The wide application of chromium carbide, due to its various advantages, is also a very popular product in the market. But it also has a lot of need to know when using knowledge, after all, there are many users do not understand these. The next small series for everyone to introduce some of the use of chromium carbide points?

Chromium carbide is a kind of high melting point inorganic material, which has good wear resistance, corrosion resistance and oxidation resistance in high temperature environment. It is widely used as thermal spraying material for metal surface protection, and is also commonly used as hard alloy grain refiner and other wear-resistant and corrosion-resistant parts. In fact, it can be used as an additive to cemented carbide (such as tungsten carbide-based cemented carbide grain refiners) for mining and machining. In addition, if used, it can also be used as a welding material additive. The welding rod made of it can be surfacing on the working surface of some mechanical equipment (such as coal mill, ball mill, jaw plate, etc.), and the service life of chromium carbide can be improved several times or more. A large number of thermal spray materials are used in metal surface protection processes. It is also found that its melting point is 1890 ℃, boiling point is 3800 ℃; it has good wear resistance, corrosion resistance and oxidation resistance in high temperature environment. Belongs to metal ceramic. Chromium carbide is widely used in aircraft engines and petrochemical machinery, which can greatly improve the service life of machinery. It is also commonly used as a grain refiner for wear-resistant and corrosion-resistant parts such as cemented carbide. Cr3C2-based cermets have excellent oxidation resistance at high temperatures.

Chromium carbide is used as an additive in tools made of cemented carbide to increase hardness by preventing the growth of large grains. [8] The main component of most cutting tools is tungsten carbide. Tungsten carbide is combined with other carbides such as titanium carbide, niobium carbide, chromium carbide, etc., and the product is sintered with a cobalt substrate during use. The formation of large grains in the composite is prevented, resulting in a fine grain structure with excellent hardness. Accidental formation of chromium carbides in stainless steels and other alloys can cause intergranular corrosion. In use, it can also resist the wear of thin films and semiconductor films; therefore, the chromium carbide we are talking about today can of course also add Cr3C2 to the production of cemented carbide, which can not only refine the WC grains, but also improve the strength and hardness of the alloy. In order to improve the corrosion resistance of the alloy, it is widely used as corrosion-resistant alloy structural materials (instruments, valves, seals, etc.) in industrial production. Chromium carbide is widely used in stainless steel, heat-resistant steel, corrosion-resistant steel, alloy steel and other special steel smelting and production.
