What is chromium carbide?
Chromium carbide (Cr3C2) is gray powder with metallic luster; Orthorhombic system; The density is 6.68g/cm3; The melting point is 1890℃ and the boiling point is 3800℃. It has good wear resistance, corrosion resistance and oxidation resistance at high temperature (1000~1100℃). Belonging to a cermet.
The applications of chromium carbide
Especially chromium carbide has many excellent properties, such as strong chemical stability, high hardness at room temperature and thermal hardness, good resistance to acid and alkali corrosion, good wear resistance, high melting point, and 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 an inhibitor, the grain growth of cemented carbide can be effectively controlled. Moreover, chromium carbide is not only an additive of explosive bonding material with good wear resistance and a high-quality cermet raw material. It can also be used as spraying powder. For example, spraying powder has good corrosion, oxidation, and wear resistance at high temperatures. Because of its excellent characteristics, chromium carbide has been widely used in the metallurgical industry, electronic industry, high-temperature resistant coating, aerospace, and other fields.
Chromium carbide has high hardness, high melting point, high elastic modulus, chemical corrosion resistance, and wear resistance and has become one of the widely used metal carbides. In cutting tools, chromium carbide powder usually plays a vital role as a surface coating. In Fe-Cr-C alloy, chromium carbide is a crucial precipitation phase, giving the material excellent wear resistance. Chromium is a critical wear-resistant phase, while hardness, as a significant mechanical parameter in the design of wear-resistant materials, has yet to get a relatively accurate result.
Chemical properties of chromium carbide
Chromium carbide (CnC) has a low hardness of 1710 and a density of 6.68g. m), a thermal expansion coefficient of 10.3x 10~K (20-100) and a thermal conductivity of 19.1W.m-+.K-1. Its main characteristics are that the carbide has a high room temperature, thermal hardness, and good wettability with metals such as CoNi. It is used in metal mold compounds.
How is chromium carbide made?
Producing chromium carbide by a combination of aluminothermic reduction and vacuum furnacing at temperatures of 1500°C and above. A blend of chromium metal, chromium oxide and carbon is prepared and then loaded into a vacuum furnace. The pressure in the furnace is reduced and the temperature increased to 1500°C. The carbon reacts with the chromium oxide to form chromium metal and carbon monoxide gas, which is drawn off into the vacuum pumps. The chromium metal then combines with the remaining carbon to form the chromium carbide.
