Our nanometer cobalt tungsten carbide WC-CO has the advantages of simple preparation process, low cost, large output and very high performance-price ratio. Technically, the composition of nanocrystalline WC-Co composite powder can be designed according to the actual needs, and some other alloying elements and grain growth inhibitors can be added, and their contents can be accurately controlled. The content of impurities such as oxygen in the prepared nano WC-CO powder is low.

Nanostructured WC-Co has been used as protective coating and cutting tool. This is because nano-structured WC-Co is obviously superior to ordinary coarse-grained materials in hardness, wear resistance and toughness. Among them, the mechanical properties are improved by about one order of magnitude, and may be further improved. High-energy ball milling or chemical synthesis of WC-Co nano-alloy has been industrialized. Chemical synthesis includes three main steps: preparation and mixing of initial solution; Spray drying to form raw powder with uniform chemical properties; And then transformed into nanocrystalline WC-Co powder by fluidized bed thermochemistry. Spray drying and fluidized bed conversion have been used for mass production of metal carbide powders. The latest research shows that nano-WC-Co composite powder shows good effect as wear-resistant coating material. The coating prepared by thermal spraying technology with rapid melting and rapid condensation keeps the nano-structure characteristics of the powder, thus significantly improving the performance of cemented carbide wear-resistant coating.
