Product Description
10Co4Cr tungsten carbide is a kind of tungsten carbide cobalt chromium powder, which is composed of WC10Co4Cr. It is another important wear-resistant spraying material after WC12Co. Compared with WC12Co powder, WC10Co4Cr coating is not only wear-resistant, but also has a certain corrosion resistance. WC10Co4Cr should be a good choice when working conditions include not only wear but also corrosion.
The inherent characteristics of WC Co coating are wear-resistant grain wear, erosion wear and micro vibration wear, while the introduction of Cr element provides corrosion resistance. This kind of material is a good substitute for hard chromium plating. When human beings have higher and higher requirements for the environment, hard chromium plating is on the decline, which sets up 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 compact, hard and wear-resistant. Suitable for supersonic spraying, plasma spraying and other processes. It is an ideal substitute for hard chromium plating. The coating has compressive stress, good corrosion resistance, wear resistance and erosion resistance, and high surface finish. It is used in wet corrosive environment, aircraft landing gear, paper making process, hydraulic cylinder and valve industries.
