摘要：

Although NdFeB magnets exhibit outstanding magnetic properties, they have suffered from poor corrosion resistance in humid air. Because of this, various problems occur such as degradation of magnetic properties and/or contamination of the magnetic circuits. The corrosion rate of NdFeB magnets is found to vary with 0, C, and N contents, and to reach the minimum when these elements are within the ranges: O > 0.6% (preferably 0.6 to 1.2%), C = 0.06 to 0.14%, N = 0.05 to 0.10%. © 1990 IEEE
