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 great wear resistance, corrosion resistance and oxidation resistance at high temperature (1000 ~ 1100 ℃). Coming from a cermet.

Especially chromium carbide has many outstanding properties, such as strong chemical stability, high solidity at space temperature and also thermal firmness, great resistance to acid and also alkali corrosion, great wear resistance, high melting factor, and excellent wettability with metals such as and also. In the metal carbide, the oxidation resistance of zui is high, and the oxidation temperature level is as high as. When chromium is utilized as an inhibitor, the grain development of cemented carbide can be efficiently managed. Moreover, chromium carbide is not only an additive of explosive bonding product with excellent wear resistance as well as a top quality cermet raw material. It can additionally be utilized as splashing powder. For instance, spraying powder has excellent deterioration, oxidation, and use resistance at heats. Due to its outstanding attributes, chromium carbide has been commonly used in the metallurgical market, electronic sector, high-temperature resistant coating, aerospace, as well as various other fields.

Chromium carbide has high hardness, high melting point, high flexible modulus, chemical corrosion resistance, and use resistance and has ended up being one of the commonly used steel carbides. In cutting devices, chromium carbide powder generally plays an essential duty as a surface coating. In Fe-Cr-C alloy, chromium carbide is a crucial rainfall phase, providing the product exceptional wear resistance. Chromium is an essential wear-resistant stage, while firmness, as a substantial mechanical criterion in the design of wear-resistant materials, has yet to get a fairly precise result.

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

Producing chromium carbide by a mix of aluminothermic reduction and also vacuum furnacing at temperature levels of 1500°& deg; C and above. A blend of chromium steel, chromium oxide and also carbon is prepared and then filled into a vacuum heating system. The stress in the heating system is lowered and the temperature boosted to 1500°& deg; C. The carbon responds with the chromium oxide to develop chromium steel as well as carbon monoxide gas, which is attracted off right into the vacuum cleaner pumps. The chromium metal then integrates with the remaining carbon to create the chromium carbide
