Emva Kwemiboniso: Indlela Ezenziwa Ngayo Iimagnethi ZeNeodymium Ezimile Ngo-U

Kwimizi-mveliso apho amandla emagnethi, ugxininiso lwesikhokelo, kunye noyilo oluncinci kungaxoxiswana ngalo,Iimagnethi ze-neodymium ezimile okwe-Uyima njeeqhawe elingadunyiswanga. Kodwa ezi magnethi zinamandla, ezimile ngendlela eyahlukileyo, zizalwe njani? Uhambo oluvela kumgubo oluhlaza ukuya kumsebenzi wemagnethi osebenza kakuhle luphawu lwesayensi yezinto, ubunjineli obugqithisileyo, kunye nolawulo lomgangatho olucokisekileyo. Masingene kumgangatho wefektri.

Izinto ezisetyenziswa gwenxa: Isiseko

Konke kuqala nge-"NdFeB" triad:

• I-Neodymium (Nd): Inkwenkwezi yezinto ezinqabileyo zomhlaba, evumela amandla angaphezulu angenakuthelekiswa nanto.
• Intsimbi (Fe): Umqolo wesakhiwo.
• I-Boron (B): Isiqinisi, esongeza amandla okusebenza (ukuxhathisa ukususwa kombane).

Ezi zinto ziyaxutywa, zinyibilikiswe, zize zipholiswe ngokukhawuleza zibe ziiflakes, emva koko zigaywe zibe yipowder encinci, enobukhulu be micron. Eyona nto ibalulekileyo kukuba, ipowder kufuneka ingabi naoksijini (icutshungulwe kwigesi/i-vacuum engasebenziyo) ukuthintela i-oxidation ephazamisa ukusebenza kwemagnethi.

Inqanaba 1: Ukucinezela – Ukubumba Ikamva

Umgubo ufakwa kwiimolds. Kwiimagnethi ezimile okwe-U, kukho iindlela ezimbini zokucinezela ezisetyenziswa kakhulu:

1. Ukucinezela kwe-Isostatic:
   • Umgubo ugqunywe kwisikhunta esiguquguqukayo.
   • Iphantsi koxinzelelo lwe-hydraulic oluphezulu kakhulu (10,000+ PSI) kuzo zonke iindlela.
   • Ivelisa iiblanks ezikufutshane ne-net ezinobunzima obufanayo kunye nokulungelelaniswa kwemagnethi.
2. Ukucinezela okunqamlezileyo:
   • Intsimi yamagnetic ilungelelanisa amasuntswanangexeshaukucinezela.
   • Kubalulekile ukuphucula imveliso yamandla emagnethi(BH)ubuninziecaleni kweepali ze-U.

Kutheni kubalulekile: Ulungelelwaniso lwamasuntswana lumisela amandla emagnethi—i-U-magnet engalungelelaniswanga kakuhle ilahlekelwa kukusebenza okungaphezulu kwama-30%.

Inqanaba lesi-2: Ukusila – "Umlilo oBonding"

Iindawo ezicinezelweyo "eziluhlaza" zingena kwiifutha ze-vacuum sintering:

• Ifudunyezwe ukuya kuthi ga kwi-≈1080°C (kufuphi nendawo yokunyibilika) kangangeeyure.
• Amasuntswana adibana abe yi-microstructure eqinileyo neqinileyo.
• Ukupholisa okucothayo kukwimo yekristale.

Umngeni: Ii-U-shapes zinobunzima bokugoba ngenxa yokusasazwa kobunzima obungalinganiyo. Uyilo lwe-fixture kunye ne-curves yobushushu echanekileyo zibalulekile ukugcina uzinzo olulinganayo.

Inqanaba lesi-3: Ukwenziwa kweMishini – Ukuchaneka kwiGophe ngalinye

I-NdFeB e-Sintered ibuthathaka (njenge-ceramic). Ukuyila i-U kufuna ubuchule bezixhobo zedayimani:

• Ukusila: Amavili agqunywe ngedayimani asika igophe langaphakathi kunye nemilenze yangaphandle ukuya kumlinganiselo we-±0.05 mm.
• I-Wire EDM: Kwiiprofayili ze-U ezintsonkothileyo, intambo etshajiweyo iyawutshisa umphunga wezinto ngokuchanekileyo kwe-micron.
• Ukuqhekeka: Zonke iikona zigudisiwe ukuze kuthintelwe ukuqhekeka kunye nokujikeleza kwemagnethi okuqinileyo.

Inyani eyonwabisayo: Inkunkuma yokugaya ye-NdFeB iyatsha kakhulu! Iinkqubo zokupholisa zithintela iintlantsi kwaye zibambe amasuntswana ukuze asetyenziswe kwakhona.

Inqanaba lesi-4: Ukugoba – Xa iiMagnets zidibana neOrigami

Indlela eyahlukileyo yeemagnethi ezinkulu ze-U:

1. Iibhloko ezizinxantathu ziyasilwa kwaye zigayiwe.
2. Ishushu ukuya kuthi ga kwi-≈200°C (ngaphantsi kobushushu beCurie).
3. Igoba nge-hydraulic ibe "U" ngokuchasene nokuchaneka.

Ubugcisa: Ukukhawuleza kakhulu = ukuqhekeka. Kubanda kakhulu = ukuqhekeka. Ubushushu, uxinzelelo, kunye nerediyasi yokugoba kufuneka zihambelane ukuze kuthintelwe ukuqhekeka okuncinci okwenza imagnethi ibe buthathaka.

Inqanaba lesi-5: Ukwaleka – Isikrweqe

I-NdFeB engenanto idla ngokukhawuleza. Ukwaleka akunakuxoxiswana ngako:

• Ukufakelwa nge-Electroplating: Iileya ezintathu ze-nickel-copper-nickel (Ni-Cu-Ni) zibonelela ngokumelana nokugqwala okuqinileyo.
• I-Epoxy/Parylene: Yenzelwe ukusetyenziswa kwezonyango/kwendalo apho ii-ion zesinyithi zingavumelekanga.
• Izinto ezikhethekileyo: Igolide (ye-elektroniki), iZinc (ixabiso layo liphantsi).

Umngeni we-U-Shape: Ukugquma i-tight inner curve ngokulinganayo kufuna i-barrel plating ekhethekileyo okanye iinkqubo ze-robotic spray.

Inqanaba lesi-6: Ukutsala umbane – "Ukuvuka"

Imagnethi ifumana amandla ayo okugqibela, ithintela umonakalo ngexesha lokuphathwa kwayo:

• Ibekwe phakathi kweekhoyili ezinkulu eziqhutywa yi-capacitor.
• Ixhomekeke kwi-pulsed field engaphezulu kwama-30,000 Oe (3 Tesla) kwii-milliseconds.
• Icala lentsimi libekwe ngokuthe nkqo kwisiseko sika-U, lilungelelanisa iipali ezikwiincam.

Ingcaciso ebalulekileyo: Iimagnethi ze-U zihlala zifuna imagnethi yeepole ezininzi (umz., iipole ezitshintshanayo ebusweni bangaphakathi) ukuze zisetyenziswe yi-sensor/motor.

Inqanaba lesi-7: Ulawulo loMgangatho – Ngaphaya kweeGauss Meters

Yonke i-U-magnet ivavanywa ngokungenalusini:

1. I-Gaussmeter/Fluxmeter: Ilinganisa intsimi yomphezulu kunye noxinano lwe-flux.
2. Umatshini wokulinganisa oQokelelweyo (i-CMM): Uqinisekisa ukuchaneka kobukhulu be-micron.
3. Uvavanyo lweTyuwa: Luqinisekisa ukuqina kwengubo (umz., ukumelana neeyure ezingama-48–500 nangaphezulu).
4. Uvavanyo lokuTsala: Kwimagnethi yokubamba, kuqinisekisa amandla okuncamathelisa.
5. Uhlalutyo lweDemagnetization Curve: Iqinisekisa (BH)max, Hci, HcJ.

Iziphene? Nokuba ukuphambuka kwe-2% kuthetha ukwaliwa. Ii-U-shapes zifuna ukugqibelela.

Kutheni i-U-Shape ifuna ubuchule obuphezulu bobugcisa

1. Uxinzelelo: Ukugoba kunye neekona ziyingozi yokuqhekeka.
2. Ukunyaniseka kwendlela yokujikeleza: Iimilo ezingalinganiyo zikhulisa iimpazamo zokulungelelanisa.
3. Ukufana kwengubo: Iigophe zangaphakathi zibamba amaqamza okanye amabala amancinci.
