Why does chromium carbide have hardness

What is chromium carbide?

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

Specifically chromium carbide has many superb buildings, such as strong chemical stability, high solidity at area temperature and thermal firmness, good resistance to acid and alkali deterioration, great wear resistance, high melting point, and good wettability with metals such as and also. In the steel carbide, the oxidation resistance of zui is high, as well as the oxidation temperature level is as high as. When chromium is made use of as an inhibitor, the grain growth of cemented carbide can be effectively controlled. Furthermore, chromium carbide is not only an additive of eruptive bonding material with good wear resistance and also a top notch cermet resources. It can additionally be utilized as splashing powder. As an example, spraying powder has good corrosion, oxidation, as well as use resistance at high temperature levels. Due to its outstanding features, chromium carbide has been extensively utilized in the metallurgical industry, digital industry, high-temperature immune coating, aerospace, and various other areas.

Chromium carbide has high hardness, high melting point, high flexible modulus, chemical corrosion resistance, and also put on resistance and has become one of the commonly made use of metal carbides. In cutting tools, chromium carbide powder normally plays a crucial duty as a surface area covering. In Fe-Cr-C alloy, chromium carbide is an essential precipitation stage, providing the material exceptional wear resistance. Chromium is an important wear-resistant stage, while solidity, as a significant mechanical criterion in the layout of wear-resistant products, has yet to obtain a relatively precise result.

Chromium carbide (CnC) has a low firmness of 1710 and 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 characteristics are that the carbide has a high room temperature level, thermal solidity, as well as good wettability with metals such as CoNi. It is used in steel mold compounds.

Producing chromium carbide by a combination of aluminothermic reduction as well as vacuum cleaner furnacing at temperatures of 1500°& deg; C and above. A mix of chromium steel, chromium oxide and also carbon is prepared and then filled into a vacuum cleaner furnace. The pressure in the heater is lowered and also the temperature level increased to 1500°& deg; C. The carbon responds with the chromium oxide to form chromium metal and also carbon monoxide, which is attracted off into the vacuum cleaner pumps. The chromium steel then combines with the staying carbon to create the chromium carbide
