In this present work, Nickel-coated tungsten carbide powder was prepared by high concentration electroless nickel plating without noble metal catalysis and the WC/W2C based composites were successfully prepared by Selective laser melting (SLM). The Ni layers covering on tungsten carbide particles were controlled by the reagent type of complexing agent, stabilizing agent, and surfactant. When Trisodium citrate is used as a complexing agent, it has a well complexing effect on metal ions, but the other complexing agent is poor effect. Compared wit...
