Abstract

The invention provides a wear-resistant aluminum alloy nickel-plated composite material, the material includes an aluminum alloy substrate, a chemically replaced zinc layer, and a Ni-ZrC layer, wherein the ZrC is highly uniformly dispersed in a nano-inorganic material In the Ni coating, the size of the ZrC is 30-60nm, the self-corrosion potential of the material is -0.18V~-0.15V, and the self-corrosion current density is 6.5-8.2*10 ‑8 A / cm 2 , with a hardness of 900‑1000HV.

Description

technical field [0001] The invention relates to the technical field of surface modification of metal materials, in particular to a wear-resistant aluminum alloy nickel-plated composite material. Background technique [0002] Aluminum alloy has the advantages of light weight, high mechanical strength, and easy processing, but its disadvantages such as low hardness and poor wear resistance affect its application range and service life. The above-mentioned problems can be overcome by electrodepositing metal-based composite coatings containing second-phase particles on the surface of aluminum alloys. Among them, the nickel-based composite coating has been widely studied, and the functions of the added particles are different. For example, adding SiC, A12O3, diamond and other hard particles can increase the hardness of the coating, and adding polytetrafluoroethylene, hexagonal boron nitride, carbon nanotubes, MoS2, WS2, graphite and other solid lubricating particles can reduce t...
