NDEGE
Zamlengalenga
Pamene zaka za m'ma 200 zinkapita patsogolo, aluminiyamu inakhala chitsulo chofunikira mu ndege. Chombo cha ndege chakhala chovuta kwambiri kugwiritsa ntchito ma aloyi a aluminiyamu. Masiku ano, monga mafakitale ambiri, mlengalenga amagwiritsa ntchito kwambiri kupanga aluminiyamu.
Chifukwa chiyani musankhe Aluminium Alloy mu Aerospace Viwanda:
Kulemera Kwambiri- Kugwiritsa ntchito zitsulo zotayidwa kumachepetsa kulemera kwa ndege kwambiri. Ndi kulemera kwachitatu kopepuka kuposa chitsulo, kumapangitsa kuti ndege ikhale yolemera kwambiri, kapena kukhala yowotcha mafuta.
Mphamvu Zapamwamba- Mphamvu ya Aluminium imalola kuti isinthe zitsulo zolemera popanda kutaya mphamvu zogwirizana ndi zitsulo zina, ndikupindula ndi kulemera kwake kopepuka. Kuphatikiza apo, zida zonyamula katundu zimatha kugwiritsa ntchito mphamvu za aluminiyamu kuti apange ndege zodalirika komanso zotsika mtengo.
Kukaniza kwa Corrosion- Kwa ndege ndi anthu okwera ndege, dzimbiri ndi zoopsa kwambiri. Aluminiyamu imagonjetsedwa kwambiri ndi dzimbiri komanso malo okhala ndi mankhwala, zomwe zimapangitsa kuti zikhale zofunika kwambiri kwa ndege zomwe zimagwira ntchito m'malo owononga kwambiri apanyanja.
Pali mitundu ingapo ya aluminiyamu, koma ina ndiyoyenera kwambiri kumakampani opanga ndege kuposa ena. Zitsanzo za aluminiyumu yotere ndi izi:
2024- Chigawo choyambirira cha aluminiyamu mu 2024 ndi mkuwa. Aluminiyamu ya 2024 itha kugwiritsidwa ntchito pakafunika mphamvu zazikulu zolimbitsa thupi. Monga aloyi ya 6061, 2024 imagwiritsidwa ntchito pamapiko ndi ma fuselage chifukwa cha zovuta zomwe amalandira panthawi yogwira ntchito.
5052- Chigawo champhamvu kwambiri chamagulu osachiritsika, aluminiyamu 5052 imapereka mwayi wabwino ndipo imatha kukokedwa kapena kupangidwa mosiyanasiyana. Kuphatikiza apo, imapereka kukana kwamadzi amchere m'madzi amchere.
6061- Izi aloyi ali wabwino makina katundu ndipo mosavuta welded. Ndi aloyi wamba kuti agwiritsidwe ntchito wamba ndipo, muzamlengalenga, amagwiritsidwa ntchito popanga mapiko ndi fuselage. Ndizofala makamaka mu ndege zomangira nyumba.
6063- Zomwe zimatchedwa "architectural alloy," 6063 aluminiyamu imadziwika kuti imapereka mawonekedwe omaliza, ndipo nthawi zambiri imakhala yothandiza kwambiri popanga anodizing.
7050- Chisankho chapamwamba cha ntchito zamlengalenga, alloy 7050 amawonetsa kukana kwambiri kwa dzimbiri komanso kulimba kuposa 7075. Chifukwa chakuti imasunga mphamvu zake m'magawo ambiri, 7050 aluminiyamu imatha kupirira fractures ndi dzimbiri.
7068- 7068 aluminium alloy ndiye mtundu wamphamvu kwambiri wa alloy womwe ukupezeka pamsika wamalonda. Yopepuka komanso kukana kwa dzimbiri, 7068 ndi imodzi mwazitsulo zolimba kwambiri zomwe zikupezeka pano.
7075- Zinc ndiye chinthu chachikulu chopangira aluminium 7075. Mphamvu yake ndi yofanana ndi yamitundu yambiri yazitsulo, ndipo ili ndi machinability abwino ndi mphamvu zotopa. Idagwiritsidwa ntchito poyambilira mu ndege za Mitsubishi A6M Zero panthawi ya Nkhondo Yachiwiri Yapadziko Lonse, ndipo ikugwiritsidwabe ntchito poyendetsa ndege mpaka pano.
