Kuponya ndalama kumadziwikanso ngati njira yotayika sera. Njirayi ndi imodzi mwa njira zakale kwambiri zopangira.
Maonekedwe ovuta amatha kupangidwa molondola kwambiri. Kuphatikiza apo, zitsulo zomwe zimakhala zovuta kupanga makina kapena kupanga ndizoyenera kuchita izi. Itha kugwiritsidwa ntchito kupanga magawo omwe sangathe kupangidwa ndi njira zodziwika bwino zopangira, monga masamba a turbine omwe ali ndi mawonekedwe ovuta, kapena mbali za ndege zomwe zimayenera kupirira kutentha kwakukulu.
Ndi zinthu ziti zomwe zimagwiritsidwa ntchito popanga ndalama?
Kupanga chitsanzo- Mapangidwe a sera amapangidwa ndi jekeseni wachitsulo ndipo amapangidwa ngati chidutswa chimodzi. Ma Cores atha kugwiritsidwa ntchito kupanga chilichonse chamkati mwapateni. Zambiri mwazomwezi zimalumikizidwa ndi njira yapakati yolowera sera (sprue, othamanga, ndi risers), kupanga msonkhano wonga mtengo. Dongosolo la gating limapanga njira zomwe chitsulo chosungunula chimathamangira ku nkhungu.
Kupanga nkhungu- Izi "chitsanzo mtengo" imamizidwa mu slurry wa tinthu tating'ono ta ceramic, yokutidwa ndi tinthu coarse kwambiri, kenako zowuma kuti apange chipolopolo cha ceramic kuzungulira mapangidwe ndi gating system. Izi zimabwerezedwa mpaka chipolopolocho chitakhuthala mokwanira kuti chitha kupirira chitsulo chosungunuka chomwe chidzakumana nacho. Kenako chigobacho amachiika mu uvuni ndipo sera amasungunuka n’kusiya chigoba chadongo chomwe chimakhala ngati nkhungu imodzi., choncho dzina "sera yotayika" kuponyera.
Kuthira- nkhungu imatenthedwa kale mu ng'anjo mpaka pafupifupi 1000 ° C (1832°F) ndipo chitsulo chosungunula chimatsanuliridwa kuchokera ku ladle kupita kumalo olowera a nkhungu, kudzaza nkhungu. Kuthira kumatheka pamanja pansi pa mphamvu yokoka, koma njira zina monga vacuum kapena pressure nthawi zina amagwiritsidwa ntchito.
Kuziziritsa- Pambuyo podzaza nkhungu, chitsulo chosungunuka chimaloledwa kuziziritsa ndi kukhazikika mu mawonekedwe a kuponyedwa komaliza. Nthawi yozizira imadalira makulidwe a gawolo, makulidwe a nkhungu, ndi zinthu zogwiritsidwa ntchito.
Kuchotsa kutaya- Chitsulo chosungunuka chikazizira, nkhungu ikhoza kuthyoledwa ndikuponyedwa kuchotsedwa. Chikombole cha ceramic nthawi zambiri chimasweka pogwiritsa ntchito jets zamadzi, koma njira zina zingapo zilipo. Kamodzi kuchotsedwa, mbalizo zimasiyanitsidwa ndi dongosolo la gating ndi macheka kapena kusweka kozizira (kugwiritsa ntchito nayitrogeni wamadzi).
Kumaliza- Nthawi zambiri, kumaliza ntchito monga kupera kapena sandblasting ntchito kusalaza mbali pa zipata. Chithandizo cha kutentha chimagwiritsidwanso ntchito nthawi zina kuumitsa gawo lomaliza.
Njira yopangira ndalama ndiyopindulitsa kwambiri poponya zitsulo zotentha kwambiri zomwe sizingapangidwe, kuponderezedwa, kapena kuumbidwa ndi pulasitala kapena mchenga.
Kuponyera ndalama kumagwiritsidwa ntchito muzamlengalenga ndi mafakitale opanga magetsi kuti apange masamba a turbine okhala ndi mawonekedwe ovuta kapena machitidwe ozizira.. Mabala opangidwa ndi kuponya ndalama amatha kukhala ndi kristalo imodzi (SX), molunjika olimba (DS), kapena masamba ochiritsira a equiaxed.
Mafakitale ena omwe amagwiritsa ntchito magawo omwe amapangidwa ndi ndalama amaphatikizanso zankhondo, zamlengalenga, zachipatala, zodzikongoletsera, ndege, makalabu agalimoto ndi gofu makamaka kuyambira chiyambi chaukadaulo wosindikiza wa 3D.
Ndi kuchuluka kwa kupezeka kwa osindikiza apamwamba kwambiri a 3D, 3D yosindikiza yayamba kugwiritsidwa ntchito popanga nkhungu zazikulu zoperekera nsembe zomwe zimagwiritsidwa ntchito popanga ndalama. Planetary Resources yagwiritsa ntchito njirayi kusindikiza nkhungu kuti ikhale ya satellite yaying'ono, yomwe kenako imamizidwa mu ceramic kuti ipange ndalama zopangira mabasi a titaniyamu okhala ndi tanki yofunikira komanso njira zolumikizira chingwe..
Zigawo zoponya magalimoto
Zida zopangira ndege
Zowonjezera zida zamafuta ndi gasi
Zida zoponyera zida zankhondo
