To improve the wear resistance of the surface of the cotton picker spindle, a Ni-Co-ZrO2 composite coating doped with ZrO2 nanoparticles was prepared by electrochemistry on the micro surface of spindle hook teeth. The effects of different ZrO2 nanoparticle concentrations on various parameters of the coating were discussed. The test results indicated that 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 wear resistance. When the mass concentration of ZrO2 nanoparticles reached 4 g/L, the wear resistance was at its highest. View this paper
