I-Hang Zhou Magnet Power's Vacuum yeAluminiyam efakwe iMagnet
Inkcazelo emfutshane:
I-aluminiyam egqunywe ngemagnethi umazibuthe, eyilwe yaza yenziwa yiHang Zhou Magnet Power, inika amandla amangalisayo kunye nokuqina. Ukwakhiwa kwayo okuyingqayizivele kuqinisekisa ukuba kunokumelana neemeko ezinzima kakhulu, okwenza kube sisisombululo esifanelekileyo kuluhlu olubanzi lwezicelo zoshishino kunye nezorhwebo.
●Sintered NdFeB umazibuthezisetyenziswe ngokubanzi kwiimpawu zazo ezimangalisayo zemagneti. Nangona kunjalo, ukunganyangeki komhlwa kweemagnethi kuthintela ukusetyenziswa kwabo ngokuqhubekayo kwizicelo zorhwebo, kunye nokwaleka komphezulu kuyafuneka. Iingubo ezisetyenziswa ngokubanzi okwangoku ziquka i-electroplating Ni-based coatings, i-electroplating Zn-based coatings, kunye ne-electrophoretic okanye i-spray epoxy coatings. Kodwa ngenkqubela phambili eqhubekayo yetekhnoloji, iimfuno zokugquma kwe-NdFeB nazo ziyanda, kwaye iileya ze-electroplating eziqhelekileyo ngamanye amaxesha azikwazi ukuhlangabezana neemfuno. Itekhnoloji ye-Al esekwe kusetyenziswa itekhnoloji yokubeka umphunga (PVD) ineempawu ezibalaseleyo.
● Ubuchule bePVD obunjengokutshiza, i-ion plating, kunye ne-evaporation plating zonke zinokufumana izinto ezikhuselayo. Itheyibhile 1 idwelisa imigaqo kunye neempawu zokuthelekisa iindlela ze-electroplating kunye ne-sputtering.

I-Sputtering yinto yokusebenzisa amasuntswana anamandla aphezulu ukubhobhoza indawo eqinileyo, ebangela iiathomu kunye neeathomu ezikumphezulu oqinileyo ukutshintshiselana ngamandla e-kinetic ngala masuntswana anamandla aphezulu, ngaloo ndlela atshiza aphume kumphezulu oqinileyo. Yafunyanwa okokuqala nguGrove ngo-1852. Ngokwexesha layo lophuhliso, kuye kwakho ukutshiza kwesibini, ukutshiza kwenqanaba eliphezulu, njalo njalo. Nangona kunjalo, ngenxa yokusebenza kakuhle kwe-sputtering ephantsi kunye nezinye izizathu, ayizange isetyenziswe ngokubanzi kude kube ngowe-1974 xa iChapin yenza i-balanced magnetron sputtering, isenza isantya esiphezulu kunye nobushushu obuphantsi bube yinyani, kwaye iteknoloji ye-magnetron sputtering yakwazi ukukhula ngokukhawuleza. I-Magnetron sputtering yindlela yokutshiza eyazisa imimandla ye-electromagnetic ngexesha lenkqubo yokutshiza ukunyusa izinga le-ionization ukuya kwi-5% -6%. Umzobo weskimu we-balanced magnetron sputtering uboniswe kuMfanekiso 1.

Ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, i-Al coating efakwe yi-ion vapor deposition (IVD) isetyenziswe yi-Boeing njengendawo ye-electroplating Cd. Xa isetyenziselwa i-sintered NdFeB, ikakhulu inezi zibonelelo zilandelayo:
1.High amandla okuncamathelisa.
Amandla ancamathelayo e-Al kunyeNdFeBngokubanzi ≥ 25MPa, lo gama amandla okuncamathelisa eqhelekileyo electroplated Ni kunye NdFeB malunga 8-12MPa, kunye namandla okuncamathelisa electroplated Zn kunye NdFeB malunga 6-10MPa. Olu phawu lwenza i-Al/NdFeB ilungele nasiphi na isicelo esifuna amandla ancamatheleyo aphezulu. Njengoko kubonisiwe kwi-Figure 2, emva kokutshintshana imijikelo ye-10 yempembelelo phakathi (-196 ° C) kunye (200 ° C), amandla okunamathela kwi-Al coating ahlala ebalaseleyo.

2. Gxuma kwiglue.
I-Al coating ine-hydrophilicity kunye ne-angle yoqhagamshelwano yeglue encinci, ngaphandle komngcipheko wokuwa. Umfanekiso wesi-3 ubonisa i-38mN yolwelo loxinzelelo lomphezulu. Ulwelo lovavanyo lusasazeke ngokupheleleyo kumphezulu we-Al coating.
Umzobo 3. uvavanyo lwe-38mN yoxinzelelo lwangaphandle
I-3.I-magnetic permeability ye-Al iphantsi kakhulu (i-relative permeability: 1.00) kwaye ayiyi kubangela ukukhuselwa kweepropati zemagneti.
Oku kubaluleke kakhulu ekusetyenzisweni kweemagnethi ezincinci kwintsimi ye-3C. Ukusebenza komphezulu kubaluleke kakhulu. Njengoko kubonisiwe kuMfanekiso 4, kwikholamu yesampula ye-D10 * 10, impembelelo ye-Al yokwambathisa kwiipropati zamagnetic incinci kakhulu.
Umzobo we-4 Utshintsho kwiipropathi zamagnetic ze-NdFeB ye-sintered emva kokubeka i-PVD Al yokugquma kunye ne-electroplating ye-NiCuNi yokugqoka phezu komhlaba.
5.Inkqubo yokubeka iteknoloji yePVD ihambelana ngokupheleleyo nokusingqongileyo kwaye akukho ngxaki yongcoliseko lwendalo esingqongileyo.
Ngokweemfuno ezisebenzayo, itekhnoloji ye-PVD inokufaka i-multilayers, njenge-Al/Al2O3 i-multilayers enokumelana nokugqwesa okugqwesileyo kunye neengubo ze-Al/AlN ezineempawu ezibalaseleyo zoomatshini. Njengoko kuboniswe kwi-Figure 5, i-cross-sectional structure ye-Al/Al2O3 yokwambathisa i-multilayer.

Okwangoku, ezona ngxaki ziphambili zithintela ukwenziwa kwemveliso ye-Al coatings kwi-NdFeB zezi:
(1) Amacala amathandathu umazibuthe abekwe ngendlela efanayo. Imfuneko yokhuseleko umazibuthe kukufaka isambatho esilinganayo kumphezulu wangaphandle umazibuthe, efuna ukusonjululwa komjikelezo-ntathu wemagnethi kwi-batch processing ukuqinisekisa ukuhambelana komgangatho wokwambathisa;
(2) Inkqubo yokuqhawula i-al-coating. Kwinkqubo yokuveliswa kwamashishini amakhulu, akunakuphepheka ukuba iimveliso ezingafanelekanga ziya kuvela. Ngoko ke, kuyimfuneko ukususa i-Al-coating engafanelekanga kwaye uyikhusele kwakhona ngaphandle kokonakalisa ukusebenza kweemagnethi ze-NdFeB;
(3) Ngokwemeko ethile yesicelo, iimagnethi ze-NdFeB ezine-sintered zinamabanga amaninzi kunye neemilo. Ke ngoko, kuyafuneka ukufunda iindlela ezifanelekileyo zokukhusela amabakala ahlukeneyo kunye neemilo;
(4) Ukuphuhliswa kwezixhobo zokuvelisa. Inkqubo yokuvelisa idinga ukuqinisekisa ukusebenza kakuhle kwemveliso, efuna ukuphuhliswa kwezixhobo zePVD ezifanelekileyo kwiNdFeB yokukhusela imagnethi kunye nokusebenza kakuhle kwemveliso;
(5) Ukunciphisa iindleko zokuvelisa iteknoloji yePVD kunye nokuphucula ukukhuphisana kwemarike;
Emva kweminyaka yophando kunye nophuhliso lwamashishini. I-Hangzhou Magnet Power Technology iye yakwazi ukubonelela ngeemveliso ezininzi zePVD Al ezifakwe kubathengi. Njengoko kuboniswe amanani angezantsi, iifoto ezifanelekileyo zemveliso.
