Why does chromium carbide have hardness

What is chromium carbide?

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

Specifically chromium carbide has many superb buildings, such as solid chemical stability, high hardness at area temperature as well as thermal solidity, good resistance to acid as well as alkali corrosion, excellent wear resistance, high melting point, and also good wettability with metals such as and. In the metal carbide, the oxidation resistance of zui is high, and the oxidation temperature is as high as. When chromium is used as a prevention, the grain growth of concrete carbide can be effectively managed. Furthermore, chromium carbide is not just an additive of explosive bonding product with excellent wear resistance and also a premium cermet basic material. It can additionally be utilized as splashing powder. For example, spraying powder has great rust, oxidation, as well as use resistance at high temperatures. Because of its excellent features, chromium carbide has actually been widely made use of in the metallurgical sector, electronic industry, high-temperature resistant layer, aerospace, and various other areas.

Chromium carbide has high firmness, high melting point, high flexible modulus, chemical deterioration resistance, and wear resistance as well as has actually turned into one of the widely utilized metal carbides. In reducing devices, chromium carbide powder normally plays an essential function as a surface area finish. In Fe-Cr-C alloy, chromium carbide is a crucial rainfall phase, providing the material outstanding wear resistance. Chromium is a vital wear-resistant phase, while hardness, as a substantial mechanical specification in the style of wear-resistant materials, has yet to obtain a reasonably precise outcome.

Chromium carbide (CnC) has a reduced hardness of 1710 and also 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 major characteristics are that the carbide has a high space temperature, thermal firmness, and good wettability with metals such as CoNi. It is made use of in steel mold and mildew substances.

Producing chromium carbide by a combination of aluminothermic reduction and also vacuum cleaner furnacing at temperature levels of 1500°& deg; C and also above. A blend of chromium steel, chromium oxide and carbon is prepared and after that filled into a vacuum cleaner heater. The pressure in the heater is minimized as well as the temperature level boosted to 1500°& deg; C. The carbon reacts with the chromium oxide to create chromium steel and also carbon monoxide, which is drained into the vacuum pumps. The chromium steel after that integrates with the staying carbon to develop the chromium carbide
