Zigawo za aluminiyamu

Kufotokozera Kwachidule:

Aluminium alloy ndi yofala kwambiri m'moyo wathu, zitseko zathu ndi mazenera, bedi, ziwiya zophikira, tableware, njinga, magalimoto ndi zina. Zokhala ndi alloy aluminium.

Chiyambi cha zigawo za Aluminium alloy

Aluminiyamu aloyi ndi aloyi momwe zotayidwa (AL) ndi zitsulo ambiri.
Zomwe zimapangidwa ndi aloyi ndi mkuwa, magnesium, manganeness, silicon ndi zinc iliyonse.
Pali magulu awiri akuluakulu, omwe ndi ma aloyi otayira ndi ma aloyi opangidwa, onsewa amagawika m'magulu omwe amatha kuchiritsidwa ndi kutentha komanso osachiritsika.

Kugwiritsa ntchito zida za Aluminium alloy

Aluminiyamu aloyi wamba kwambiri m'moyo wathu, zitseko ndi mazenera, bedi, ziwiya kuphika, tableware, njinga, magalimoto etc. Muli aloyi zotayidwa.
Aluminiyamu wamba pakugwiritsa ntchito moyo.
Ma aluminiyamu aloyi okhala ndi katundu wambiri amadziwitsa uinjiniya mumapangidwe.
Kusankha aloyi yoyenera kuti igwiritsidwe ntchito kumaphatikizapo kulingalira za mphamvu yake yokhazikika, kachulukidwe, ductility, kupangika, kugwirira ntchito, kutenthedwa ndi dzimbiri kuti igwire.
Aluminiyamu alloy amagwiritsidwa ntchito kwambiri mu ndege chifukwa cha mphamvu yayikulu ya kulemera kwake.

Aluminium alloys motsutsana ndi chitsulo

Ma aluminiyamu aloyi amakhala ndi zotanuka modulus pafupifupi 70GPa, yomwe ili pafupifupi gawo limodzi mwa magawo atatu a zotanuka zamitundu yambiri yazitsulo ndi zitsulo.
Chifukwa chake, pa katundu wopatsidwa, gawo kapena gawo lopangidwa ndi aloyi ya aluminiyamu lidzakwera mtengo kwambiri kuposa gawo lachitsulo lofanana ndi mawonekedwe.
Kuwala khalidwe, mphamvu mkulu, dzimbiri, kukana, zosavuta kupanga, kuwotcherera.
Ma aloyi omwe amapangidwa makamaka ndi aluminiyamu akhala ofunikira kwambiri popanga zamlengalenga kuyambira pomwe ndege zokhala ndi zikopa zachitsulo zidakhazikitsidwa.Aluminium magnesium alloys onse ndi opepuka kuposa ma aloyi ena a aluminiyamu ndipo amatha kuyaka pang'ono kuposa aloyi omwe ali ndi kuchuluka kwambiri kwa magnesium.

Kutengera kutentha kwa zigawo za Aluminium alloy

Nthawi zambiri, kukhudzidwa kwa chitsulo pakutentha kumaganiziridwanso, ngakhale njira yochitira msonkhano wanthawi zonse yokhudzana ndi kutentha imakhala yovuta chifukwa aluminiyumu, mosiyana ndi chitsulo, imasungunuka popanda kufiira koyamba.

Kusamalira mbali za Aluminium alloy

Ma aluminiyamu aloyi amadzipangitsa kuti aziwoneka bwino m'malo owuma chifukwa chopanga chitsulo chowoneka bwino, choteteza cha aluminium oxide.Pamalo onyowa, dzimbiri la galvanic limatha kuchitika ngati aloyi ya aluminiyamu imayikidwa pamagetsi ndi zitsulo zina zomwe zimatha kuwononga kwambiri kuposa aluminiyumu.

Kugwiritsa ntchito zigawo za Aluminium alloy

Main alloying zinthu ndi mkuwa, pakachitsulo, magnesium, nthaka, manganese, sekondale alloying zinthu ndi nickle, chitsulo, titaniyamu, chromium, lithiamu, etc.
Aluminiyamu alloy ndi omwe amagwiritsidwa ntchito kwambiri m'mafakitale osapanga zitsulo zosapanga dzimbiri mu ndege, zakuthambo, magalimoto, kupanga makina, kutumiza ndipo akhala akugwiritsidwa ntchito kwambiri m'makampani opanga mankhwala.
Aluminiyamu kachulukidwe aloyi ndi otsika, koma mphamvu ndi mkulu.

Aluminium alloy classification

Ma alloys omwe amagwiritsidwa ntchito poponya kufa tsopano amapangidwa ndi aluminium alloy.Lili ndi mphamvu zakuthupi zowunikira komanso kukana kwa dzimbiri komanso makina, komanso kuyendetsa bwino kwa kutentha.Aluminiyamu aloyi akhoza kugawidwa mu processing ndi kuponyera zipangizo, ndipo akhoza m'gulu la mitundu iwiri: kutentha mankhwala zotayidwa aloyi ndi sanali kutentha mankhwala zotayidwa aloyi zipangizo mu processing zipangizo.Die kuponyera zotayidwa aloyi ndi zinthu kuponyera, ndi aloyi zotayidwa amene ntchito ambiri si oyenera kutentha kutentha chifukwa kukonzedwa mu mankhwala kudzera kufa kuponyera ndondomeko.

Aluminium silicon mndandanda
The general aluminium alloy, monga ADC1, imagwira ntchito ku makoma akulu, owonda komanso mawonekedwe ovuta.Zomwe zili muzinthu za silicon pafupi ndi eutectic point ndikupanga madzi osungunuka osungunuka ndi abwino, ali ndi mphamvu yabwino kwambiri, kukana kwa dzimbiri, kutsika kwa kutentha kwapamwamba, kuwonjezeka kwa kutentha ndi gawo locheperapo 2.65g/cm3, etc.Komabe, sikwabwino kukhala wosasunthika komanso wosasunthika, ndipo anodic oxidation si yabwino.Ngati zinthu zoponyera sizili zoyenera, madzi osungunuka amachedwa.

Aluminium silicon mkuwa
ADC12 aloyi ali mu Al-Si aloyi kuwonjezera mkuwa aloyi chinthu, ndi ambiri ankagwiritsa ntchito chifaniziro cha kufa kuponyera zotayidwa aloyi, castability ake kwambiri ndi katundu makina, koma osauka dzimbiri kukana.

Aluminium-Silicon-Magnesium mndandanda
ADC3 zotayidwa aloyi ali mu Al-Si aloyi kuwonjezera aloyi zinthu monga Mg, Fe, ndi katundu kwambiri makina, kukana dzimbiri ndi castability wabwino, koma pamene zili chitsulo zosakwana 1% zomatira zosavuta ndi nkhungu zitsulo, aloyi ambiri ntchito.Ma aloyi ena a ADC5 ndi ADC 6, omwe amadziwikanso kuti aluminium-magnesium alloys, ndi amphamvu kwambiri, osagwirizana ndi corrision komanso opangidwa ndi makina, ndipo ndi abwino kwambiri mu aloyi ya aluminiyamu.Komabe, chifukwa cha kuchuluka kwa kulimba komanso kukulitsa kwamafuta, kutulutsa kwa aloyi sikwabwino.A zamadzimadzi komanso osauka, sachedwa kumamatira chodabwitsa ndi imfa ya zitsulo zonyezimira pambuyo akupera, choncho ndi oyenera anodic makutidwe ndi okosijeni mankhwala, ndi zonyansa zina monga chitsulo, pakachitsulo ndi zina zotero bwanji padziko maonekedwe.
Mayiko osiyanasiyana ali ndi maudindo osiyanasiyana a aluminiyamu ya die-cast, monga Axxx ndi chitsanzo cha America, ADCxx ndi chitsanzo cha Japan, LMxx ndi British model, YLxxx ndi chitsanzo cha China.

Chithandizo chapamwamba cha magawo a aluminiyamu aloyi
Kuchuluka kwa anodic oxidation.
Nthawi yomweyo, ili ndi zinchito ndi yokongola pamwamba, ndipo ambiri anodized zotayidwa aloyi ndi za 2-25um.
Kukhazikika kwapamwamba komanso anti-kuvala aluminium alloy castings ali ndi makulidwe a 25-75um pamwamba.Aluminium alloy oxide wosanjikiza amatha kukonzedwa ndikupangidwa.
Mitundu yamitundu yonse siyikhala yochititsa chidwi ikakokedwa ndi okosijeni, chifukwa chake imatha kugwiritsidwa ntchito bwino m'zigawo zosiyanasiyana za zida zamagetsi.
Phosfide/chromium.
Phosphatification ndi chotchinga chopanda chitsulo komanso chocheperako chomwe chimapanga chosanjikiza cholowa m'malo mwachitsulo kudzera pamagulu a phosphorous.
Zimagwira ntchito ku chitsulo, aloyi ya zinki, aloyi ya aluminiyamu ndi zinthu zina, zomwe zingapangitse kukana kwa dzimbiri komanso kukana kuvala.
Nembanembayo pakali pano ndi yabwino kugonjetsedwa ndi filimu yotembenuza aluminiyamu, kotero imatha kuchitidwa ngati ❖ kuyanika kumodzi pamwamba pa aluminiyumu alloy.
The micro-arc oxidation.
Kugwiritsa ntchito magetsi ochulukirapo pazigawo za aluminiyamu kupanga filimu ya ceramic pamwamba, kulimba kwa zokutira ndi kukana abrasion ndikokwera kwambiri, kukana kwa dzimbiri komanso kwapadera.
Mphepete mwa nyanja ndi yabwino kuposa anode.
Microarc membrane imapangidwa ndi magulu atatu:
Wosanjikiza woyamba ndi filimu yopyapyala yolumikizidwa pamwamba pa aluminiyumu, yomwe ili pafupifupi 3 mpaka 5um.
Gawo lachiwiri ndilo gawo lalikulu la nembanemba, lomwe liri pafupi 150 mpaka 250um.Chosanjikiza chachikulu chimakhala cholimba kwambiri ndipo porosity ndi yaying'ono komanso yolimba kwambiri.
Chigawo chachitatu ndi chomaliza pamwamba.Chosanjikiza ichi ndi chotayirira komanso chovuta, motero chimasinthidwa ndikuchotsedwa ntchito pagawo lalikulu.
The alunina microarc oxidation amafananizidwa ndi anodic oxidation.
Kugwiritsa ntchito ukadaulo wa microarc oxidation:
Zida zoyendetsa ndege: zigawo za pneumatic ndi zigawo zosindikizira.
Zigawo zamagalimoto: pisitoni nozzle
Zida zapakhomo: bomba, chitsulo chamagetsi.
Zida zamagetsi: mita ndi zida zamagetsi zamagetsi.
