What is Chromium Carbide? Chromium carbide (Cr3C2), chromium tricarbonyl, belongs to an inorganic compound with a molecular weight of 180.01. Its appearance is grey powder metallic lustre, is an orthorhombic crystal system, a=2.821, b=5.52, c=11.46. A melting point of 1890℃ and a boiling point of 3800℃. The microhardness (load 50 g) is 2700kg / rnrn 2, and the thermal expansion coefficient is 10.310-6 / K. Usually in 1000~1100℃ high-temperature environment with good wear resistance, corrosion resistance, oxidation resistance and other characteristics, it is a kind of metal ceramics. Its production method is the metal chromium powder carbonization method: the carbon black according to 13.5%~64% in the proportion of (quality) (more than the theoretical combination of carbon amount 11.33%) and with electrolytic chromium crushing into 325 purpose metal chromium powder, with a ball mill for dry mixing as raw material. Add 1% to 3% stearic acid as a lubricant for moulding. Pressor with pressure above 1 T / cm2. Put the pressurized forming powder into the graphite plate or crucible, with a taman furnace or induction heating furnace, in the hydrogen flow (hydrogen dew point in-35℃), heat to 1500~1700℃, and maintain for 1h, so that the chromium carbonization reaction, chromium carbide, after cooling, chromium carbide.
Main uses of Chromium Carbide Chromium carbide is a kind of high-temperature environment that has good wear resistance, corrosion resistance, oxidation resistance high melting point advantages of the material; it can interact with a nickel-chromium alloy, make carbide particles using plasma spraying method, can be used as high-temperature resistance, wear resistance, oxidation resistance and acid resistance coating, widely used in other places, such as aircraft engine and petrochemical machinery devices, this can greatly improve the life of machinery. In addition, it is also commonly used as a carbide grain refiner and other wear and corrosion-resistant elements.
Metal ceramics based on Cr3C2 can also be used in chromium carbide ceramics because of their excellent antioxidant properties at high temperatures. Coarse-grain chromium carbide is a melt-blown material in the metal and ceramic surface to form a melt-blown coated film, giving the latter wear resistance, heat resistance, corrosion resistance and other properties, widely used in aircraft engines and petrochemical machinery devices to greatly improve the mechanical life. Also used for spraying semiconductor film, semiconductor materials are the main materials of microelectronics and optoelectronic devices, especially the large-scale integrated circuit chip element integration is getting higher and higher, the size of the components is getting smaller and smaller, the semiconductor film is the basic material of this kind of devices.
