The optimum condition in hydrogen desorption pressure is p = 800 - 100000pa . comparing the magnets prepared by traditional ball milling process , the magnets prepared by hydrogen desorption have lower residual magnetization and maximum magnetic energy product 最佳的脱氢气压在800 - 100000pa之间hd法制备的烧结ndfeb永磁体的剩磁和最大磁能积比传统bm工艺稍低。
According to study on magnetic parameters of the bounded ndfeb magnets : coercive force ( hc ) , residual magnetism intensity ( br ) , ( bh ) max . the residual magnetism intensity ( br ) and ( bh ) max of the bounded ndfeb magnets have not been evidently changed between that of cladded and non - cladded ndfeb magnetic powders 能够改善ndfeb磁体的导电性能的目的。浙江工业大学硕士学位论文包覆前后的粘接ndfeb磁体的矫顽力有不同程度地降低;而最大磁能积和剩余磁感应强度却变化不大。
