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 point is 1890 ℃ and also the boiling factor is 3800 ℃. It has excellent wear resistance, deterioration resistance as well as oxidation resistance at high temperature level (1000 ~ 1100 ℃). Coming from a cermet.

Specifically chromium carbide has several exceptional properties, such as strong chemical stability, high hardness at space temperature and thermal solidity, great resistance to acid and alkali rust, excellent wear resistance, high melting factor, as well as great wettability with steels such as and also. In the steel carbide, the oxidation resistance of zui is high, and the oxidation temperature is as high as. When chromium is utilized as an inhibitor, the grain growth of cemented carbide can be properly regulated. Additionally, chromium carbide is not only an additive of explosive bonding material with good wear resistance and also a high-grade cermet basic material. It can likewise be made use of as spraying powder. As an example, splashing powder has excellent deterioration, oxidation, and also wear resistance at heats. Due to its exceptional qualities, chromium carbide has actually been commonly utilized in the metallurgical market, digital market, high-temperature resistant coating, aerospace, as well as other areas.

Chromium carbide has high hardness, high melting factor, high flexible modulus, chemical deterioration resistance, and also wear resistance and has actually come to be one of the extensively used steel carbides. In reducing devices, chromium carbide powder normally plays a crucial duty as a surface area layer. In Fe-Cr-C alloy, chromium carbide is a critical rainfall phase, providing the material outstanding wear resistance. Chromium is a critical wear-resistant phase, while solidity, as a significant mechanical specification in the design of wear-resistant products, has yet to obtain a relatively exact result.

Chromium carbide (CnC) has a low solidity 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 primary features are that the carbide has a high space temperature level, thermal firmness, and also good wettability with steels such as CoNi. It is used in metal mold compounds.

Making chromium carbide by a mix of aluminothermic decrease as well as vacuum furnacing at temperature levels of 1500°& deg; C and above. A blend of chromium steel, chromium oxide as well as carbon is ready and after that packed into a vacuum heater. The stress in the heater is decreased as well as the temperature raised to 1500°& deg; C. The carbon reacts with the chromium oxide to form chromium metal as well as carbon monoxide gas, which is drained into the vacuum cleaner pumps. The chromium steel then integrates with the staying carbon to create the chromium carbide
