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 the boiling factor is 3800 ℃. It has great wear resistance, corrosion resistance as well as oxidation resistance at high temperature level (1000 ~ 1100 ℃). Coming from a cermet.

Especially chromium carbide has many outstanding buildings, such as strong chemical stability, high solidity at room temperature level and thermal solidity, good resistance to acid and also alkali rust, good wear resistance, high melting factor, and great wettability with metals such as and also. In the metal carbide, the oxidation resistance of zui is high, as well as the oxidation temperature level is as high as. When chromium is utilized as a prevention, the grain development of concrete carbide can be properly managed. In addition, chromium carbide is not just an additive of eruptive bonding product with excellent wear resistance and a top quality cermet resources. It can additionally be made use of as spraying powder. For instance, spraying powder has great deterioration, oxidation, as well as use resistance at high temperatures. Because of its excellent qualities, chromium carbide has actually been widely made use of in the metallurgical industry, electronic industry, high-temperature immune covering, aerospace, as well as various other fields.

Chromium carbide has high hardness, high melting factor, high flexible modulus, chemical deterioration resistance, and wear resistance as well as has ended up being one of the extensively made use of steel carbides. In cutting tools, chromium carbide powder usually plays an important role as a surface area layer. In Fe-Cr-C alloy, chromium carbide is a vital precipitation phase, giving the material excellent wear resistance. Chromium is a crucial wear-resistant stage, while hardness, as a considerable mechanical criterion in the design of wear-resistant products, has yet to obtain a fairly accurate outcome.

Chromium carbide (CnC) has a reduced solidity of 1710 and also a density of 6.68 g. m), a thermal growth coefficient of 10.3 x 10 ~ K (20-100) and a thermal conductivity of 19.1 W.m-+. K-1. Its main features are that the carbide has a high area temperature, thermal hardness, and also great wettability with steels such as CoNi. It is used in metal mold and mildew substances.

Producing chromium carbide by a combination of aluminothermic decrease 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 afterwards packed right into a vacuum heating system. The stress in the heating system is minimized as well as the temperature boosted to 1500°& deg; C. The carbon responds with the chromium oxide to create chromium metal and also carbon monoxide gas, which is drawn off into the vacuum pumps. The chromium steel then integrates with the remaining carbon to develop the chromium carbide
