palladium-free and environmentally friendly surface activation process for electroless nickel plating on PVC was developed by applying a chitosan-based hydrogel film to modify the poly(vinyl chloride) (PVC) surface by chemical bonds. The hydrogel layer was used as the chemisorption sites for nickel, and the nickel nuclei could initiate the subsequent electroless nickel plating onto the PVC surface......
successfully by using electroless plating.Effects of active solutions,plating time,reaction temperature,and the components of the plating bath on the Ni-P coating were investigated systematically.Moreover... the deposition rate of Ni effectively.The optimized plating bath and reaction conditions improve both the plating speed and the coverage rate of Ni-P electroless plating on the diamond......

electroless nickel plating and zinc immersion. It can be noted that in many previous reports on the electroless plating on magnesium alloys [18, 19], the nickel ions were provided by basic nickel carbonate in the plating bath. The pretreatment of electroless Ni-P deposition on magnesium alloys is discussed in relative reports, in which chromate is used in acid pickling. However, basic nickel carbonate......
