Abstract

In this paper,the NdFeB permanent magnet prepared by added elememts,hydrogen demolish and sintering process is investigated.The results show that by addition of Dy and Cu element can improve the coercivity,HD technology can increased remanence and improve the square degree of remanence curve,appropriate sintering processing can enhanced the density and remanence of magnet.Combination with these technologies can obtain the best magnetic properties.
