Ngasemva kweSigcawu: Indlela oMilise ngayo iiMagnet zeNeodymium zenziwa

Kumashishini apho amandla emagnethi, ujoliso olukhomba indlela, kunye noyilo olubambeneyo lungenakuxoxisana,Imagnethi ye-neodymium emile okwe-Uyimani njengamagorha angaziwayo. Kodwa zizalwa njani ezi magnethi zinamandla, zimile ngendlela ekhethekileyo? Uhambo olusuka kumgubo okrwada ukuya kwihashe elisebenza ngamandlakazibuthe ngumsebenzi wesayensi yezinto, ubunjineli obugqithisileyo, kunye nolawulo olucokisekileyo lomgangatho. Masingene ngaphakathi kumgangatho wefektri.

IMathiriyeli ekrwada: Isiseko

Konke kuqala nge "NdFeB" triad:

• I-Neodymium (Nd): Inkwenkwezi yezinto ezinqabileyo zomhlaba, eyenza amandla omagnetic angenakuthelekiswa nanto.
• Intsimbi (Fe): Umqolo wesakhiwo.
• I-Boron (B): I-stabilizer, ukuqinisa ukunyanzeliswa (ukuchasana nokukhutshwa kweemagneti).

Ezi zinto zixutywe, zinyibilike, kwaye zipholile ngokukhawuleza kwiiflakes, emva koko zigaywe zibe ngumgubo ocolekileyo, ubungakanani bemicron. Okubaluleke kakhulu, i-powder kufuneka ingabi ne-oxygen (iqhutywe kwi-inert gas / vacuum) ukukhusela i-oxidation ekhubaza ukusebenza kwamagnetic.

Inqanaba 1: Ukucinezela - Ukubumba iKamva

Umgubo ulayishwa kwi-molds. Kwiimagnethi ezimilise u-U, iindlela ezimbini zokucinezela zilawula:

1. I-Isostatic Pressing:
   • Umgubo ufakwe kwi-mold eguquguqukayo.
   • Iphantsi koxinzelelo lwe-ultra-high hydraulic (10,000+ PSI) ukusuka macala onke.
   • Ivelisa izikhewu ezikufutshane-netha ezinobunzima obufanayo kunye nokulungelelaniswa kwemagnethi.
2. Ukucinezela ngokuNqambuda:
   • Umhlaba wemagnethi ulungelelanisa amasuntswanangexeshaucinezela.
   • Okubalulekileyo ekwandiseni imveliso yamandla emagnethi(BH)ubuninziecaleni kweepali ze-U.

Kutheni kubalulekile nje?: Ulungelelwaniso lwesuntswana lumisela amandla ahamba umazibuthe-i-U-magnet engalungiswanga kakuhle ilahlekelwa ngu> 30%.

Inqanaba lesi-2: Sintering- "Umlilo oBonding"

Amalungu acinezelweyo "luhlaza" angena kwiifurnas zevacuum sintering:

• Ifudunyezwe kwi-≈1080 ° C (kufuphi nendawo yokunyibilika) iiyure.
• Amalungu axubana abe ngqindilili, ulwakhiwo oluluqilima.
• Ukupholisa okucothayo kwizitshixo kwisakhiwo sekristale.

Ucelomngeni: Iimilo ze-U ziqhelene nokungqubana ngenxa yosasazo oluninzi olungalinganiyo. Uyilo lwe-Fixture kunye nee-curves ezichanekileyo zokushisa zibalulekile ukugcina uzinzo lwe-dimensional.

Inqanaba lesi-3: UMatshini – Ukuchaneka kuwo onke amagophe

I-Sintered NdFeB inobuqhophololo (njenge-ceramic). Ukubumba i-U kufuna ubuchule besixhobo sedayimani:

• Ukugaya: Amavili anedayimani aqatywe ngedayimani anqumle igophe langaphakathi kunye nemilenze yangaphandle ukuya kukunyamezela kwe-± 0.05 mm.
• I-EDM yocingo: Kwiiprofayili ze-U eziyinkimbinkimbi, ucingo oluhlawulisiweyo lufunxa izinto ngokuchaneka kwe-micron.
• I-Chamfering: Yonke imiphetho igudiswa ukunqanda ukutshiphuza kunye nokugxila kwi-magnetic flux.

Inyani eyonwabileyo: I-NdFeB yokusila i-sludge iyatsha kakhulu! Iinkqubo zokupholisa zithintela iintlantsi kwaye zibambe amasuntswana ukuze ziphinde zisetyenziswe.

Inqanaba lesi-4: Ukugoba – Xa iimagnethi zidibana neOrigami

Enye indlela yee-U-magnets ezinkulu:

1. Iibhloko ezixande ziyacolwa kwaye ziphantsi.
2. Ukufudumala ukuya ku-≈200 ° C (ngaphantsi kweqondo lokushisa kweCurie).
3. Ukugotywa kwamanzi kwi "U" ngokuchasene nokuchaneka kuyafa.

Ubugcisa: Ngokukhawuleza kakhulu = iintanda. Kubanda kakhulu = ukwaphuka. Iqondo lobushushu, uxinzelelo, kunye neradiyasi egobileyo kufuneka ihambelane ukunqanda iifractures ezincinci eziwenza buthathaka umazibuthe.

Inqanaba lesi-5: Ukwambathisa-Isikrweqe

I-Bare NdFeB idleka ngokukhawuleza. Ukwaleka akuxoxiswana:

• I-Electroplating: I-Nickel-copper-nickel (Ni-Cu-Ni) i-triple layers inika ukuxhathisa okuqinileyo kwe-corrosion.
• I-Epoxy/Parylene: Kwizicelo zonyango/zendalo apho ii-ion zetsimbi zingavumelekanga.
• I-Specialty: Igolide (i-electronics), i-Zinc (ixabiso elisebenzayo).

Umngeni we-U-Shape: Ukugquma igophe langaphakathi eliqinileyo ngokulinganayo kufuna ipleyiti ekhethekileyo yomphanda okanye iinkqubo zokutshiza ngerobhothi.

Inqanaba lesi-6: Ukwenza imagnethi - "Ukuvuka"

Imagnethi ifumana amandla ayo okokugqibela, inqanda umonakalo ngexesha lokuphatha:

• Ibekwe phakathi kweekhoyili ezinkulu eziqhutywa yi-capacitor.
• Ixhomekeke kwintsimi ye-pulsed> 30,000 Oe (3 Tesla) kwii-milliseconds.
• Ulwalathiso lwentsimi lubekwe ngokuthe ngqo kwisiseko se-U, iipali zokulungelelanisa kwiingcebiso.

I-nuance engundoqo: Iimagnethi ze-U zihlala zifuna i-multi-pole magnetization (umzekelo, iipali ezitshintshanayo kubuso bangaphakathi) kusetyenziso lwesivamvo/imoto.

Inqanaba lesi-7: Ulawulo loMgangatho-Ngaphaya kweGauss Meters

Yonke i-U-magnet ivavanywa ngokungenalusini:

1. I-Gaussmeter/Fluxmeter: Ilinganisa ibala lomphezulu kunye noxinaniso lokuhamba.
2. Ukulungelelanisa uMshini wokuMeta (CMM): Uqinisekisa ukuchaneka komgangatho we-micron-dimensional.
3. Uvavanyo lweSitshizi seTyuwa: Ukuqinisekisa ukuqina kokugquma (umzekelo, ukuxhathisa kweeyure ezingama-48–500+).
4. Tsala iimvavanyo: Ukubamba iimagnethi, iqinisekisa amandla ancamathelayo.
5. I-Demagnetization Curve Analysis: Iqinisekisa (BH) max, Hci, HcJ.

Iziphene? Nokuba ukuphambuka kwe-2% kuthetha ukwaliwa. Iimilo zika-U zifuna imfezeko.

Kutheni i-U-Shape ifuna ubuchwephesha bePremium

1. Ukugxininiswa koxinzelelo: Ukugoba kunye neekona yingozi yokuphuka.
2. I-Flux Path Integrity: Iimilo ze-asymmetric zikhulisa iimpazamo zokulungelelanisa.
3. I-Coating Uniformity: Iigophe zangaphakathi zibamba amaqamza okanye amabala amancinci.

"Ukwenza i-U-magnet ayisiyonto nje yokubumba izinto-yintoukulungelelanisaphysics."

Isiphelo: Apho Ubunjineli budibana khona noBugcisa

Ngexesha elizayo xa ubona umazibuthe omile okwe-neodymium ebambelela kwinjini enesantya esiphezulu, icoca iintsimbi ezisetyenzisiweyo, okanye ivumela impumelelo yezonyango, khumbula: igophe layo elihle lifihla isaga yokulungelelaniswa kweathom, ubushushu obugqithisileyo, ukuchaneka kwedayimani, kunye nokuqinisekiswa okungapheliyo. Oku ayikokwenza nje kuphela-luloyiso oluzolileyo lwenzululwazi yezixhobo etyhala imida yeshishini.

Unomdla kwiimagnethi ezimilise u-U?Yabelana ngeespekthi zakho - siza kukuzulela umeyi wokwenza.
