摘要

We studied the parameters influencing the chemical plating deposition rate of Ni-P TiO2 nanoparticle composite layers and the corrosion resistance of the resulting layers. The amount of TiO2 added, plating time, temperature and pH values were factors in a four-factor three-level orthogonal test; the parameters influencing the deposition rate of the Ni-P TiO2 nanoparticle composite plating layer were optimized. A specimen featuring the composite plating layer was prepared under the optimized conditions and its corrosion resistance was compared with those of a Ni-P plating layer and a carbon steel matrix. Our results indicated that the corrosion resistance of the Ni-P TiO2 nanoparticle composite plating layer was better than that of the Ni-P plating layer in the 3.5% NaCl solution, and the corrosion resistance of the Ni-P plating layer was slightly higher than that of the Ni-P TiO2 nanoparticle composite plating layer which immersed in the 10% H2SO4 and 15% HCl solution. Furthermore, both these layers showed better corrosion resistances than that of the carbon steel matrix. The corrosion resistance mechanism of the nanometer composite plating layer was discussed.
