Manika Zhou Magnet Power ya Vacuum Aluminium yatwikiriye Magnet
Ibisobanuro bigufi:
Vacuum aluminiyumu yatwikiriye Magnet Magnet, yakozwe kandi ikorwa na Hang Zhou Magnet Power, itanga imbaraga zidasanzwe kandi ziramba. Ubwubatsi bwayo budasanzwe bwemeza ko bushobora kwihanganira ibintu bisabwa cyane, bikabera igisubizo cyiza kubikorwa byinshi byinganda nubucuruzi.
●Magnette NdFeBByakoreshejwe Byinshi Kubintu Byinshi bya Magnetique. Nyamara, imbaraga za magnesi zirwanya ruswa zibuza gukomeza gukoreshwa mubucuruzi, kandi gutwikira hejuru birakenewe. Ibifuniko bikoreshwa cyane muri iki gihe birimo amashanyarazi ya Ni-shitingi, amashanyarazi ya Zn ashingiye, hamwe na electrophoreque cyangwa spray epoxy. Ariko hamwe niterambere ryiterambere ryikoranabuhanga, ibisabwa kugirango coatings ya NdFeB nayo iriyongera, kandi amashanyarazi asanzwe rimwe na rimwe ntashobora kuzuza ibisabwa. Igikoresho cya Al gishingiye kububiko ukoresheje tekinoroji yumubiri (PVD) ifite ibintu byiza biranga.
Technics Ubuhanga bwa PVD nko gusuka, gufata ion, hamwe no guhumeka bishobora guhumeka neza. Imbonerahamwe 1 irerekana amahame nibiranga kugereranya uburyo bwo gukwirakwiza amashanyarazi.
Imbonerahamwe 1 Kugereranya ibiranga uburyo bwo gukoresha amashanyarazi
Gusohora ni ibintu byo gukoresha ingufu zifite ingufu nyinshi kugirango bitere hejuru ikomeye, bitera atome na molekile hejuru yikibanza cyo guhanahana imbaraga za kinetic hamwe nuduce twinshi twinshi, bityo bikavamo hejuru. Yavumbuwe bwa mbere na Grove mu 1852. Ukurikije igihe cyayo cyiterambere, habayeho gusohora kwa kabiri, guterana kwa kaminuza, nibindi. Ariko, kubera ubushobozi buke bwo gusohora nizindi mpamvu, ntabwo yakoreshejwe cyane kugeza mu 1974 igihe Chapin yavumburaga magnetron iringaniye, bigatuma umuvuduko mwinshi nubushyuhe buke butera impamo, kandi tekinoroji ya magnetron yashoboye gutera imbere byihuse. Imashini ya Magnetron ni uburyo bwo gusohora butangiza amashanyarazi ya electronique mugihe cyo gusohora kugirango yongere igipimo cya ionisation kugera kuri 5% -6%. Igishushanyo mbonera cya magnetron iringaniye iragaragara mu gishushanyo 1.

Bitewe no kurwanya ruswa nziza, Al coating yabitswe na ion vapor deposition (IVD) yakoreshejwe na Boeing nk'igisimbuza amashanyarazi Cd. Iyo ikoreshejwe gucumura NdFeB, iba ifite ibyiza bikurikira:
1.High imbaraga zifatika.
Imbaraga zifatika za Al naNdFeBmuri rusange ≥ 25MPa, mugihe imbaraga zifatika za amashanyarazi asanzwe Ni na NdFeB zingana na 8-12MPa, naho imbaraga zifatika za Zn na NdFeB zifite amashanyarazi ni 6-10MPa. Iyi mikorere ituma Al / NdFeB ibereye porogaramu iyo ariyo yose isaba imbaraga zifatika. Nkuko bigaragara ku gishushanyo cya 2, nyuma yo guhinduranya inzinguzingo 10 zingaruka hagati ya (-196 ° C) na (200 ° C), imbaraga zifatika za Al coating zikomeza kuba nziza.

2. Shira muri kole.
Igifuniko cya Al gifite hydrophilicity kandi impande zifatika za kole ni nto, nta ngaruka zo kugwa. Igishushanyo cya 3 cyerekana 38mN yubuso bwamazi. Ikizamini cyamazi yakwirakwijwe rwose hejuru ya Al coating.
Igishushanyo 3. Ikizamini cya 38mN hejuru yubushyuhe
3.Imyuka ya magnetiki ya Al iri hasi cyane (ugereranije ni: 1.00) kandi ntabwo bizatera gukingira ibintu bya magneti.
Ibi ni ingenzi cyane mugukoresha amajwi mato mato mu murima wa 3C. Imikorere yo hejuru ni ngombwa cyane. Nkuko bigaragara ku gishushanyo cya 4, kuri D10 * 10 icyitegererezo cyinkingi, ingaruka za Al coating kuri magnetique ni nto cyane.
Igicapo 4 Impinduka mumiterere ya magnetiki ya NdFeB yacumuye nyuma yo gushira PVD Al igifuniko no gukwirakwiza amashanyarazi ya NiCuNi hejuru.
5.Uburyo bwo kubika tekinoroji ya PVD bwangiza ibidukikije rwose kandi ntakibazo gihumanya ibidukikije.
Ukurikije ibisabwa bifatika bikenewe, tekinoroji ya PVD irashobora kandi kubitsa abantu benshi, nka Al / Al2O3 multilayers ifite imbaraga zo kurwanya ruswa hamwe na Al / AlN ikoresheje ibikoresho byiza bya mashini. Nkuko bigaragara ku gishushanyo cya 5, imiterere yambukiranya ibice bya Al / Al2O3.
Igishushanyo 5 Igice cyambukiranya Al / Al2O3 multilyaers
Kugeza ubu, ibibazo nyamukuru bigabanya inganda za Al coatings kuri NdFeB ni:
(1) Impande esheshatu za magneti zabitswe kimwe. Ibisabwa mu kurinda magneti ni ukubika igifuniko gihwanye hejuru yinyuma ya magneti, bisaba gukemura uruziga rwibice bitatu bya rukuruzi mugutunganya ibyiciro kugirango harebwe niba ubwiza bwa coating;
(2) Igikorwa cyo kwambura ubusa. Mubikorwa binini byo gutunganya inganda, byanze bikunze ibicuruzwa bitujuje ibyangombwa bizagaragara. Niyo mpamvu, birakenewe kuvanaho Al itujuje ibyangombwa no kongera kuyirinda bitangiza imikorere ya magneti ya NdFeB;
(3) Ukurikije ibidukikije byihariye, magnet ya NdFeB yacumuye ifite amanota menshi. Niyo mpamvu, birakenewe kwiga uburyo bukwiye bwo kurinda amanota atandukanye;
(4) Gutezimbere ibikoresho byo gukora. Ibikorwa byo kubyaza umusaruro bigomba kwemeza neza umusaruro ushimishije, bisaba iterambere ryibikoresho bya PVD bikwiranye no kurinda magnet ya NdFeB kandi bifite umusaruro mwinshi;
(5) Kugabanya ikiguzi cy'umusaruro w'ikoranabuhanga wa PVD no kuzamura ubushobozi bwo guhangana ku isoko;
Nyuma yimyaka yubushakashatsi niterambere ryinganda. Ikoranabuhanga rya Hangzhou Magnet ryashoboye gutanga ibicuruzwa byinshi bya PVD Al byuzuye kubakiriya. Nkuko bigaragara ku mibare hepfo, amafoto yibicuruzwa bijyanye.
