Samarium Cobalt Magnet Zvinhu



tsananguro

Sechikamu cheshoma yepasi boka remagineti anogara aripo, samarium cobalt (SmCo) magineti anowira mumhuri mbiri dzezvinhu. Zvinosanganisira zvisingawanzo pasi Sm1Co5 uye Sm2Co17 uye zvinonzi 1: 5 uye 2:17 zvinhu. Kune matatu matatu akasiyana maitiro ekugadzira: sintered SmCo magineti, yakasungwa SmCo magineti, uye jekiseni kuumbwa SmCo magineti. SmCo magineti yakanyanya kuita, yakaderera tembiricha coefficient zvachose kuita samarium uye cobalt nezvimwe zvisingawanzo-zvepasi zvinhu. Kubatsira kwaro kukuru kwakanyanya kushanda tembiricha-300 degree centigrade. Inoda kuvezwa nekuti inorema kubviswa uye kusanganiswa. SmCo magineti inoshandiswa zvakanyanya mumota, wachi, transducers, zviridzwa, positional detector, jenareta, radar, nezvimwe.
 
Samarium Cobalt inobata yakajairika chivakwa mumatunhu akakwirira ekushisa kupfuura neodymium, kunyange hazvo simba rayo rakanyanya iri shoma. Mari yeSmCo zvinhu ndiyo inodhura kwazvo, saka SmCo inokurudzirwa chete kana kuita kwayo kuri kwakanyanya tembiricha nharaunda kuri kunetsekana.
 
1.SmCo zvachose magineti ine yakakwira magnetic simba chigadzirwa uye yakakwira yekumanikidza simba. Izvo zvivakwa zviri nani kupfuura Alnico, ferrite zvachose magineti. Yayo max. Simba chigadzirwa chinosvika 239kJ / m3 (30MGOe), inova katatu iyo yeAlNiCo8 zvachose magineti, kasere keiyo yeferrite zvachose magineti (Y40). Saka chigadziko chemagineti chinogadzirwa kubva kuSmCo zvinhu zvidiki, chakareruka uye chakatsiga mune chivakwa. Inoshandiswa zvakanyanya kune electro acoustic & telecommunication zvishandiso, magetsi emagetsi, kuyera metres, hoko-yepamusoro yemagetsi wachi, microwave zvishandiso, magnetic mashini, sensor uye imwe static kana ine simba magineti nzira.
 
2.Curie temp. of SmCo zvachose magineti iri kumusoro uye ayo temp. Coeff. yakaderera. Saka inokodzera kushandiswa pa300, yakanyanya temp.
 
3.SmCo zvachose magineti anonzwa uye bristle. Kuomarara kwayo, kusimba kwesimba uye simba rekudhinda rakaderera. Saka haina kukodzera hwaro.
 
4.Chigadziro chikuru cheSmCo magineti zvachose isimbi cobalt (CoY99.95%). Saka mutengo wayo wakakwira.


Kukwikwidza Kunobatsira:
Hunhu hweSamarium Cobalt Magnet

* Yakakwirira kwazvo magineti zvinhu zvine kugadzikana kwakanaka.
* Kudzivirira kwakanyanya kune yakanyanya tembiricha, Curie tembiricha yevakawanda inopfuura 800 ?? * Kwakanaka ngura kuramba kugona, hapana kupfeka kunodiwa pamusoro pekudzivirira.
