Nickel Deposition on Pre-Electroless Plated Ni-P-B Coating on Quartz Optical Fiber in a Lanthanide Oxide-Added Watt Electroplating Bath

Abstract:

Lanthanide oxide was added into the common Watt bath to make a thick nickel on the Ni-P-B coating on the quartz optical fiber surface by response surface method. The experiment showed the optimum concentrations of NiSO₄•6H₂O, CH₃（CH₂）₁₁OSO₃Na and La₂O₃ as well as current density were separately 220g/L, 0.08g/L, 0.9g/L and 1.0 A/m² under which the deposition rate reached 24.2μm/h. The established model had an agreement with the experimental values and can be used to predict the deposition rate within the experimental range. The experiment also showed that the deposition rate, structure and other physical properties of the Ni coating prepared with addition of La₂O₃(0.9g/L) were greatly improved compared with the sample prepared without addition of La₂O₃ under same conditions.
