Ka morao ho Lits'oants'o: Kamoo U Sebelitseng Kateng Limanete tsa Neodymium

Liindastering tseo ho tsona matla a makenete, tsepamiso ea tataiso, le moralo o kopaneng li ke keng tsa buisanoa,Limanete tsa neodymium tse bōpehileng joaloka Uema joalo ka bahale ba sa bonoeng. Empa limakete tsee tse matla, tse nang le sebōpeho se ikhethang li tsoaloa joang? Leeto la ho tloha phofo e tala ho ea ho pere ea makenete e sebetsang hantle haholo ke ts'ebetso ea mahlale a thepa, boenjiniere bo feteletseng, le taolo e hlokolosi ea boleng. Ha re kene ka hare ho mokato oa feme.

Lisebelisoa tse tala: Motheo

Tsohle li qala ka "NdFeB" triad:

• Neodymium (Nd): Naleli ea lintho tse sa tloaelehang tsa lefatše, e nolofalletsang matla a khoheli a ke keng a lekanngoa.
• Tšepe (Fe): Mokokotlo wa sebopeho.
• Boron (B): The stabilizer, e matlafatsang coercivity (ho hanyetsa demagnetization).

Lintho tsena lia qhibiliha, lia qhibiliha, 'me ka potlako li pholile hore e be li-flakes, ebe li siloa ka phofo e ntle, e boholo ba micron. Habohlokoa, phofo e tlameha ho se be le oksijene (e sebetsoa ka khase ea inert / vacuum) ho thibela oxidation e holofatsang ts'ebetso ea makenete.

Mothati oa 1: Ho Tobetsa - Ho Bopa Bokamoso

Phofo e kenngoa ka har'a hlobo. Bakeng sa limakete tse nang le sebopeho sa U, ho na le mekhoa e 'meli ea khatiso:

1. Isostatic Pressing:
   • Phofo e kenngoe ka hlobo e tenyetsehang.
   • E tlas'a khatello e phahameng ea hydraulic (10,000+ PSI) ho tsoa mahlakoreng 'ohle.
   • E hlahisa likheo tsa sebopeho se haufi-ufi tse nang le tekano e ts'oanang le ho tsamaisana ha makenete.
2. Transverse Pressing:
   • Matla a makenete a tsamaisana le likaroloananakongho hatella.
   • E bohlokoa bakeng sa ho eketsa sehlahisoa sa matla a makenete(BH)maxhaufi le lipalo tsa U.

Hobaneng ho le bohlokoa: Ho tsamaisana ha likaroloana ho etsa qeto ea hore na matla a makenete a hokae - U-magnet e sa nepahalang e lahleheloa ke> 30% e sebetsang hantle.

Mothati oa 2: Sintering - The "Bonding Fire"

Likarolo tse hatisitsoeng tse "tala" li kenya libopi tsa vacuum sintering:

• E futhumetse ho ≈1080°C (haufi le sebaka se qhibilihang) ka lihora tse ngata.
• Likaroloana li kopana ka har'a "microstructure" e teteaneng, e tiileng.
• Liloko tse fokolang tse pholileng ka har'a sebopeho sa kristale.

Phephetso: Libopeho tsa U li tloaetse ho soahlamana ka lebaka la ho se lekane ka bongata. Moralo oa thepa le li-curve tse nepahetseng tsa mocheso li bohlokoa ho boloka botsitso ba sebopeho.

Mothati oa 3: Machining - Precision in Eng le E 'ngoe Curve

Sintered NdFeB e brittle (joaloka ceramic). Ho theha U ho hloka bokhoni ba sesebelisoa sa taemane:

• Ho sila: Mabili a koahetsoeng ka daemane a seha mothipa o ka hare le maoto a ka ntle ho fihlela boima ba ± 0.05 mm.
• Wire EDM: Bakeng sa li-U-profiles tse rarahaneng, terata e qosoang e etsa mouoane oa lintho tse bonahalang ka ho nepahala ha micron.
• Chamfering: Mathoko ohle a boreleli ho thibela ho phunya le ho tsepamisa mohopolo oa matla a khoheli.

'Nete e monate: NdFeB sila seretse se tukang haholo! Lisebelisoa tse futhumatsang li thibela litlhase le ho hapa likaroloana bakeng sa ho sebelisoa hape.

Mothati oa 4: Ho Koba - Ha Magnets a Kopana le Origami

Tsela e 'ngoe ea li-U-magnets tse kholo:

1. Li-blocks tse khutlonnetsepa lia silafatsoa le ho siloa fatše.
2. E futhumetse ho ≈200 ° C (ka tlase ho mocheso oa Curie).
3. Hydraulically e kobehile "U" khahlanong le ho nepahala e shoa.

The Art: Ka potlako haholo = mapetsong. Ho bata haholo = ho robeha. Thempereichara, khatello, le radius e kobehileng li tlameha ho lumellana ho qoba maqheka a manyenyane a fokolisang makenete.

Mothati oa 5: Ho roala - The Armor

Bare NdFeB e senya ka potlako. Ho roala ho ke ke ha buisanoa:

• Electroplating: Nickel-copper-nickel (Ni-Cu-Ni) likarolo tse tharo li fana ka khanyetso e matla ea kutu.
• Epoxy/Parylene: Bakeng sa lits'ebetso tsa bongaka / tsa tikoloho moo li-ion tsa tšepe li thibetsoeng.
• Tse khethehileng: Khauta (ea elektroniki), Zinc (e sa sebetseng hantle).

Phephetso ea U-Shape: Ho koahela lekhalo le ka hare le tiileng ka ho lekana ho hloka mokhoa o khethehileng oa ho roala libarele kapa li-spray tsa robotic.
