Samarium Cobalt Izixhobo zeMagnet



inkcazelo

Njengenxalenye yeqela elinqabileyo lomhlaba loomazibuthe abasisigxina, iimagnethi ze-samarium cobalt (i-SmCo) ziwela kwiintsapho ezimbini zezixhobo. Babandakanya umhlaba onqabileyo weSm1Co5 kunye neSm2Co17 kwaye kubhekiswa kubo njenge-1: 5 kunye nezixhobo ze-2: 17. Kukho iinkqubo ezintathu ezahlukeneyo zokuvelisa: umazibuthe weSmCo odibeneyo, umazibuthe weSmCo odibeneyo, kunye nenaliti yokubumba iSmCo magnet. SmCo umazibuthe ukusebenza eliphezulu, lobushushu lomlingani eliphantsi esisigxina eyenziwe samarium kunye ayibe kunye nezinye izinto ezinqabileyo-zomhlaba. Olona luncedo lwayo kukusebenza okuphezulu kweqondo lobushushu-i-300 degree centigrade. Kufuneka ifakwe kuba kunzima ukukhutshwa kunye ne-oxidized. Umazibuthe weSmCo usetyenziswa ngokubanzi kwimoto, iwotshi, ii-transducers, izixhobo, indawo yokujonga izinto, umvelisi, iradar, njl.
 
I-Samarium Cobalt ibambe ipropathi yayo esemgangathweni kumaqondo obushushu aphezulu aphezulu kune-neodymium, nangona amandla ayo aphezulu engaphantsi. Ixabiso lezinto zeSmCo lelona libiza kakhulu, ke ngoko iSmCo icetyiswa kuphela xa ukusebenza kwayo yindawo enobushushu obuphezulu kuyinkxalabo.
 
Umazibuthe we-1.SmCo osisigxina unemveliso yamandla ombane kunye namandla aphezulu okunyanzela. Iipropathi zayo zibhetele kuneAlnico, umazibuthe osisigxina weferrite. Ubukhulu bayo. imveliso amandla ukuya ku 239kJ / m3 (30MGOe), nto leyo kathathu leyo AlNiCo8 umazibuthe esisigxina, amaxesha asibhozo ukuba ferrite umazibuthe esisigxina (Y40). Ke icandelo elisisigxina lemagnethi elenziwe ngezinto zeSmCo lincinci, lilula kwaye lizinzile kwipropathi. Isetyenziswa ngokubanzi kwi-electro acoustic kunye nezixhobo zonxibelelwano ngomatshini, iinjini zombane, imilinganiselo yeemitha, isikhonkwane esiphambili sokubukela ngombane, izixhobo zemicrowave, indlela yemagneti, inzwa kunye nezinye iindlela ezimileyo okanye ezinamandla.
 
2.Ixesha le-curie. of umazibuthe SmCo esisigxina liphezulu temp yayo. Umlingani. iphantsi. Ke ilungele ukusetyenziswa kuma-300, itempele ephezulu.
 
Umazibuthe weSmCo osisigxina uva kwaye uyabhabha. Ukuqina kwayo, amandla eqine kunye namandla okucinezela asezantsi. Ke ayisihambelanga sikhokelo.
 
Esona sithako siphambili sombane womazibuthe osisigxina yicobalt yentsimbi (CoY4%). Ixabiso layo liphezulu.


Inzuzo Yokukhuphisana:
Iimpawu Samarium ayibe Magnet

* Iimpawu eziphakamileyo kakhulu ezinokuzinza okuhle.
* Ukuxhathisa okuphezulu kubushushu obuphezulu, ubushushu beCurie besininzi ngaphezulu kwe-800 ?? * Wokugqaba nokumelana amandla, akukho ukutyabeka efunekayo ukuze ukhuseleko komhlaba.
