WC-10Co4Cr tungsten carbide alloy powder tungsten carbide coated cobalt composite spherical tungsten carbide

       

WC-Co coatings have high density, good erosion resistance and high bonding strength with the substrate. The coating is widely used in aerospace, metallurgy, machinery and other fields [1-2] to enhance the wear resistance of the base metal and the repair of worn parts. Introducing a certain amount of Cr into the WC-Co coating can not only improve the corrosion resistance of the coating, but also improve the erosion resistance of the coating. Its composition is WC10Co4Cr, which is another important wear-resistant spraying material after WC12Co. Compared with WC12Co powder, WC10Co4Cr coating is not only wear-resistant, but also has certain corrosion resistance. When the working conditions are not only worn, but at the same time In the case of corrosion, WC10Co4Cr should be the best choice. The inherent characteristics of WC-Co coating are wear resistance, erosion wear and fretting wear. After the introduction of Cr element, it provides corrosion resistance. This type of material is the best substitute for hard chrome plating. Under the situation of higher and higher environmental requirements, hard chromium plating is in decline, which has built a platform for the wide application of WC10Co4Cr. It is recommended to use supersonic flame spraying. The coating can produce compressive stress on the substrate, with high bonding strength, smooth and dense, hard and wear-resistant. Suitable for supersonic spraying, plasma spraying and other processes. An ideal substitute for hard chromium plating. The coating exhibits compressive stress, good corrosion resistance, abrasion resistance and erosion resistance, and high surface finish. It is used in wet and corrosive environments, aircraft landing gear, papermaking technology, hydraulic cylinders and Valve industry.
