Micron tungsten carbide cobalt composite powder has uniform element distribution, fine powder particle size, narrow particle size distribution, etc. The average particle size of the powder is 50~150nm. It is widely used in the manufacture of superfine/nanocrystalline tungsten carbide tools and surface strengthening materials.
Properties
The physical properties of micron tungsten carbide cobalt composite powder are very different from those of conventional powders.
The non-metallic tungsten carbide phase and metal cobalt phase constitute a composite structure, not a simple mixture;
The vacuum density of the powder is large (up to 15.3g/cm3 for WC-6Co powder);
The powder is high purity non-oxide and oxidation and doping should be avoided during processing.
Applications
Micron tungsten carbide cobalt composite powder is widely used in the manufacture of ultra-fine/nanocrystalline carbide tools and surface-enhancing materials. The grain size of the tungsten carbide prepared by the method is 200~400nm. It has excellent properties such as high strength and high hardness. It is particularly suitable for the manufacture of high-performance extruded profiles, high wear-resistant cutting tools, surface coatings and other products.
