Ucingo lweKovariyi-wire ye-alloy ekhethekile enwebeka kancane, eyaziwa kabanzi ngezakhiwo zayo ezihlukile zokufanisa ukushisa.

Idlala indima ebalulekile ezimbonini ezinembe kakhulu njenge-elekthronikhi, izindiza, kanye nemishini yezokwelapha. Lo mhlahlandlela uphendula umbuzo oyinhloko wokuthi iyini intambo yeKovar futhi uchaza ukusetshenziswa kwayo okuyinhloko, kanye nezixazululo zethu zentambo yeKovar ezisezingeni eliphezulu.

1. Iyini i-Kovar Wire?

1.1 Incazelo Eyinhloko

Intambo yeKovar iyintambo ye-iron-nickel-cobalt alloy encibilikisiwe nge-vacuum, eyenzelwe ukulawula ukunwetshwa kokushisa okunembile.

Inzuzo yayo enkulu ukufanisa i-coefficient yokwandisa ukushisa kwengilazi ye-borosilicate kanye ne-ceramics, okuvumela ukuvalwa kwe-hermetic okungenamthungo.

1.2 Ukwakheka Kwamakhemikhali Okujwayelekile

Ucingo lweKovar lunokwakheka okulawulwa ngokuqinile ukuqinisekisa ukusebenza okuzinzile:

- Insimbi (Fe): 53-54% (ibhalansi)

- I-Nickel (Ni): 28.5-29.5%

- I-Cobalt (e-Co): 16.8-17.8%

Izakhi zokulandelela (i-Mn, i-Si, i-C) zikhawulelwe ngokuqinile ngaphakathi kwe-0.5% max ngayinye.

1.3 Izindinganiso Ezibalulekile Nezincazelo

Ihambisana nezindinganiso zomhlaba wonke ukuqinisekisa ukuvumelana kuzo zonke izinhlelo zokusebenza.

- I-ASTM F15 (izinga eliyinhloko lemikhiqizo ye-Kovar alloy)

- UNS K94610, Werkstoff Nr. 1.3981 (izimpawu zomhlaba jikelele)

Eyaziwa nangokuthi i-4J29 ezindinganisweni zaseShayina, ingashintshaniswa ne-Nilo-K kwezinye izindawo.

2. Izici Eziyinhloko Zocingo LweKovar

2.1 Ukwanda Kokushisa Okuphansi Nokuzinza

I-coefficient yayo yokwandisa ukushisa (4.6-5.2×10⁻⁶/℃, 20-400℃) ifanelana kahle nengilazi ye-borosilicate.

Lokhu kuqeda imifantu yokucindezeleka ngesikhathi sokushisa nokupholisa, okuqinisekisa ukuvalwa okuthembekile.

2.2 Ukucutshungulwa Okuhle Kakhulu

Inamandla okuguquguquka futhi ingadonswa ezintanjeni ezincane, igotshwe, futhi ihlanganiswe kalula.

Ifanele ukudweba okubandayo, ukunyathela, kanye nezindlela ezahlukene zokushisela (i-argon arc, ukushisela nge-laser).

2.3 Izinga Lokushisa Eliphezulu Nokuzinza Okungangenisi Igazi

Igcina ukusebenza okuzinzile emazingeni okushisa afinyelela ku-450℃, kanye nephuzu lokuncibilika elingu-1450℃.

Yakha izivalo ezingangeni moya ngengilazi/izitsha zobumba, ezibaluleke kakhulu ekusetshenzisweni kwe-vacuum kanye nokuthembeka okuphezulu.

3. Izintambo ze-Kovar vs. Izintambo ze-Alloy ezifanayo: Ithebula Lokuqhathanisa

Ithebula elingezansi liqokomisa izinzuzo eziyingqayizivele ze-Kovar wire kunezintambo ze-constantan neze-cupro nickel:

4. Isetshenziswa Kanjani Intambo yeKovar? Izimo Zokusebenza Eziyinhloko

4.1 Ukupakishwa Kwe-elekthronikhi Ne-semiconductor

Isetshenziswa njengezintambo zomthofu zamapayipi e-vacuum, ama-transistors, ama-diode, kanye namasekethe ahlanganisiwe.

Ivumela ukuvalwa kwe-hermetic nge-insulators yeglasi, ivikela izingxenye zangaphakathi emswakama nasekungcoleni.

4.2 Izindiza kanye Nezindiza

Kusetshenziswa ezingxenyeni ze-elekthronikhi zezindiza kanye namadivayisi okuxhumana ngesathelayithi.

Ukuqina kwayo kokushisa kumelana nokushintshashintsha okukhulu kwezinga lokushisa ezindaweni zezindiza.

4.3 Imishini Yezokwelapha

Kusetshenziswa ezinzwa zezokwelapha, imishini yokuxilonga, kanye nezixhumi ze-hermetic.

Ihlangabezana nezidingo eziqinile zokuhambisana kwezinto eziphilayo kanye nokuthembeka kwezicelo zezokwelapha.

4.4 Amadivayisi Optical & Vacuum

Kusetshenziswa ezivalweni zengilazi ezishintsha zibe yinsimbi zemicu yokukhanya, amashubhu e-microwave, kanye nemishini ye-X-ray.

Iqinisekisa ukungabi nomoya kanye nokuhambisana nokushisa kwezinhlelo zokukhanya ezinembile kakhulu.

5. Imikhiqizo Yethu Yezintambo Ze-Kovar: Izixazululo Ezithembekile Zezidingo Zakho

5.1 Imininingwane Ephelele

Imboza izinga elijwayelekile (4J29/Kovar) ngobubanzi bentambo obusukela ku-0.10mm kuya ku-5.0mm.

Itholakala ngama-spool, ama-coil, noma ubude bokusika, ngokuhambisana nezindinganiso ze-ASTM F15.

5.2 Izinsizakalo Ezenziwe Ngokwezifiso

Nikeza ububanzi bezintambo ezenziwe ngokwezifiso kanye nokwelashwa kwendawo (ukucwebezela, ukushiswa) ngezidingo ezithile zokuvala.

Lungisa izixazululo zezinhlelo zokusebenza ezincane zokunemba noma ama-oda amakhulu ezimboni.

5.3 Ukulawulwa Kwekhwalithi Okuqinile

Ukuhlolwa kwangaphambi kokulethwa okungu-100%, okuhlanganisa i-coefficient yokwanda kokushisa, ukwakheka, kanye nokuhlolwa kokubekezelelana kobubanzi.

Ukukhiqizwa okuncibilikisiwe nge-vacuum kuqinisekisa ukusebenza okufanayo kanye nobumsulwa obuphezulu.

6. Isiphetho

Intambo yeKovar iyintambo ye-alloy enwebeka kancane engenakufakwa esikhundleni, echazwa amandla ayo okulinganisa ukushisa kanye nokuvala okungenamoya.

Ukusetshenziswa kwayo kabanzi kwezobuchwepheshe, izindiza, kanye nemikhakha yezokwelapha kufakazela ukubaluleka kwayo okusebenzayo kanye nokuthembeka kwayo.

Ucingo lwethu lweKovar olusezingeni eliphezuluimikhiqizo isebenzisa ngokugcwele lezi zinzuzo. Uma udinga ukuvala okuthembekile noma ucingo lwe-alloy olunwebeka kancane, xhumana nathi ukuze uthole izincomo ezenzelwe wena kanye nosekelo lobuchwepheshe.
