摘要

The possibility of four-layer (Ni – Cu – Ni – Sn) electroplating and epoxy paint coating of a NdFeB magnet from a hard magnetic alloy used in wind generators is considered. The corrosion-protective effect of various paint coatings on the magnet in aggressive environments is determined. It is shown that the electroplate layuer should have a thickness of at least 20 µm and the epoxy paint coating should be no thinner than 15 µm.
