Ukuqulunqwa kweSamarium Cobalt eziziimagnethi ezisisigxina
Imagnethi esisigxina yeSamarium cobalt yimagnethi yomhlaba enqabileyo, ikakhulu yenziwe nge-metal samarium (Sm), i-cobalt yensimbi (Co), ubhedu (Cu), intsimbi (Fe), i-zirconium (Zr) kunye nezinye izinto, ukusuka kwisakhiwo sahlulwe sibe yi-1 :5 uhlobo kunye no-2:17 uhlobo ezimbini, zeyesizukulwana sokuqala kunye nesizukulwana sesibini sezinto ezinqabileyo zomhlaba ezisisigxina zemagnethi. Imagnethi esisigxina yeSamarium cobalt ineempawu ezibalaseleyo zemagneti (i-remanence ephezulu, ukunyanzeliswa okuphezulu kunye nemveliso yamandla kamagnetic), iqondo lobushushu elisezantsi kakhulu, ubushushu benkonzo ephezulu kunye nokumelana nomhlwa okuqinileyo, yeyona nto ibalaseleyo yokumelana nobushushu bemagnethi esisigxina, isetyenziswa kakhulu kwizixhobo ze-microwave, i-electron. izixhobo ze-beam, amandla aphezulu / iimotor ezinesantya esiphezulu, izinzwa, izixhobo zemagneti kunye namanye amashishini.
Umsebenzi we-2:17 samarium-cobalt umazibuthe
Enye yezona magnethi zidumileyo ze-samarium-cobalt yimagnethi ye-2:17 samarium-cobalt, uthotho lweemagnethi ezaziwa ngepropathi yazo ephezulu yamagnetic, zibenza babe lukhetho lokuqala lwezicelo ezifuna amandla amakhulu kunye nozinzo.
Ukususela kwiimpawu zokusebenza, i-2: 17 samarium-cobalt imagnethi esisigxina inokwahlulwa ibe yinkqubo ephezulu yokusebenza, uchungechunge oluzinzileyo oluphezulu (i-coefficient ephantsi yobushushu) kunye nochungechunge lokumelana nobushushu obuphezulu. Indibaniselwano ekhethekileyo yoxinano lwamandla ombane aphezulu, uzinzo lobushushu kunye nokumelana nomhlwa kwenza imagnethi esisigxina yesamarium-cobalt ilungele usetyenziso olwahlukeneyo, kubandakanya iimotor zombane, izinzwa, udibaniso lwemagnethi kunye nezahluli zemagnethi.
Ubuninzi bemveliso yamandla kazibuthe kwibakala ngalinye phakathi kwe-20-35MGOe, kwaye ubushushu obuphezulu bokusebenza yi-500℃. Imagnethi esisigxina ye-Samarium-cobalt inodibaniso olukhethekileyo lobushushu obuphantsi kunye nokumelana kakuhle nokugqwala, ukuxinana kwamandla kamagnethi, ukuzinza kobushushu kunye nokumelana nomhlwa, okwenza imagnethi esisigxina yesamarium-cobalt ilungele uluhlu olubanzi lwezicelo, kubandakanya iimotor zombane, izinzwa, imagnethi. ukudibanisa kunye nezahluli zemagneti. Iimpawu zemagnethi zemagnethi zeNdfeb kumaqondo obushushu aphezulu zidlula imagnethi ye-NdFeb, ngoko ke zisetyenziswa ngokubanzi kwi-aerospace, amasimi omkhosi, iimotor zobushushu obuphezulu, izinzwa zeemoto, iidrive ezahlukeneyo zemagnethi, iimpompo zemagneti kunye nezixhobo ze-microwave. 2:17 uhloboiimagnethi zesamarium cobalt I-brittle kakhulu, akukho lula ukuyiqhuba kwiimilo eziyinkimbinkimbi okanye ngokukodwa amaphepha amancinci kunye namakhonkco amancinci, ukongeza, kulula ukubangela iikona ezincinci kwinkqubo yokuvelisa, ngokubanzi nje ukuba ayichaphazeli iipropati zemagnethi okanye imisebenzi, inokuthathwa njengeemveliso ezifanelekileyo.
Isishwankathelo, iimagnethi ezisisigxina zesamarium cobalt, ngakumbi uthotho lwamandla ombane aphezuluSm2Co17 iimagnethi, zixabiswa kakhulu ngenxa yezinto ezigqwesileyo zamagnetic kunye nokuzinza. Ukukwazi kwabo ukumelana namaqondo obushushu aphezulu kunye neemeko ezingqongileyo ezirhabaxa kubenza babe lolona khetho lokuqala lokufaka izicelo ngenkani kuwo wonke amashishini. Njengoko itekhnoloji iqhubeka nokuhambela phambili, imfuno yemagnethi esisigxina ye-samarium-cobalt kulindeleke ukuba ikhule, iqinise ngakumbi isikhundla sabo njengenxalenye ephambili yezicelo zale mihla zamashishini kunye nezorhwebo.
