Influence of Stabilizer on the Behavior of Electroless Ni-P Solution and Anti-Corrosion of Electroless Ni-P Coating

The influence of different kinds of stabilizer on the behavior of electroless Ni-P solution and anti-corrosion of electroless Ni-P coating was studied. The results showed that KI had superiority in stability and longevity of plating solution and anti-corrosion of coating; The defects and the rate of porosity were less;Pb~(2+) had good stability in plating solution,but longevity of plating solution and anti-corrosion were worse.H_2NSCN was worst in stability and longevity of plating solution and anti-corrosion of coating ;The defects and the rate of porosity were more. It had been learned that the rate of porosity and morphology of the coating were one of the factors that influent anti-corrosion of electroless plating.The defects was less, the corrosion resistance was better.
