The commonly used ratio of nano tungsten carbide cobalt composite powder is 90/10, 94/6, purity is more than 99%, average particle size is 50nm, free carbon is less than 0.09%, oxygen content is less than 0.25%, remaining impurities content is less than 0.4%. It has excellent wear resistance and can be used as an abrasion resistant coating material and as a raw material for various cutting tools.
The nano tungsten carbide cobalt composite powder has excellent effects as an abrasion-resistant coating material. The coating prepared by rapid melting and rapid condensation technology keeps the nano-structure characteristics of the powder. Therefore, the performance of the tungsten carbide wear-resistant coating is significantly improved.
Nano tungsten carbide cobalt composite powder also has a wide range of applications, including micro-drills, various cutting tools, rock drills, dies, wear parts, bearings, and special-purpose tools such as slicing knife, medical scalpel, tape cutters, high performance saw blades, etc. These tools prepared by nano tungsten carbide cobalt composite powder can maintain its sharp cutting edge.
