Abstract

In this study the surface of WC POWDER particles coated by NI-P ELECTROLESS PROCESS and the effect of powder proportion immersed in Ni-P electroless bath and the activation pretreatment on the Nickel content was evaluated by X-Ray florescence analysis. To investigate the effect of powder proportion immersed in electroless bath, the activated powder with concentrations of 20 and 40 g/lit was added in electroless bath and the weight percent of Ni assessed to be 14.1 and 7.5% respectively. To evaluate the effect of activation process, WC POWDER with concentration of 20 g/lit was immersed in Ni-P electroless bath with and without activation process. By applying the activation process, the weight percent of Ni increased about 27%. An equation was proved to estimate the thickness of electroless layer. In this approach, the thickness of electroless layer in E20, E20P andE40P samples was calculated 0.08, 1.1 and 0.05 mm respectively. In XRD pattern of Ni-P coated WC, the W2C peaks were exhibited, because of the diffusion of hydrogen in structural defects.
