This work investigated the parallel magnetically assisted jet electrodeposition of Ni-Co-MoS2/Ni super hydrophobic composite coatings. As a comparison, the effect of the magnetic field on Ni-Co alloy coatings was analyzed. Then, micro/nano MoS2/Ni particles were further added to study the performance of Ni-Co-MoS2/Ni composite coatings under different concentrations of micro/nano particles. Research indicated that the Ni-CoMoS2/Ni composite coating surface exhibits coral like micro/nano structures, and the micro/nano structures became denser as the concentration of micro/nano particles increased. The superhydrophobic composite coatings were obtained without any chemical modification reagents. The contact angle of the superhydrophobic composite coating was as high as 153.2 degrees and the sliding angle was 8.7 degrees when the amount of micro/nano particles was added at 5 g/L. The coral like micro/nano structures of the composite coating provided additional air cushion to support surface water droplets and exhibited excellent self-cleaning performance. In addition, the composite coating also showed excellent corrosion resistance and wear resistance, which was still relatively intact after friction, only exhibiting few wears on coral like micro/nano structures, it still maintained a good silver mirror effect after friction. This work suggested that parallel magnetically assisted jet electrodeposition could fabricate superhydrophobic composite coatings with excellent performance.
