Problems solved by technology

[0003]The traditional composite electrodeposition technology uses direct current, which is less effective in increasing the cathode current density, suppressing side reactions, reducing impurity content, and improving current distribution.
At the same time, due to the complexity of the multi-component composite electrodeposition electrolyte system, the stability is poor and precipitation is easy to occur.
The greater van der Waals attraction on the surface of the particles in the electrolyte leads to serious agglomeration. When only mechanical stirring is used to ensure the suspension of the particles, a higher stirring rate is required, which also leads to difficulties in particle deposition.
Therefore, the prepared composite material has many structural defects, and it still cannot meet the requirements of use in harsh environments that require wear resistance, corrosion resistance, and high temperature oxidation resistance.

Abstract

The invention provides a nanometer granule reinforced metal-based amorphous composite material and a preparation method thereof. In the method, the Ni-W-P / CeO2-SiO2 amorphous composite material of which the thickness is between 54 and 251 micrometers is prepared on the surface of ordinary carbon steel in electrolyte by utilizing dipulse electrolytic deposition for 1.5 to 6 hours under the action of ultrasound, mechanical stirring and the common dispersion of two surfactants. In the nanometer granule enhanced metal-based amorphous composite material, the electrolyte is high in stability, homogeneous plating capacity, current efficiency and deposition rates. CeO2 and SiO2 nanometer granule reinforced phases in the amorphous composite material are dispersed, the sizes of matrix metal granules ranges from 1 to 2 micrometers, and the composite material has a compact tissue structure, a thick deposition layer and high plating microhardness, is combined with a matrix firmly and can be used as surface functional plating layers of equipment parts of metallurgy, chemical industries, tobaccos, machines and the like.
