cobalt nano particles

      Cobalt particle is the best binder for cemented carbide. Although iron, cobalt powder, nickel powder generations have made some progress, still more than 90% of the carbide cobalt used as binder. In order to improve the organizational structure of carbide, improve performance and reduce the size of cobalt powder has very important significance. To reduce the average particle size of the binder powder can improve the transverse rupture strength, hardness and density. To use the ultra-fine cobalt powder manufacturing high-performance WC-Co cemented carbide, requests the cobalt nano particles average particle size to achieve to less than 500nm. In such particle size could produce excellent adhesive. With the small particle size Cobalt powder to make WC-Co whose abrasion resistance and crack resistance is much better than the alloy produced with coarse cobalt powder.
