Nkeji 1: Ịpị - Ịhazi Ọdịnihu

A na-etinye ntụ ntụ n'ime ihe ọkpụkpụ. Maka magnetik U-ụdị, ụzọ abụọ ịpị aka na-achịkwa:

1. Isostatic ịpị:
   • A na-etinye ntụ ntụ n'ime ihe na-agbanwe agbanwe.
   • Edoro ya na nrụgide hydraulic ultra-high (10,000+ PSI) site n'akụkụ niile.
   • Na-ewepụta oghere dị nso-ụgbụ a nwere njupụta otu yana nhazi ndọta.
2. Ntinye ntụgharị:

Nkeji 2: Sintering - The "Bonding Fire"

Akụkụ "acha akwụkwọ ndụ akwụkwọ ndụ" a na-etinye na-abanye n'ọkụ na-ekpo ọkụ:

• Na-ekpo ọkụ ruo ≈1080C (n'akụkụ ebe mgbaze) ruo awa.
• Ụmụ irighiri ihe na-abanye n'ime nnukwu microstructure siri ike.
• Mkpọchi na-adị nwayọọ nwayọọ na nhazi kristal.

Ihe ịma aka ahụ: U-ụdị na-adị mfe ịlụ ọgụ n'ihi nkesa na-enweghị isi. Nhazi nrụnye na oke okpomọkụ dị oke mkpa iji kwado nkwụsi ike nke akụkụ.

Nkeji 3: Nrụpụta - nkenke na akụkụ ọ bụla

Sintered NdFeB na-akụkụ (dị ka seramiiki). Ịmezi U chọrọ njikwa ngwa diamond:

• Na-egweri: wiil ndị nwere ola diamond na-egbutu akụkụ ime na n'elu ụkwụ ruo na nnabata nke ±0.05 mm.
• Waya EDM: Maka profaịlụ U-mgbagwoju anya, waya ebubo na-eme ka ihe dị mma na-ekpo ọkụ.
• Chamfering: A na-eme ka akụkụ niile dị nro iji gbochie chipping na itinye uche ndọta.

Eziokwu na-atọ ụtọ: NdFeB egweri sludge bụ nke ukwuu ire ọkụ! Sistemụ oyi na-atụ na-egbochi ọkụ ọkụ na ijide ụmụ irighiri ihe maka imegharị ihe.

Nkeji 4: Na-ehulata - Mgbe Igwe Ọdụdọ Zute Origami

Ụzọ ọzọ maka nnukwu U-magnets:

1. A na-agbaji ihe mgbochi akụkụ anọ na ala.
2. Na-ekpo ọkụ ruo ≈200C (n'okpuru Curie okpomọkụ).
3. Ekwenyere hydraulically n'ime "U" megide nkenke na-anwụ.

The Art: Oke ngwa ngwa = mgbawa. Oyi juru oke = mgbaji. Okpomọkụ, nrụgide, na radius ehulata ga-adakọrịrị iji zere obere mgbaji na-eme ka magnetik ghara ịdị ike.

Nkeji 5: mkpuchi - Ihe agha

Bare NdFeB na-emebi ngwa ngwa. Ihe mkpuchi mkpuchi enweghị nkwekọrịta:

• Electroplating: Nickel-ọla kọpa-nickel (Ni-Cu-Ni) okpukpu atọ na-enye nguzogide corrosion siri ike.
• Epoxy/Parylene: Maka ngwa ahụike/gburugburu ebe ion igwe amachibidoro.
• Ọpụrụiche: Gold (eletrọnịkị), Zinc (dị ọnụ ahịa).

Ihe ịma aka U-Ọdịbe: Ikpuchi akụkụ dị n'ime nke siri ike na-achọkwa akwa mkpuchi gbọmgbọm pụrụ iche ma ọ bụ sistemu ịgba ígwè.

Nkeji 6: Magnetizing - "Mkpalite"

Igwe ndọta ahụ na-enweta ike ya n'ikpeazụ, na-ezere mmebi n'oge njikwa:

• Etinyere n'etiti nnukwu eriri igwe na-ebugharị capacitor.
• Edere ya n'ọhịa pulsed> 30,000 Oe (3 Tesla) maka milliseconds.
• A na-edobe ntụzịaka ubi ka ọ dị na ntọala U, na-edozi okporo osisi n'ọnụ ọnụ.

Isi nuanceU-magnets na-achọkarị magnetization ọtụtụ pole (dịka ọmụmaatụ, okporo osisi ndị ọzọ n'ofe ihu dị n'ime) maka ojiji sensọ/moto.

Nkeji 7: Njikwa Ogo - Na-agafe Mita Gauss

U-magnet ọ bụla na-enweta ule enweghị obi ebere:

1. Gaussmeter/Fluxmeter: Na-atụ mbara ala & njupụta njupụta.
2. Igwe eji ahazi nhazi (CMM): Na-enyocha izi ezi nha-ọkwa micron.
3. Nnwale ịgbasa nnu: Na-akwado ịdịte aka mkpuchi (dịka nguzogide awa 48–500+).
4. Nnwale sere: Maka ijide ndọta, na-akwado ike nrapado.
5. Analysis Curve Demagnetization: Na-akwado (BH) max, Hci, HcJ.

Ọdịda? Ọbụna 2% deviation pụtara ịjụ. U-ụdị chọrọ izu oke.

Kedu ihe kpatara U-Shape ji achọ nka nka

1. Ntụkwasị obi mgbakasị: Ehulata na nkuku bụ ihe egwu mgbaji.
2. Iguzosi ike n'ezi ihe n'ụzọ Flux: Ụdị asymmetric na-ebuli mperi nhazi.
3. Ịdị n'otu mkpuchi mkpuchi: akụkụ nke ime na-ejide ọnyà ma ọ bụ ntụpọ dị mkpa.
