Why does chromium carbide have hardness

What is chromium carbide?

Chromium carbide ( Cr3C2) is gray powder with metallic gloss; Orthorhombic system; The thickness is 6.68 g/cm3; The melting point is 1890 ℃ and also the boiling factor is 3800 ℃. It has good wear resistance, rust resistance and also oxidation resistance at heat (1000 ~ 1100 ℃). Belonging to a cermet.

Especially chromium carbide has lots of outstanding properties, such as strong chemical security, high solidity at room temperature and also thermal hardness, great resistance to acid as well as alkali deterioration, great wear resistance, high melting point, and good wettability with steels such as and. In the metal carbide, the oxidation resistance of zui is high, as well as the oxidation temperature is as high as. When chromium is utilized as a prevention, the grain growth of concrete carbide can be successfully controlled. Furthermore, chromium carbide is not just an additive of eruptive bonding product with excellent wear resistance as well as a premium cermet raw product. It can additionally be used as spraying powder. For instance, spraying powder has excellent deterioration, oxidation, and also use resistance at high temperature levels. Because of its excellent features, chromium carbide has actually been widely utilized in the metallurgical sector, electronic industry, high-temperature resistant layer, aerospace, and various other fields.

Chromium carbide has high hardness, high melting factor, high elastic modulus, chemical rust resistance, and also use resistance as well as has actually ended up being one of the widely made use of metal carbides. In cutting tools, chromium carbide powder generally plays a crucial function as a surface area layer. In Fe-Cr-C alloy, chromium carbide is a critical precipitation phase, giving the product exceptional wear resistance. Chromium is a crucial wear-resistant phase, while firmness, as a substantial mechanical specification in the style of wear-resistant materials, has yet to get a relatively precise result.

Chromium carbide (CnC) has a reduced hardness of 1710 and also a density of 6.68 g. m), a thermal development coefficient of 10.3 x 10 ~ K (20-100) and also a thermal conductivity of 19.1 W.m-+. K-1. Its major qualities are that the carbide has a high room temperature level, thermal firmness, and excellent wettability with metals such as CoNi. It is made use of in steel mold compounds.

Producing chromium carbide by a mix of aluminothermic reduction and vacuum furnacing at temperatures of 1500°& deg; C and above. A mix of chromium metal, chromium oxide and carbon is ready and afterwards filled into a vacuum cleaner heater. The stress in the heater is lowered as well as the temperature level enhanced to 1500°& deg; C. The carbon responds with the chromium oxide to develop chromium steel and carbon monoxide gas, which is drawn off into the vacuum pumps. The chromium steel then incorporates with the continuing to be carbon to create the chromium carbide
