Corrosion behavior of sintered NdFeB permanent magnet with modified microstructure and different rare earth content

Liu Weiqiang

Abstract

Sintered NdFeB magnets with different rare earth content were prepared by Spark Plasma Sintering technique.Magnets with same composition were produced using conventional sintering method for comparison.The corrosion behavior of the magnets in the autoclave were investigated.Compared with conventional sintered NdFeB magnets,the SPS magnets process better corrosion resistance.The sintered NdFeB magnets exhibit excellent corrosion resistance with the reduction of rare earth content.
