Thick Nickel Coating on Surface of Quartz Optical Fiber by Electrochemical Deposition Method

Abstract:

Electrochemical deppsition methods (electroless plating and electroplating) were used to deposit a thick nickel on surface of quartz optical fibers. A thin Ni--P film was firstly to be deposited on the fiber by electroless plating. Then a thick Ni coating with thickness of about 1.7 mm was deposited on the Ni-P film,as a substrate, by electroplating. The effects of the concentrations of NiSO₄·6H₂O, NaH₂PO₂·H₂O , C₃H₆O₂ , H₃BO₃ , pH value and temperature on the quality of Ni-P coatings were investigated and their optimal values were determined by orthogonal test method..The effects of concentrations of NiSO₄·6H₂O and C₁₂H₂₅―OSO₃Na and current density on Ni deposition were studied and the optimum technical conditions were discussed. Under the optimal conditions, the thin Ni-P film possessed good smoothness and strong adhesive force and the Ni-coating had good quality with fine Ni crystals and uniform surface.
