Kuumbwa kweSamarium Cobalt Permanent Magnets
Samarium cobalt inogara magineti ndeye isingawanzo pasi magineti, inonyanya kuumbwa nesimbi samarium (Sm), simbi cobalt (Co), mhangura (Cu), iron (Fe), zirconium (Zr) uye zvimwe zvinhu, kubva muchimiro chakakamurwa kuita 1. :5 mhando uye 2:17 mhando mbiri, ndeyechizvarwa chekutanga uye chechipiri chizvarwa chezvisingawanzo pasi zvechigarire magineti zvinhu. Samarium cobalt inogara magineti ine yakanakisa magineti zvivakwa (yakakwirira remanence, yakakwirira coercivity uye yakakwirira magineti simba chigadzirwa), yakadzika kwazvo tembiricha coefficient, yakakwirira sevhisi tembiricha uye yakasimba corrosion resistance, ndiyo yakanakisa tembiricha inodzivirira zvachose magineti zvinhu, inoshandiswa zvakanyanya mumicrowave zvishandiso, erekitironi. danda midziyo, yakakwirira-simba / yakakwirira-kumhanya motors, sensors, magineti zvikamu uye mamwe maindasitiri.
Basa re2:17 samarium-cobalt magineti
Imwe yeanonyanya kufarirwa samarium-cobalt magineti ndeye 2:17 samarium-cobalt magineti, akatevedzana magineti anozivikanwa neawo epamusoro magineti zvivakwa, achivaita sarudzo yekutanga yekushandisa inoda yakakwirira magineti simba uye kugadzikana.
Kubva pamaitiro ekuita, 2:17 samarium-cobalt magineti echigarire anogona kukamurwa kuita yakakwira-inoshanda nhevedzano, yakanyanya kugadzikana yakatevedzana (yakaderera tembiricha coefficient) uye yakakwirira tembiricha kuramba mutsara. Iyo yakasarudzika musanganiswa weakakwira magineti simba density, kugadzikana kwekushisa uye corrosion kuramba inoita samarium-cobalt magineti echigarire akanakira akasiyana maapplication, anosanganisira emagetsi motors, sensors, magineti couplings uye magineti separators.
Iyo yakanyanya magineti simba chigadzirwa renji yegiredhi rega rega iri pakati pe20-35MGOe, uye yakanyanya tembiricha yekushanda i500 ℃. Samarium-cobalt magineti echigarire ane yakasarudzika musanganiswa weyakadzika tembiricha coefficient uye yakanaka corrosion kuramba, yakakwira magineti simba density, kugadzikana kwetembiricha uye kusagadzikana kwekuora, zvichiita samarium-cobalt magineti echigarire akanakira akasiyana ekushandisa, anosanganisira emagetsi motors, sensors, magineti. couplings uye magnetic separators. Iwo magineti zvimiro zveNdfeb magineti pakupisa kwepamusoro anodarika magineti eNdFeb, saka anoshandiswa zvakanyanya mumhepo, nhandare dzemauto, kupisa kwakanyanya mota, ma sensors emotokari, akasiyana magineti madhiraivha, magineti pombi uye microwave zvishandiso. 2:17 mhandosamarium cobalt magineti dzakanyanya brittle, hazvisi nyore kugadzira kuita maumbirwo akaomarara kana kunyanya mashizha matete uye zvindori zvine madziro, mukuwedzera, zviri nyore kukonzeresa makona madiki mukugadzira maitiro, kazhinji sekunge zvisingakanganisi magineti zvivakwa kana mabasa, zvinogona kutorwa sezvigadzirwa zvinokwanisa.
Muchidimbu, samarium cobalt anogara magineti, kunyanya iyo yakakwira magineti simba density akateedzanaSm2Co17 magineti, inokosheswa zvakanyanya nekuda kweakanakisa magineti maitiro uye kugadzikana. Kugona kwavo kumira tembiricha yakakwira uye nharaunda dzakaomarara dzinovaita sarudzo yekutanga yekuda maapplication mumaindasitiri ese. Sezvo tekinoroji ichienderera mberi, kudiwa kwesamarium-cobalt magineti echigarire anotarisirwa kukura, achisimbisa chinzvimbo chavo sechinhu chakakosha chemazuva ano maindasitiri nekutengesa mashandisirwo.
