Ma superalloy opangidwa ndi Nickel ndi gulu la zida zogwira ntchito kwambiri zomwe zimapangidwira mphamvu zapadera zamakina, kukana kukwawa, komanso kukhazikika kwamapangidwe pamatenthedwe okwera, omwe amakhala pamwamba pa 540 ° C (1000 ° F). Mawu oti "opangidwa" amatanthauza kuti ma alloyswa amapangidwa kukhala mawonekedwe awo omaliza kudzera munjira za thermomechanical monga kufota, kugudubuza, kapena kutulutsa, zomwe zimapangitsa kuti pakhale mbewu yabwino, yolunjika yomwe imapereka mphamvu zapamwamba komanso kutopa poyerekeza ndi anzawo. Ndiwo msana wa zigawo zotentha kwambiri zozungulira mumlengalenga ndi magetsi, kumene kulephera sikungatheke.

Nickel-based based corrosion-resistant alloys ndi gulu lazitsulo zapamwamba zomwe zimapangidwa kuti zipirire malo owononga kwambiri. Maziko awo ndi matrix a nickel (Ni), omwe mwachibadwa amakhala osagwirizana ndi zowononga zambiri, zosakanikirana ndi zinthu zina zazikulu-makamaka chromium (Cr), molybdenum (Mo), ndipo nthawi zina zamkuwa (Cu) ndi nayitrogeni (N) - kupanga banja losunthika komanso lamphamvu lazinthu zogwiritsa ntchito kwambiri mankhwala ndi mafakitale. Ndiwo njira yothetsera pamene zitsulo zosapanga dzimbiri sizikhala zokwanira.

Chitsulo chopangidwa ndi zitsulo zotentha kwambiri ndi kalasi yazitsulo zokhala ndi chitsulo (Fe) monga chinthu chachikulu, chopangidwa kuti chikhale ndi mphamvu zamakina komanso kukana kuwonongeka (monga makutidwe ndi okosijeni) pa kutentha kwakukulu, komwe kumakhala pakati pa 540 ° C mpaka 760 ° C (1000 ° F mpaka 1400 ° F). Mawu akuti "opangidwa" akuwonetsa kuti amapangidwa ndi njira za thermomechanical monga kugudubuza kotentha, kupangira, kapena kutulutsa, komwe kumawongolera ma microstructure awo kuti apereke kuphatikizika kwamphamvu, ductility, ndi kutheka. Amakhala ngati njira yotsika mtengo komanso yosunthika kwambiri pamagwiritsidwe osiyanasiyana a kutentha kwambiri, kutsekereza kusiyana kwa magwiridwe antchito pakati pa zitsulo zosapanga dzimbiri ndi faifi tambala kapena ma superalloys opangidwa ndi cobalt okwera mtengo kwambiri.

Ma superalloys opangidwa ndi cobalt ndi gulu la zida zachitsulo zogwira ntchito kwambiri zomwe zimapangidwira kuti zikhalebe ndi mphamvu zamakina, kukhazikika kwapamtunda, komanso kukana kwa dzimbiri pa kutentha kwambiri, nthawi zambiri kuposa zomwe ma superalloys opangidwa ndi faifi tambala amayamba kufooka. Ndizinthu zapangondya pazinthu zofunika kwambiri m'malo ovuta kwambiri, makamaka muzamlengalenga, ma turbines amafuta am'mafakitale, ndi ma implants azachipatala. Kuchita kwawo kwapamwamba kumachokera ku mphamvu ya cobalt-chromium matrix komanso kuchuluka kwa tinthu tating'ono ta carbide tolimba.
