Abstract Surface morphologies,ingredients and structure of electroless plating Ni-P alloy coatings were investigated using field emission scanning electron microscope,X-ray photoelectron spectrometer and X-ray diffraction instrument,the corrosion behavior of Ni-P alloy coatings in Na2S solution was studied by potentiostatic polarization method and the corrosion rate of Ni-P alloy coatings was measured in different concentration of Na2S solutions at different temperatures by gravimetric method.Experiment results indicate that the amorphous Ni-P plating is deposited with cellular structure on the surface.In the same concentration of Na2S solution,the passivation area of the anodic process of corrosion reaction of the Ni-P alloy coatings narrowed gradually with increasing temperature.
