摘要：
Corrosion behavior and damage micrography of sintered NdFeB in HNO3 + HF mixing solution were studied by means of SEM, EDS, E-t curve, Tafel curve and EIS. The results show that the general corrosions in mixing solution mainly take place on the matrix phase and intergranular Nd-rich phase, after that the Nd-rich phase still netted-distributed on grain boundary.
