Preparation and Thermodynamics of Nickel-Phosphor Deposition on Surface of Quartz Optical Fiber by Electroless Plating

The electroless nickel-phosphor deposition on quartz optical fiber surface was carried out by single factor test. The optimum NiSO4 center dot 6H(2)PO(2)center dot H2O, C3H6O2 and H3BO3 concentrations, pH value and temperature were determined lobe: 0.1331 mol/L, 0.3019 mol/L, C(3)H(6)O(2)0.3761 mol/L, H3BO3 0.4520 mol/L, 4.5 and 84 degrees C, respectively. Scanning electron microscope, stereomicroscope and thermal shock rest were applied to measure the morphology and strength of adhesion of the deposited Ni-P coating. The result showed that a desired Ni-P coating with good smoothness and adhesion was prepared under the optimal conditions. The thermodynamic models were established and proven by the current study.
