石英光纤表面化学镀Ni-P-B工艺及其动力学
摘要
Orthogonal experimental method was used to investigate the effects of NiCI2•6H2O、NaH2PO2•H2O、KBH4、H2NCH2CH2NH2、3CdSO4•8H2O and temperature on Ni-P-B electroless plating on quartz optical fiber surface when the lightness and combination extent of Ni-P-B thin film were taken as the objective functions. The optimal values of the six factors above were determined as: 24 g•L^(-1), 10 g•L^(-1), 1.0 g•L^(-1), 24 mL•L^(-1), 0.6 mg•L^(-1) and 90℃, respectively. Single experimental method was applied to study the effect of the six factors on Ni-P-B deposition rate based on which the kinetic models for Ni-P-B deposition were established. The models were proven to be in a good accordance with the experimental results, which has certain reference value for the process adjusting and product controlling of the Ni-P-B deposition.
