Abstract

This invention is about the preparing method of Ni-P alloy base composite deposited layer which contains nano SiO2 microns. The invention uses electrodeposition plating, and the electroplate liquid is made up of : NiSO4.6H2O 300g/L, NiCl2.6H2O 45g/L, H3BO3 40g/L, H3PO3 15g/L. The value of PH is 1-2, and the solution is distilled water or de-ionized water. Besides, nanometer SiO2 microboulders which have been treated should be added, and the dosis should be 10 g/L. Before the microboulders are added, in the method of pulse electrodeposition plating, the positive pole should be large square of pure Ni plate, while the negative pole is the body which will be plated with. During the process of plating, pulse electricity goes into the solution. The average electricity density is 5A/square decimeter, while the impulse width is ton = 1 ms, and the duty ratio is 1 : 7. What is more, the temperature of the electroplate liquid should be kept as 60 deg.C. At last, we can get the Ni-P alloy base composite deposited layer which contains nanometer SiO2 microns on the metal substrate material. This composite layer made in this invention has high hardness, while the layer is homogeneous and smooth, and the pattern structure is also quite satisfactory.
