Halabuurka AlNiCo
Alnico magnetsWaa mid ka mid ah kuwii ugu horreeyay ee la sameeyay maaddada magnet joogto ah, waa daawaha ka kooban aluminium, nikkel, cobalt, birta iyo walxo kale oo bir raad raac ah. Maaddada magnet joogto ah ee Alnico ayaa si guul leh loo sameeyay 1930-meeyadii. Ka hor inta aan la abuurin qalabka magnetka joogtada ah ee naadirka ah ee 1960-meeyadii, aluminium-nickel-cobalt alloy ayaa had iyo jeer ahaa qalabka magnetka joogtada ah ee ugu xoogga badan, laakiin ay ugu wacan tahay ka kooban biraha istaraatiijiga ah ee cobalt iyo nikkel, taasoo keentay kharashyo badan, iyadoo ay soo ifbaxday ferrite magnet joogto ah iyo naadirka dhulka magnet joogto ah, aluminium-nickel-cobalt alaabta codsiyada badan si tartiib tartiib ah bedelay. Si kastaba ha ahaatee, qaar ka mid ah codsiyada heerkulka sare iyomagnet sareshuruudaha xasilloonida, magnet-ka ayaa weli ku jira meel aan la ruxin.
Habka wax soo saarka Alnico iyo astaanta
Alnico magnetsWaxay leeyihiin laba hab oo wax-shubista iyo sinterinta ah, habka wax-shubkana waxa loo habayn karaa cabbirro iyo qaabab kala duwan; Marka la barbardhigo habka wax shubidda, sheyga sinteedku wuxuu ku xaddidan yahay cabbir yar, xajmiga dulqaadka bannaan ee la soo saaro ayaa ka fiican kan kabka bannaan ee bannaan, hantida magnetic wax yar ayuu ka hooseeyaa alaabta kabka, laakiin mashiinnada waa ka fiican.
Habka wax-soo-saarka ee aluminium nikkel cobalt shubaya → dhalaalid → tuurista → daaweynta kulaylka → tijaabinta waxqabadka → mashiinka → kormeerka → baakadaha.
Aluminium nickel cobalt ah oo la isku qurxiyo waxaa soo saara birta budada ah, habka wax soo saarku waa dufan → samaynta budada → riixida → sintering → daaweynta kulaylka → tijaabinta waxqabadka → mashiinka → kormeerka → baakadaha.
Hal qayb oo ka mid ah AlNiCo
Cufnaanta qulqulka magnetic-ka ee alaabtani waa mid sare, ilaa 1.35T, laakiin isku-duubnidooda gudaha aad ayuu u hooseeyaa, badiyaa wax ka yar 160 kA/m, qalooca demagnetization waa isbeddel aan toos ahayn, iyo aluminium nickel cobalt magnet loop joogto ah kuma beegna oo leh qalooca demagnetization, markaa fiiro gaar ah waa in la siiyaa gaar ahaan marka la naqshadeynayo oo la soo saarayo wareegga magnetic ee qalab. Magnet-ka joogtada ahi waa in hore loo dejiyaa. Tusaale ahaan AlNiCo alloy dhexdhexaad ah oo anisotropic ah, ka kooban Alnico-6 waa 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, inta soo hartayna waa Fe. Alnico-6 waxa uu leeyahay BHmax oo ah 3.9 megagauss-osteds (MG·Oe), qasabka ah 780 oersted, kulaylka Curie ee 860 °C, iyo heerkulka ugu sarreeya ee hawlgalka ee 525 °C. Marka loo eego xoogga hoose ee Al-Ni-Co wax magnet joogto ah, waxaa si adag loo mamnuucay in lala xiriiro walxo ferromagnetic inta lagu jiro isticmaalka, si aysan u keenin demagnetization ama qalloocin maxalli ah oo aan laga laaban karin.qulqulka magneticqaybinta cufnaanta.
Intaa waxaa dheer, si loo xoojiyo iska caabinteeda demagnetization, dusha sare ee Alnickel-cobalt tiirka magnetka joogtada ah waxaa inta badan loogu talagalay tiirar dheer ama ulo dhaadheer, sababtoo ah walxaha magnetka joogtada ah ee alnickel-cobalt ayaa leh awood farsamo oo hooseeya, qallafsanaan sare iyo jajab, taasoo keentay ee machinability liidata, si aan loo qaabayn karaa sida qayb ka mid ah qaab-dhismeedka, oo kaliya qadar yar oo shiidi ama EDM waa la baaraandegi karaa, iyo foornada iyo farsamaynta kale ee farsamada ma noqon kartaa. loo isticmaalo. Hangzhou Magnet Power Technology Co., Ltd. waxay leedahay awoodda shiida saxda ah ee alaabtan, saxnaanta processing waxaa lagu xakameyn karaa gudaha +/- 0.005 mm, oo uu leeyahay wax soo saarka iyo processing awoodda wax soo saarka gaarka ah, haddii ay tahay alaabta caadiga ah ama alaabada gaarka ah ee qaabka gaarka ah, waxaan ku siin karnaa habka iyo barnaamijka ku habboon.
Goobaha codsiga ee Alnico
Aluminium-nickel-cobalt-ka-soo-saarka alaabada waxaa inta badan loo adeegsadaa cabbiraadda, magnet-ka qalabka, qaybaha baabuurta, maqal-dhamaadka sare, qalabka milatariga iyo hawada hawada iyo meelo kale. Sintered aluminium nickel cobalt waxay ku habboon tahay soosaarka adag, iftiinka, khafiifka ah, alaabta yaryar, inta badan loo isticmaalo isgaarsiinta elektiroonigga ah, koobabka magnetka joogtada ah, furayaasha magnetoelectric iyo dareemayaasha kala duwan ee alaabooyinka warshadaha iyo macaamiisha ayaa u baahan inay isticmaalaan magnets joogto ah oo xoog leh, sida matoorada. Qaadista gitaarka korontada, makarafoonada, codbixiyaasha dareemayaasha, tuubooyinka mowjadaha safarka, (cowmagnet) iyo wixii la mid ah. Dhammaantood waxay isticmaalaan aluminium-nickel-cobalt magnets. Laakiin hadda, alaabooyin badan ayaa isbeddelaya si ay u isticmaalaan magnets dhulka naadir ah, sababtoo ah maaddada noocan oo kale ah waxay siin kartaa Br xooggan iyo BHmax sare, taas oo u oggolaanaysa mugga alaabta yar.
