Webb4 nov. 2024 · How Electroplating Works. Electroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. A cell consists of two electrodes (conductors), usually made of metal, which are held apart from one another. The electrodes are immersed in an electrolyte (a solution). WebbFor the Ni–Cu–Ni multilayer coatings, the innermost Ni coatings have certain magnetic shielding effects on the substrate [25]. Therefore, in this work, to reduce the magnetic shielding effects on the properties of NdFeB, corrosion resistance and the electroplating of Cu–Ni/P multilayer coatings have been studied.
