style="text-indent:25px">釹鐵硼磁鐵的作用有那些？釹鐵硼磁鐵性能優(yōu)異、原料豐富、市場(chǎng)價(jià)格近幾年也波動(dòng)不大。在應(yīng)用于微特電機(jī)、永磁儀表、電子工業(yè)、汽車工業(yè)、石油化工、核磁共振裝置、傳感器，音響器材、磁懸浮系統(tǒng)、在醫(yī)療設(shè)備和磁性傳動(dòng)機(jī)構(gòu)方面應(yīng)用廣闊。磁性材料類比：鐵氧體：性能低和中，價(jià)格較低，溫度特性良，耐腐蝕，性能價(jià)格比好。釹鐵硼：性能較高，價(jià)格中，強(qiáng)度好，不耐高溫和腐蝕。釤鈷：性能高，價(jià)格較高，脆，溫度特性優(yōu)，耐腐蝕、鋁鎳鈷性能低和中，價(jià)格中，溫度特性優(yōu)，耐腐蝕，耐干擾性差。SmCo，鐵氧體，釹鐵硼磁鐵可分為燒結(jié)釹鐵硼和粘結(jié)釹鐵硼，燒結(jié)磁性能高，成型較差，粘結(jié)磁鐵成型性好，性能降低很多。AlNiCo可用鑄造和燒結(jié)方法制造，鑄造磁鐵性能較高，成型性較差好，燒結(jié)磁鐵較低，成型性較好。</p><p style="text-indent:25px">釹磁鐵（Neodymiummagnet）也稱為釹鐵硼磁鐵（NdFeBmagnet），是由釹、鐵、硼（Nd2Fe14B）形成的四方晶系晶體。于1982年，住友特殊金屬的佐川真人發(fā)現(xiàn)釹磁鐵。這種磁鐵的磁能積（BHmax）大于釤鈷磁鐵，是當(dāng)時(shí)全世界磁能積較大的物質(zhì)。后來(lái)，住友特殊金屬成功發(fā)展粉末冶金法（powdermetallurgyprocess），通用汽車公司成功發(fā)展旋噴熔煉法（melt-spinningprocess），能夠制備釹鐵硼磁鐵。這種磁鐵是現(xiàn)今磁性僅次于相對(duì)零度鈥磁鐵的永久磁鐵，也是較常使用的稀土磁鐵。釹鐵硼磁鐵被普遍地應(yīng)用于電子產(chǎn)品，例如硬盤、手機(jī)、耳機(jī)以及用電池供電的工具等。為了避免腐蝕的損害，使用時(shí)需要在永磁材料表面做保護(hù)處理，例如用金、鎳、鋅、錫進(jìn)行電鍍，以及表面噴涂環(huán)氧樹脂等。電動(dòng)機(jī)的外型和尺寸可以靈活多變等明顯特點(diǎn)，所以稀土永磁電機(jī)近幾年來(lái)得到迅猛發(fā)展。</p><div
