Abstract: The nano-SiC/Ni–P composite coatings (nSNCCs) were fabricated on the surface of Glass substrates with the assistance of different electromagnetic fields. Then, the deposition rates of the nSNCCs were calculated by the weighing method. Morphology, chemical composition and crystal structure were characterized by SEM, EDS and X-ray diffraction (XRD), respectively. Experimental results show that the nSNCCs are all built by the accretion of spherical co-deposition product of Ni solid solution and nano-SiC particulates. Moreover, at the same plating time, the deposition rates of the nSNCCs increase with the increasing magnetic strength, and reach the peak by 17.5g/h⋅m−2. Meanwhile, the spherical particle size and the spaces between spherical co-deposition decrease, which result in the formation of the dense layers. The addition of magnetic fields in preparation process not only promotes the deposition of the nSNCCs, but also has a great influence on the orientation of the deposited products, which is favorable for the formation of a compact and uniform composite coating.
