摘要：
The influence of Al and Nb addition on the corrosion behaviour of NdFeB permanent magnets is studied by Mossbauer spectrometry and X-ray diffraction. At 200-degrees-C, results show that Al and Nb slow the oxidation kinetics of the Nd2Fe14B phase, indicating an increase of the corrosion resistance due to these dopants.
