摘要

研究考虑了对风力发电机中使用的硬磁合金钕铁硼磁体进行四层（镍-铜-镍-锡）电镀和环氧涂料涂层的可能性。确定了各种涂料涂层在侵蚀性环境中对磁体的腐蚀保护效果。结果表明，电镀层的厚度至少应为 20 µm，环氧涂料涂层的厚度不应小于 15 µm。

Investigation of the Effect of Ni – Cu – Ni – Sn Four-Layer Electroplate and Epoxy Paint Coating on Corrosion Properties of NdFeB-Base Magnet

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.
