Why does chromium carbide have hardness

What is chromium carbide?

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

Particularly chromium carbide has numerous excellent residential or commercial properties, such as solid chemical stability, high firmness at room temperature level and thermal hardness, good resistance to acid and also alkali rust, great wear resistance, high melting point, and also good wettability with metals such as and also. In the steel carbide, the oxidation resistance of zui is high, and also the oxidation temperature level is as high as. When chromium is made use of as a prevention, the grain development of cemented carbide can be effectively controlled. Moreover, chromium carbide is not just an additive of eruptive bonding material with great wear resistance and a premium cermet raw product. It can additionally be used as splashing powder. For example, splashing powder has great corrosion, oxidation, and also use resistance at heats. Because of its superb attributes, chromium carbide has been widely utilized in the metallurgical market, digital industry, high-temperature resistant finish, aerospace, as well as other areas.

Chromium carbide has high solidity, high melting point, high flexible modulus, chemical corrosion resistance, and also put on resistance as well as has actually become one of the widely utilized metal carbides. In reducing devices, chromium carbide powder typically plays a crucial role as a surface area coating. In Fe-Cr-C alloy, chromium carbide is a crucial precipitation stage, giving the product exceptional wear resistance. Chromium is a critical wear-resistant phase, while hardness, as a considerable mechanical criterion in the design of wear-resistant materials, has yet to obtain a fairly accurate 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 characteristics are that the carbide has a high space temperature, thermal firmness, and excellent wettability with steels such as CoNi. It is used in steel mold and mildew compounds.

Making chromium carbide by a mix of aluminothermic reduction and vacuum cleaner furnacing at temperatures of 1500°& deg; C as well as over. A blend of chromium metal, chromium oxide and carbon is ready as well as then packed right into a vacuum cleaner heater. The stress in the heating system is reduced and also the temperature increased to 1500°& deg; C. The carbon responds with the chromium oxide to create chromium steel and also carbon monoxide, which is drained right into the air pump. The chromium metal then incorporates with the continuing to be carbon to develop the chromium carbide
