Abstract
Various surface modification techniques including electroplating, chemical vapour deposition (CVD) and laser surface melting have been applied to improve the poor corrosion resistance of NdFeB magnets. A range of heterogeneous double-layer coatings were prepared. The corrosion resistance of the surface-treated samples was compared with that of some commercially available coated samples using a aerated salt spray test. It was found that a double coating of Cr (topcoat)/Ni (undercoat) offered the best corrosion resistance.
