I-5J1480 i-alloy enembile 5J1480 i-superalloy yensimbi I-alloy yensimbi-nickel Ngokwezinto ze-matrix, ingahlukaniswa ibe yi-superalloy esekelwe ensimbini, i-superalloy esekelwe e-nickel kanye ne-superalloy esekelwe e-cobalt. Ngokwenqubo yokulungiselela, ingahlukaniswa ibe yi-superalloy eguquliwe, i-superalloy ekhipha i-casting kanye ne-powder metallurgy superalloy. Ngokwendlela yokuqinisa, kunezinhlobo zokuqinisa isixazululo esiqinile, uhlobo lokuqinisa imvula, uhlobo lokuqinisa ukusabalala kwe-oxide kanye nohlobo lokuqinisa i-fiber. Ama-alloy okushisa okuphezulu asetshenziswa kakhulu ekwenziweni kwezingxenye zokushisa okuphezulu njenge-turbine blades, i-guide vanes, ama-turbine disc, ama-compressor discs anomfutho ophezulu kanye namakamelo okushisa ezindiza, ama-turbine egesi asemanzini nasezimbonini, futhi asetshenziswa nasekukhiqizweni kwezimoto zezindiza, izinjini zamarokhethi, ama-reactor enuzi, imishini ye-petrochemical kanye namadivayisi okuguqula amandla amalahle kanye namanye.

ukusetshenziswa kwezinto ezibonakalayo

I-5J1480 thermal bimetal 5J1480 i-precision alloy 5J1480 i-superalloy i-iron-nickel alloy i-superalloy ibhekisela ohlotsheni lwezinto zensimbi ezisekelwe ku-iron, nickel kanye ne-cobalt, ezingasebenza isikhathi eside ekushiseni okuphezulu okungaphezu kuka-600 ℃ nangaphansi kokucindezeleka okuthile; futhi zinamandla aphezulu okushisa aphezulu, ukumelana okuhle kwe-oxidation kanye nokumelana nokugqwala, ukusebenza okuhle kokukhathala, ukuqina kokuphuka kanye nezinye izakhiwo eziphelele. I-superalloy iyisakhiwo esisodwa se-austenite, esinokuqina okuhle kwesakhiwo kanye nokuthembeka kwenkonzo emazingeni okushisa ahlukahlukene.

Ngokusekelwe ezicini zokusebenza ezingenhla, kanye nezinga eliphezulu lokuhlanganiswa kwama-superalloy, aziwa nangokuthi “ama-super alloy”, kuyinto ebalulekile esetshenziswa kabanzi ezindizeni, ezindizayo, kuphethiloli, embonini yamakhemikhali, kanye nasemikhumbini. Ngokwezinto ze-matrix, ama-superalloy ahlukaniswe ngama-superalloy asekelwe ensimbini, asekelwe ku-nickel, asekelwe ku-cobalt kanye namanye ama-superalloy. Izinga lokushisa lesevisi lama-alloy asekelwe ensimbini ngokuvamile lingafinyelela ku-750 ~ 780°C kuphela. Ezingxenyeni ezingamelani nokushisa ezisetshenziswa emazingeni okushisa aphezulu, kusetshenziswa ama-alloy asekelwe ku-nickel kanye nama-refractory metal. Ama-superalloy asekelwe ku-nickel athatha isikhundla esikhethekile nesibalulekile kuyo yonke insimu yama-superalloy. Asetshenziswa kabanzi ukukhiqiza izingxenye ezishisa kakhulu zezinjini zezindiza kanye nama-turbine ahlukahlukene egesi yezimboni. Uma amandla aqinile angu-150MPA-100H esetshenziswa njengendinganiso, izinga lokushisa eliphakeme kakhulu elingamelana nama-alloy e-nickel lingu->1100°C, kuyilapho ama-alloy e-nickel engaba ngu-950°C, kanti ama-alloy asekelwe ensimbini angaphansi kuka-850°C, okungukuthi, ama-alloy asekelwe e-nickel aphakeme ngokufanayo ngo-150°C kuya ku-250°C. Ngakho-ke abantu babiza i-alloy ye-nickel ngokuthi inhliziyo yenjini. Njengamanje, ezinjinini ezithuthukisiwe, ama-alloy e-nickel abalelwa engxenyeni yesisindo esiphelele. Akuzona nje ama-blade e-turbine namakamelo okushisa, kodwa nama-diski e-turbine ngisho nezigaba zokugcina zama-compressor blades aseqalile ukusebenzisa ama-alloy e-nickel. Uma kuqhathaniswa nama-alloy ensimbi, izinzuzo zama-alloy e-nickel yilezi: izinga lokushisa eliphezulu lokusebenza, isakhiwo esizinzile, izigaba ezingonakalisi kakhulu kanye nokumelana okuphezulu ne-oxidation kanye nokugqwala. Uma kuqhathaniswa nama-alloy e-cobalt, ama-alloy e-nickel angasebenza ngaphansi kokushisa okuphezulu kanye nokucindezeleka, ikakhulukazi uma kwenzeka ama-blade ahambayo.

I-5J1480 thermal bimetal 5J1480 i-precision alloy 5J1480 i-superalloy yensimbi ne-nickel Izinzuzo ezishiwo ngenhla ze-nickel alloy zihlobene nezinye zezakhiwo zayo ezinhle kakhulu. I-Nickel iyisakhiwo se-cubic esigxile ebusweni esinobukhulu obuphezulu kakhulu

Ukuqina, akukho ukuguqulwa kwe-allotropic kusuka ekushiseni kwegumbi kuya ekushiseni okuphezulu; lokhu kubaluleke kakhulu ekukhetheni njengezinto ze-matrix. Kwaziwa kahle ukuthi isakhiwo se-austenitic sinochungechunge lwezinzuzo ngaphezu kwesakhiwo se-ferrite.

I-Nickel inamandla aphezulu okuqina kwamakhemikhali, ayibi ngaphansi kwama-degrees angu-500, futhi ayithinteki umoya ofudumele, amanzi kanye nezinye izixazululo zikasawoti emanzini emazingeni okushisa esikoleni. I-Nickel incibilika kancane ku-sulfuric acid kanye ne-hydrochloric acid, kodwa ngokushesha ku-nitric acid.

I-Nickel inekhono elikhulu lokuhlanganisa, futhi ngisho nokwengeza izinhlobo ezingaphezu kweshumi zezinto zokuhlanganisa akubonakali kuyizigaba eziyingozi, okunikeza amathuba angaba khona okuthuthukisa izakhiwo ezahlukene ze-nickel.

Nakuba izakhiwo zemishini ze-nickel emsulwa zingaqinile, i-plasticity yayo inhle kakhulu, ikakhulukazi ekushiseni okuphansi, i-plasticity ayishintshi kakhulu.

Izici kanye nokusetshenziswa: ukuzwela kokushisa okumaphakathi kanye nokumelana okuphezulu. Inzwa yokushisa ekulinganisweni kokushisa okumaphakathi kanye nemishini yokulawula okuzenzakalelayo
