| Abstract: | Composite electrodeposits of nickel-cobalt-tungsten carbide were prepared by adding tungsten carbide particles in the nickel-cobalt alloy solution. The effect of suspended tungsten carbide particles, bath temperature and cathodic current densities on the content of tungsten carbide in the electrodeposits was studied, the preferred plating parameters were also optimized by orthogonal test.The morphology of obtained deposits were analyzed by means of scanning electronic microscopy. Compared with nickel-cobalt deposits,nickel-cobalt-tungsten carbide composite deposits have refined grain size and increased surface roughness. |
