, deterioration resistance and also oxidation resistance at high temperature (1000 ~ 1100 ℃). Coming from a cermet.

Especially chromium carbide has numerous outstanding residential or commercial properties, such as strong chemical stability, high hardness at area temperature and also thermal hardness, good resistance to acid as well as alkali rust, excellent wear resistance, high melting factor, as well as good wettability with steels such as and also. In the steel carbide, the oxidation resistance of zui is high, and also the oxidation temperature is as high as. When chromium is utilized as an inhibitor, the grain development of concrete carbide can be efficiently regulated. Furthermore, chromium carbide is not only an additive of eruptive bonding material with good wear resistance as well as a high-quality cermet raw product. It can likewise be made use of as splashing powder. As an example, spraying powder has excellent deterioration, oxidation, as well as use resistance at heats. Due to its exceptional qualities, chromium carbide has actually been extensively utilized in the metallurgical sector, electronic sector, high-temperature immune finishing, aerospace, and also other areas.

Chromium carbide has high solidity, high melting point, high flexible modulus, chemical deterioration resistance, as well as use resistance and also has turned into one of the commonly used metal carbides. In cutting tools, chromium carbide powder normally plays an important function as a surface finishing. In Fe-Cr-C alloy, chromium carbide is a vital rainfall stage, offering the material exceptional wear resistance. Chromium is a crucial wear-resistant stage, while firmness, as a significant mechanical parameter in the layout of wear-resistant products, has yet to obtain a relatively precise outcome.

Chromium carbide (CnC) has a low hardness of 1710 and a thickness of 6.68 g. m), a thermal expansion coefficient of 10.3 x 10 ~ K (20-100) and also a thermal conductivity of 19.1 W.m-+. K-1. Its primary attributes are that the carbide has a high space temperature level, thermal firmness, as well as good wettability with metals such as CoNi. It is used in steel mold and mildew compounds.

Making chromium carbide by a mix of aluminothermic decrease as well as vacuum cleaner furnacing at temperature levels of 1500°& deg; C and also over. A mix of chromium metal, chromium oxide as well as carbon is ready and afterwards filled 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 metal as well as carbon monoxide gas, which is drained right into the air pump. The chromium steel then combines with the staying carbon to form the chromium carbide
