INCONEL 718 ndi aloyi yamphamvu kwambiri, yosagwira dzimbiri yochokera ku nickel. Imapangidwa makamaka ndi nickel, yokhala ndi chromium yambiri, chitsulo, ndi zinthu zina zochepa monga molybdenum, niobium, ndi aluminiyamu. Aloyi imadziwika ndi mphamvu zake zabwino kwambiri zamakaniko, kuphatikizapo kulimba kwambiri, kukhuthala, ndi kutopa, komanso kulimba bwino komanso kukana ming'alu ndi kusintha kwa kayendedwe ka madzi. INCONEL 718 imatsutsanso dzimbiri kwambiri, ngakhale kutentha kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo ovuta monga ndege, kukonza mankhwala, ndi ntchito zapamadzi. Imagwiritsidwa ntchito kwambiri popanga zida za turbine ya gasi, injini za roketi, ndi zida zosiyanasiyana zomwe zimakhala ndi mphamvu zambiri komanso zovuta kwambiri.
INCONEL 718 ndi superalloy yopangidwa ndi nickel yomwe imadziwika ndi mphamvu zake zapadera zamakaniko pa kutentha kwakukulu. Imapangidwa makamaka ndi nickel, pamodzi ndi zinthu zina zochepa monga chromium, iron, niobium, molybdenum, ndi aluminiyamu. INCONEL 718 imapereka mphamvu zambiri, kukana dzimbiri, komanso kukana okosijeni, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo ovuta kwambiri monga injini za ndege ndi gasi. Imagwiritsidwanso ntchito kwambiri m'magwiritsidwe ntchito omwe amafunikira kukana kutentha kwambiri, monga zosinthira kutentha ndi ma reactor a nyukiliya.
Kuti mudziwe zambiri chonde onani ulalo wa tsamba lathu lawebusayiti:https://www.jxbsc-alloy.com/inconel-alloy-718-uns-n07718w-nr-2-4668-product/
Inde, alloy718 ndi INCONEL 718 amatanthauza mtundu womwewo wa superalloy yochokera ku nickel. INCONEL 718 ndi chizindikiro cholembetsedwa cha Special Metals Corporation, chomwe ndi dzina lapadera la alloy iyi. Chifukwa chake, alloy 718 nthawi zambiri imatchedwa INCONEL 718.
INCONEL 718 ndi UNS N07718. Ndi superalloy yopangidwa ndi nickel yomwe imakhala ndi mphamvu zambiri, yolimba, komanso yopangidwa bwino, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo osiyanasiyana oyendera ndege, kukonza mankhwala, ndi malo ena otentha kwambiri.
Palibe chinthu chofanana ndi INCONEL 718 chifukwa ndi aloyi yapadera yopangidwa ndi nickel. Komabe, pali aloyi ena angapo opangidwa ndi nickel omwe ali ndi makhalidwe ofanana ndipo angagwiritsidwe ntchito ngati njira zina m'magwiritsidwe ena. Zina mwa aloyi awa ndi awa:
- Rene 41
- Waspaloy
- Hastelloy X
- Nimonic 80A
- Haynes 230
Ma alloy amenewa ali ndi mphamvu zolimba komanso zosagwirizana ndi dzimbiri mofanana ndi INCONEL 718 ndipo nthawi zambiri amagwiritsidwa ntchito mofanana. Komabe, ndikofunikira kuganizira zofunikira zinazake ndikufunsana ndi mainjiniya a zipangizo kapena akatswiri a zitsulo kuti adziwe njira yoyenera kwambiri yogwiritsira ntchito inayake.
Ngakhale kuti INCONEL 718 imadziwika ndi makhalidwe ake abwino komanso ntchito zake zosiyanasiyana, ili ndi zovuta zingapo, kuphatikizapo:
Mtengo: INCONEL 718 ndi yokwera mtengo poyerekeza ndi ma alloy ena, makamaka chifukwa cha kuchuluka kwa nickel komanso njira yovuta yopangira. Izi zingapangitse kuti ikhale yotsika mtengo kwambiri pa ntchito zina zomwe zili ndi bajeti yochepa.
Kutha Kukonza: INCONEL 718 ndi chinthu chovuta kuchipanga. Chimakonda kugwira ntchito molimbika, zomwe zikutanthauza kuti zida zodulira zimatha kutha msanga, zomwe zimapangitsa kuti ndalama zogwiritsira ntchito zida ziwonjezeke komanso kuti ntchito zichepe.
Kutha Kuthira: INCONEL 718 ili ndi kuthekera kochepa kothira ndipo imafuna njira zapadera komanso njira zothira bwino. Kuthira kumatha kupangitsa kuti pakhale ming'alu ndi zolakwika ngati sizichitika bwino, zomwe zingafooketse kapangidwe kake konse.
Kukula kwa kutentha: INCONEL 718 ili ndi kuchuluka kwa kutentha komwe kumawonjezeka, zomwe zikutanthauza kuti imatha kukula ndikuchepa kwambiri ndi kusintha kwa kutentha. Izi zingayambitse kusakhazikika kwa mawonekedwe m'magwiritsidwe ena, zomwe zimafuna kuganizira mosamala kapangidwe kake.
Ngakhale kuti pali zovuta izi, INCONEL 718 imagwiritsidwabe ntchito kwambiri m'mafakitale osiyanasiyana otentha kwambiri, monga mafakitale a ndege, mphamvu, ndi mafuta ndi gasi, komwe kuphatikiza kwake kwapadera kumaposa zoletsa izi.
