Waya wa Kovarndi waya wapadera wa aloyi wochepera kukula, wodziwika bwino chifukwa cha mawonekedwe ake apadera ofanana ndi kutentha.

Imagwira ntchito yofunika kwambiri m'mafakitale olondola kwambiri monga zamagetsi, ndege, ndi zida zachipatala. Bukuli likuyankha funso lofunika kwambiri la kodi waya wa Kovar ndi chiyani ndipo limafotokoza momwe amagwiritsidwira ntchito, pamodzi ndi mayankho athu apamwamba a waya wa Kovar.

1. Kodi waya wa Kovar ndi chiyani?

1.1 Tanthauzo Lalikulu

Waya wa Kovar ndi waya wa aloyi wachitsulo-nickel-cobalt wosungunuka ndi vacuum, wopangidwa kuti uzitha kuwongolera kutentha bwino.

Ubwino wake waukulu ndikugwirizana ndi kuchuluka kwa kutentha kwa galasi la borosilicate ndi zoumbaumba, zomwe zimathandiza kutseka bwino popanda chotchinga.

1.2 Kapangidwe Koyenera ka Mankhwala

Waya wa Kovar uli ndi kapangidwe kowongoleredwa bwino kuti utsimikizire kuti magwiridwe antchito ake ndi okhazikika:

- Iron (Fe): 53-54% (yokwanira)

- Nikeli (Ni): 28.5-29.5%

- Cobalt (Co): 16.8-17.8%

Zinthu zotsatizana (Mn, Si, C) zimangolekeredwa mkati mwa 0.5% max chilichonse.

1.3 Miyezo Yofunika & Maudindo

Ikutsatira miyezo yapadziko lonse lapansi kuti iwonetsetse kuti ntchito zake zonse zikugwirizana.

- ASTM F15 (muyezo waukulu wa zinthu za aloyi za Kovar)

- UNS K94610, Werkstoff Nr. 1.3981 (matchulidwe apadziko lonse lapansi)

Imadziwikanso kuti 4J29 mu miyezo yaku China, imatha kusinthidwa ndi Nilo-K m'madera ena.

2. Makhalidwe Ofunika a Waya wa Kovar

2.1 Kuwonjezeka kwa Kutentha Kochepa & Kokhazikika

Kuchuluka kwake kwa kutentha (4.6-5.2×10⁻⁶/℃, 20-400℃) kumafanana bwino ndi galasi la borosilicate.

Izi zimachotsa ming'alu ya kupsinjika panthawi yotenthetsera ndi kuzizira, zomwe zimapangitsa kuti zitsekedwe bwino.

2.2 Kuthekera Kwambiri Kogwirira Ntchito

Ili ndi mphamvu yolimba ndipo imatha kukokedwa mu mawaya osalala, kupindika, ndi kuwotcherera mosavuta.

Yoyenera kujambula mozizira, kupondaponda, ndi njira zosiyanasiyana zowotcherera (argon arc, laser welding).

2.3 Kutentha Kwambiri ndi Kukhazikika kwa Kutentha

Imasunga magwiridwe antchito okhazikika pa kutentha mpaka 450℃, ndi malo osungunuka a 1450℃.

Amapanga zisindikizo zosalowa mpweya zokhala ndi galasi/zoumba, zofunika kwambiri pa ntchito zotsukira mpweya komanso zodalirika kwambiri.

3. Waya wa Kovar vs. Mawaya Ofanana a Alloy: Tebulo Loyerekeza

Gome ili m'munsimu likuwonetsa ubwino wapadera wa waya wa Kovar poyerekeza ndi waya wa constantan ndi cupro nickel:

4. Kodi waya wa Kovar umagwiritsidwa ntchito bwanji? Zochitika Zofunikira Zogwiritsira Ntchito

4.1 Kupaka Makompyuta ndi Ma Semiconductor

Amagwiritsidwa ntchito ngati mawaya otsogolera a machubu otayira mpweya, ma transistors, ma diode, ndi ma circuits ophatikizidwa.

Zimathandiza kutseka zinthu zotenthetsera ndi magalasi, kuteteza zinthu zamkati ku chinyezi ndi kuipitsidwa.

4.2 Ndege ndi Maulendo a Ndege

Yogwiritsidwa ntchito mu zida zamagetsi za ndege ndi zida zolumikizirana ndi satelayiti.

Kukhazikika kwake kutentha kumapirira kusinthasintha kwakukulu kwa kutentha m'malo ozungulira ndege.

4.3 Zipangizo Zachipatala

Amagwiritsidwa ntchito mu masensa azachipatala, zida zodziwira matenda, ndi zolumikizira zotchingira mpweya.

Imakwaniritsa zofunikira zokhudzana ndi chilengedwe komanso kudalirika pa ntchito zachipatala.

4.4 Zipangizo Zowunikira ndi Zotsukira Madzi

Amagwiritsidwa ntchito mu zisindikizo zagalasi kukhala zitsulo pa ulusi wa kuwala, machubu a microwave, ndi zida za X-ray.

Zimaonetsetsa kuti mpweya sulowa bwino komanso kutentha kumafanana ndi makina owunikira olondola kwambiri.

5. Zogulitsa Zathu za Kovar Waya: Mayankho Odalirika Okhudzana ndi Zosowa Zanu

5.1 Mafotokozedwe Athunthu

Imaphimba mtundu wokhazikika (4J29/Kovar) ndi waya wozungulira kuyambira 0.10mm mpaka 5.0mm.

Imapezeka mu spools, coils, kapena kutalika kodulidwa, mogwirizana ndi miyezo ya ASTM F15.

5.2 Ntchito Zopangidwira Makonda

Perekani ma waya ozungulira ndi ma treatment apamwamba (plating, oxidation) kuti mugwiritse ntchito potseka zinthu zinazake.

Konzani njira zothetsera mavuto pogwiritsa ntchito njira zazing'ono kapena maoda akuluakulu a mafakitale.

5.3 Kulamulira Kwabwino Kwambiri

Kuyesa 100% isanaperekedwe, kuphatikizapo kuwunikira kuchuluka kwa kutentha, kapangidwe kake, ndi kulekerera kwa dayamita.

Kupanga kosungunuka ndi vacuum kumatsimikizira kuti zinthu zimagwira ntchito mofanana komanso kuti zinthuzo ndi zoyera kwambiri.

6. Mapeto

Waya wa Kovar ndi waya wosasinthika wa alloy wocheperako, womwe umatanthauzidwa ndi mphamvu zake zofananira kutentha komanso kutseka kwa hermetic.

Kugwiritsa ntchito kwake kwambiri pa zamagetsi, ndege, ndi zamankhwala kumatsimikizira kufunika kwake kothandiza komanso kudalirika.

Waya wathu wapamwamba kwambiri wa KovarZogulitsazi zimagwiritsa ntchito bwino maubwino awa. Ngati mukufuna kutseka kodalirika kapena waya wa aloyi wosakulirapo, titumizireni ulalo kuti mupeze malangizo anu ndi chithandizo chaukadaulo.
