結果表明焙燒溫度是影響產物結構性能的最重要的因素，最佳焙燒溫度為500 ，溫度小於200不能形成完整的尖晶石結構，而焙燒溫度超過500產物會發生分解；綜合考慮焙燒時間最佳為8小時；溶液ph值也是影響產物性能的因素之一，實驗證明前驅體合成ph = 9 . 0最佳；另外不同的原料也會影響產物的結構，考察了不同鋰源的影響，選擇li _ 2co _ 3為最佳鋰源。The microwave magnetic sintering can not only lower the sintering temperature and shorten the sintering time, but also decrease the micro - grain size of magnets and make intergranular phase and grain boundary of main phase distributed well. the abnormal grain growth was found in conventional sintered ndfeb magnets, which may be due to the greater particle size and uneven distribution of powder, and higher sintering temperature and longer sintering time. of course, the abnormal grain growth would deteriorate the magnetic properties
微波磁場燒結的不但降低燒結溫度，縮短燒結時間，而且使磁體整體加熱，受熱更均勻，因而磁體晶粒更細小，並且主相晶粒邊界趨于規則化，晶間相的分佈更均勻；在常規燒結的磁體中則出現了晶粒異常長大現象，造成這一現象的原因，一方面可能是燒結溫度過高或燒結時間過長，另一方面可能是磨製的粉體均勻性較差，存在的大顆粒被許多細小顆粒包圍，在燒結過程中，大顆粒不斷吞併小顆粒，逐漸長大，而異常長大的晶粒自然會導致磁體性能的惡化。In basis of integer bush, the flange bush adopt high speed friction jointing, the materil are alluse 10 steel bracking, the surface sinter cupbsn 10 - 10tin and copper powder, have enough carrying capability and longer using life, not easy to flake off. suitable for engineer mechanism, panzer, train, pile driver, take the place of bronze cover, save the costs greatly, make the useful life longer
