Influences of Process Conditions on Ni-P Electroless Plating on PVC Plastic
In this work, one step for sensitization and activation in pretreatment process is adopted. The influences of the temperature, pH value on electroless Ni-P plating on PVC plastic were discussed. The components and surface morphology of the coating were studied by using SEM and EDS. The results show that the optimum operating condition is temperature being 50～55 , the optimum pH value being 8.5. Under the optimal technical conditions, the deposits is smooth and uniformity. The adhesion between the deposits and the matrix is better, The deposit contains 97.68% (wt) Ni and 2.32% (wt)P by the analyses of energy disperse X-ray.
