“…They found that ZrO 2 nanoparticles formed a hard, wear-resistant framework in the coating, which significantly improved the microhardness of the coating. Xu [28] et al prepared a nanocrystalline Ni-Mo/ZrO 2 coating by means of the DC electrodeposition process and found that with the addition of ZrO 2 nanoparticles, the surface roughness of the alloy coating increased, and the hardness and wear resistance was further improved. Yan et al [29] prepared a Ni-Al-ZrO 2 composite coating with high wear resistance on aluminum alloy by means of pulse electrodeposition technology, which expanded the industrial application range of aluminum alloy.…”

To improve the wear resistance of the surface of the cotton picker spindle, a Ni-Co-ZrO2 composite coating with different ZrO2 nanoparticle concentrations was prepared using electrodeposition technology on the micro surface of spindle hook teeth, and the morphologies of the surface and cross-section, element contents, grain sizes, microhardness and friction coefficients of the Ni-Co-ZrO2 composite coating were obtained; a simulated wear test was conducted based on the independently developed spindle hook tooth wear device, and the morphologies and elemental distributions of the composite coating before and after wear were obtained; the effects of different ZrO2 nanoparticle concentrations (0, 2, 4, 6, 8 g/L) on the morphology, element content, grain size, microhardness, friction coefficient and wear resistance of the coating were discussed. The test results indicated that compared with Ni-Co coatings, Ni-Co-ZrO2 composite coatings featured a more compact coating structure, a greater coating thickness, and a smaller grain size. The presence of ZrO2 nanoparticles led to further improvement of the coating’s microhardness, friction coefficient and wear resistance. When the mass concentration of ZrO2 nanoparticles reached 4 g/L, the microhardness of Ni-Co-ZrO2 composite coating reached the maximum value, 545.4 Hv0.1, and the friction coefficient decreased to 0.06. At the same time, in the simulated wear test, the composite coating with this concentration had the smallest wear area and the highest wear resistance.
