Samarium Cobalt Magnet Material



Whakaahuatanga

Hei waahanga o nga roopu whenua onge mo nga kowhatu ka mau tonu, ka uru te kaha o te aukati samarium kobalt (SmCo) ki nga whanau e rua. Kei roto i a raatau nga whenua onge noa a Sm1Co5 me Sm2Co17 ka kiia ko nga rauemi 1: 5 me 2:17. E toru nga mahinga hangahanga rerekee: te koki SmCo peita, kua oti te whakakaha a SmCo, me te miihini i te aukati a SmCo. He kaha te mahi a te poreko SmCo, te iti o te pāmahana iti i hangaia e te samarium me te cobalt me ​​etahi atu taonga onge-whenua. Ko tana painga nui ko te mahi nui o te pāmahana-300 tohu centigrade. Me pania te mea he uaua ki te horo me te whakatipu. E whakamahia whānuitia ana te kōkiri a SmCo i roto i te motuka, te mataaratanga, nga kaiwero, nga taonga, ko te keehi, he kaiwaiata, he puare
 
Ko Samarium Cobalt kei te pupuri i ona rawa paerewa kia nui ake te paerewa nui rawa atu i te neodymium, ahakoa he iti noa iho te rahi o te strengh. Ko te utu mo nga rauemi a SmCo te mea nui rawa atu, na reira ka tūtohu a SmCo i te wa e tika ana te mahi o te mahinga pāmahana nui.
 
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 curie temp. Ko te kaha o te aukati pono a SmCo he tino tiketike. Coeff. he iti. Na e tika ana mo te whakamahi i te 300, te wa tiketike.
 
3.SmCo maurongo tonu ka rangona me te kaanene. He pakari tona kaha, te kaha tensile me te kaha peita. No reira kaore e tika ana mo te anga.
 
4. Ko te whakaurunga matua o te aukati tūturu a SmCo ko te kopa kakano (CoY99.95%). Na he utu nui tona utu.


Whakamahia te Whakauru:
Ko nga ahuatanga o Samarium Cobalt Magnet

* Tino whakarihariha tino kounga ki te pūmautanga pai.
* Te ātete kaha ki te pāmahana teitei, ko te pāmahana o te nuinga o te Curie he nui ake i te 800 ?? * He raupaparenga ātete aukati, ka hiahiatia he paninga hei tiaki i te mata.
