摘要

In this work, the cladless hot isostatic pressing (HIP) is performed on sintered NdFeB magnets. After the processing, the density of the magnets is slightly increased. The statistics of microstructure shows the growth of grains. The evaluation by X-ray diffraction shows that the alignment degree of grains decreases. These effects slightly improve the magnetic energy product, meanwhile bring about the deterioration of coercivity. Corresponding to the increase of density, the corrosion resistance checked by electrochemistry method becomes better after HIP processing.
