摘要
对采用添加元素、氢破和烧结工艺制备烧结钕铁硼永磁体进行了研究,结果表明,添加Dy和Cu可以提高磁体的矫顽力,氢破工艺可以提高磁体剩磁以及改善剩磁曲线的方形度,合适的烧结温度可以提高磁体的密度和剩磁.将这三项优化组合可以提高磁体的最大磁能积.
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.
