Abstract :In this study, the chemical plating parameters for Ni-P-acetylacetonate-TiO 2 composite particles and the corrosion resistances of the deposition layer obtained by electroless plating are investigated. The effects of the TiO 2 concentration, process time, temperature, and pH of the plating materials are examined, and optimal parameters are determined. The corrosion resistance of samples obtained by Ni-P-acetylacetonate-TiO 2 composite plating is assessed by comparison to a Ni plating layer, and it is found to be superior to that of Ni-P plating layers in a 3.5% NaCl salt spray, as well as in 15% H 2 SO 4 and 20% HCl solutions. The origin of this corrosion resistance in composite plating layers is discussed.
