What is chromium carbide? Chromium carbide(II) is a ceramic compound in various chemical compositions: Cr3C2, Cr7C3 and Cr23C6. Under standard conditions, it exists in the form of a grey solid. It is very hard and corrosion-resistant. It is also a fire-resistant compound, which means it can maintain its strength at high temperatures. These characteristics make it useful as an additive for metal alloys. When chromium carbide crystal is combined with the metal surface, it will improve the metal's wear resistance and corrosion resistance and maintain these properties at high temperatures. For this purpose, the common composition of Z hard and Z is Cr3C2.
Uses of chromium carbide 1. It is a high melting point material with good wear, corrosion, and oxidation resistance under high-temperature environments. It is made of cemented carbide particles made of nickel-chromium alloy. It can be used as a high temperature, wear resistance, oxidation resistance and acid resistance coating by plasma spraying. It is widely used in aircraft engines and petrochemical mechanical components, which can greatly improve the service life of machinery. It is also commonly used as a grain refiner of cemented carbide and other wear-resistant, Corrosion-resistant components. Cermets based on Cr3C2 have excellent oxidation resistance at high temperature 2. It is used for chromium carbide ceramics. Coarse chromium carbide is used as a melt-blown material to form a melt-blown coating on the surface of metals and ceramics, giving the latter wear-resistant, heat-resistant, corrosion-resistant and other properties. It is widely used in aircraft engines and petrochemical machinery components to improve mechanical life. It is also used for spraying semiconductor films.
Preparation of chromium carbide In preparing chromium carbide by physical vapour deposition, the metal chromium target is sputtered, and hydrocarbon gas is introduced as the carbon source to react with it. For example, in cn108330442b, the chromium carbide layer is prepared by reactive sputtering of the metal chromium target and acetylene, which improves the surface hardness of the metal substrate and improves the wear resistance. This method is simple, but the coating will contain some hydrogen, which is beneficial to titanium used in aerospace and nuclear technology; Zirconium alloy and other metal materials are extremely disadvantageous. In cn112376017a, the honeycomb chromium carbide coating was prepared by co-sputtering graphite and chromium targets. A buffer layer was introduced to improve the bonding between the coating and the substrate. However, this method resulted in a large amount of simple carbon in the coating, reducing the high-temperature oxidation resistance of the coating. Developing a new high-performance compact chromium carbide coating deposition process is one of the difficulties of the surface protection technology of chromium carbide.
Price of chromium carbide Chromium carbide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of chromium carbide. A large amount of large amount will be lower. The price of chromium carbide can be found on our company's official website.
