| Abstract: |
| To further determine the effects of the pH value to chemical plating Ni-P alloy on the magnesium alloys, using scanning electron microscope (SEM), energy spectrometer (XPS), microhardness device as well as polarization curve and so on, analysis pattern and the performance of plating. The result indicates that the pH value influences the coating performance greatly, as the pH value is very low, it is difficult to plate, the pattern is best when the pH value is 8, the content of phosphorus reduces with the increasing of pH value; in certain scope, hardness reduces with the increasing of the PH value; when the PH value is 4，the corrosion electric potential of plating is highest and gets to - 0.92 volt, the corrosion resistance is best. |
