Samarium Cobalt Magnet Zipangizo



Kufotokozera

Monga gawo la gulu losowa lamatsenga losatha, ma samarium cobalt (SmCo) maginito amodzi amagwera m'mabanja awiri a zida. Amaphatikizapo zosowa zapadziko lapansi za sm1Co5 ndi Sm2Co17 ndipo zimatchulidwa kuti ndizinthu 1: 5 ndi 2:17. Pali mitundu itatu yopanga mitundu: maginito a smCo osakanizidwa, maginito a SmCo, ndi jekeseni yaumba ya smCo. Maginito a SmCo ndiwogwira ntchito kwambiri, kutentha kochepa kokhazikika kamene kamapangidwa ndi samarium ndi cobalt ndi zinthu zina zapadziko lapansi. Ubwino wake waukulu ndi kutentha kwa kutentha-300 digiri centigrade. Iyenera kupaka phukusi chifukwa ndizovuta kuyikidwapo ndi kuphatikizidwa. Maginito a SmCo amagwiritsidwa ntchito kwambiri pamagalimoto, wotchi, ma transducers, zida, zodziwikiratu, ma generator, radar, ndi zina.
 
Samarium Cobalt imakhala ndi malo ake pamalo otentha kwambiri kuposa neodymium, ngakhale mphamvu zake zazikulu ndizochepa. Mtengo wa zinthu za SmCo ndiwodula kwambiri, chifukwa chake SmCo imangolimbikitsidwa pokhapokha ngati magwiridwe ake ndi malo otentha kwambiri ndi nkhawa.
 
1.SmCo permanent magnet has high magnetic energy product and high coercive force. Its properties are better than Alnico, ferrite permanent magnet. Its max. energy product is up to 239kJ/m3(30MGOe), which is three times of that of AlNiCo8 permanent magnet, eight times of that of ferrite permanent magnet (Y40). So the permanent magnetic component made from SmCo material is small, light and stable in property. It is widely applied to electro acoustic& telecommunication apparatus, electric motors, measure meters, peg-top electronic watch, microwave apparatus, magnetic mechanism, sensor and other static or dynamic magnetic routes.
 
2.The tempie. wa maginito osatha a SmCo ndiwokwezeka ndipo amapita. Coeff. wotsika. Chifukwa chake ndioyenera kugwiritsidwa ntchito pa 300, kutentha kwakukulu.
 
3.SmCo maginito okhazikika amamva ndi bristle. Mphamvu yake yokhazikika, kulimba kotsika komanso kulimba kwachepa. Chifukwa chake sichoyenera chimango.
 
4.Chida chachikulu cha maginito osatha a SmCo ndi cobalt wachitsulo (CoY99.95%). Chifukwa chake mtengo wake ndiwokwera.


Mpikisano wa Mpikisano:
Makhalidwe a Samarium Cobalt Magnet

* Mphamvu zambiri zamagetsi zomwe zimakhala ndi kukhazikika kwabwino.
* Kugonjetsedwa kwakukulu ndi kutentha kwambiri, kutentha kwa Curie kochuluka kupitirira 800 ?? * Kuthekera kwabwino kwambiri kwa kutu, palibe kuyimitsa komwe kumafunikira kuti mutetezedwe pamtunda.
