温暖的压缩和房间温度压缩被使用准备结合的 Nd-Fe-B 磁铁。结果显示磁铁的密度被压缩压力和温暖的压缩温度决定,而, ther-mosetting 温度几乎不能影响磁铁的密度。当 thermosetting 温度是 200 .The Br 时,磁铁的机械性质是最好, Hcb,并且(BH ) 温暖的压缩磁铁的最大比房间压缩的那些高。当温暖的压缩温度和 thermosetting 温度是不变的时,磁铁的密度随压缩压力的增加增加了,它导致了 Br 的增加,壁炉内部的一锅架,并且(BH ) 磁铁的最大和磁铁的 Hcj 的减少。当温暖的压缩温度和压缩压力是不变的时,磁铁的磁性随 thermosetting 温度的增加减少了。塑造磁铁的温暖的压缩的磁性比塑造磁铁的注射的那些好。
Warm compaction and room temperature compaction were applied to prepare bonded Nd-Fe-B magnets. The results indicated that the density of magnet was determined by the compaction pressure and warm compaction temperature, whereas, the thermosetting temperature could hardly affect the density of magnet. The mechanical properties of magnets were the best when the thermosetting temperature was 200 ℃. The Br, Hob, and (BH)max of warm compaction magnet were higher than those of room compaction. When the warm compaction temperature and thermosetting temperature were invariable, the density of magnet increased with the increase of compaction pressure, which resulted in the increase of Br, Hcb, and (BH)max of magnet and the decrease of Hcj of magnet. When the warm compaction temperature and compaction pressure were invariable, the magnetic properties of magnets decreased with the increase of thermosetting temperature. The magnetic properties of warm compaction molding magnets were better than those of injection molding magnets.
