Simulation and Properties of Ni/W-SiC Composite Coatings by Magnetic Field-Jet Electrodeposition

As part of this study, the optimal jet plating parameters were analyzed, and COMOL simulation software was used to simulate the magnetic field-jet electrodeposition processing area under various jet deposition conditions. In order to improve the performance of parts and components materials, different jet parameters were used to prepare Ni/W-SiC composite coatings on the surface of Q235 steel using the magnetic field-jet electrodeposition method. The effects of nozzle outlet diameter and jet distance on the flow field and deposition rate in the processing area of Ni/W-SiC composite coatings deposited by magnetic field-jet electrodeposition were studied. When the nozzle outlet diameter was Φ2 mm, Ni/W-SiC composite coatings had a smooth surface and a dense microstructure. The coatings had the lowest surface roughness and the highest coatings thickness; the roughness was 0.45 μm and the thickness of the coating was 0.162 mm. When the jet distance was 2 mm, Ni/W-SiC composite coatings were dense, SiC nanoparticles were uniformly distributed, and the surface morphology of Ni/W-SiC composite was smoother. At this point, the surface roughness of the coatings was at its lowest, measuring 0.31 μm, with a thickness of 0.15 mm.
