Umehluko wokwakheka kwezinto
Ama-alloys asekelwe ku-cobalt asebenzisa i-cobalt (Co), i-chromium (Cr), i-molybdenum (Mo), njll njengezakhi eziyinhloko, lapho i-cobalt ibala inani eliphakeme, kanye nenani elithile lensimbi (Fe), i-carbon (C) nezinye izakhi nazo zengezwe; okusekelwe ku-nickel I-alloy isebenzisa i-nickel (Ni) njengento eyinhloko, futhi yengeza i-chromium (Cr), i-molybdenum (Mo), ithusi (Cu), i-titanium (Ti), i-niobium (Nb) nezinye izakhi.
Umehluko wokucutshungulwa
Ama-alloys asekelwe ku-cobalt anomsebenzi omuhle wokuqinisa kanye nezakhiwo zokuthambisa, futhi kulula ukucutshungulwa abe yizimo ezihlukahlukene. Zilungele izingxenye zomshini zisebenzisa ama-alloys asekelwe ku-cobalt. Ama-alloys asekelwe ku-nickel anokucutshungulwa okuhle futhi kulula ukuwenza, uku-extrusion kanye nokucubungula kwe-rotor, futhi afanele izingxenye zomshini. Ukuthuthukiswa nokuthuthukiswa kwemishini yamandla anesivinini esikhulu esebenzisa ama-alloys asekelwe ku-nickel.
1. Ukwelashwa kokushisa: Womabili ama-alloys asezingeni eliphezulu adinga ukwelashwa kokushisa. Bobabili bamukela uhlelo lokwelapha ukushisa lokwelashwa kwesisombululo esiqinile + ukwelashwa kokuguga. Ubunzima benqubo yokwelapha ukushisa kuyafana.
2.Ukuqina: Womabili ama-alloys asezingeni eliphezulu ane-weldability enhle. Ngesikhathi se-brush seal welding, ukushisa kulula ukunqwabelana futhi kubangele ukubola. Kunconywa ukusebenzisa izinto ezisekelwe ku-cobalt, ezine-conductivity ephezulu ye-thermal, i-conductivity eqinile yokushisa, i-coefficient encane yokwandisa, nokuguqulwa okuncane. , amandla e-welding fusion angcono.
3.Ukuguqula ukucubungula: Ukucubungula ukuphenduka okugculisayo kungenziwa.
Womabili ama-alloys asezingeni eliphezulu anokusebenza kahle.
Umehluko wokusebenza
1.Ukumelana nokugqwala:
Ama-alloys asekelwe ku-Cobalt anokumelana okuhle kakhulu kokugqoka, ukumelana nokugqwala kanye nezindawo zokushisa okuphezulu, futhi angakwazi ukugcina ukusebenza okuzinzile ezindaweni ezimbi kakhulu njenge-asidi eqinile, i-alkali eqinile, izinga lokushisa eliphezulu nokucindezela okukhulu, futhi ifaneleka ukukhiqiza izingxenye ezidinga ukumelana nemithwalo ephezulu kanye nezimo ezimbi kakhulu;
Ama-alloys asekelwe ku-nickel anokumelana nokugqwala okuhle futhi angagcina ukuzinza nobuqotho ezinhlobonhlobo zemithombo yezindaba ebolayo. Futhi banezindawo ezinhle kakhulu zokushisa okuphezulu futhi bangagcina amandla aphezulu kanye nokuqina ezindaweni ezinezinga eliphezulu lokushisa. Kodwa ayilungele imidiya e-acidified egqwalile.
2.Ukuzinza kwe-thermal: Ama-alloys asekelwe ku-cobalt anezakhiwo ezingcono zokushisa okuphezulu kune-alloys esekelwe ku-nickel futhi angasetshenziswa emazingeni okushisa angaphezu kuka-1200°C isikhathi eside, kuyilapho ama-alloys asekelwe ku-nickel ngokuvamile angasetshenziswa kuphela cishe ku-1000°C. Ama-alloys asekelwe ku-cobalt anamaphuzu aphezulu okuncibilika kanye nokuhamba kwe-thermal, ukunwetshwa okuncane kokushisa ngemva kokushisa, futhi kunezinzuzo ekuzinzeni kokushisa; Ama-alloys asekelwe ku-nickel anokumelana kangcono ne-oxidation kanye nokugqwala, kodwa ezindaweni ezinokushisa okuphezulu, i-cobalt I-alloy eyisisekelo inokumelana okungcono kwe-oxidation ephezulu yokushisa kanye nokushisa okuphezulu kwe-corrosion ukumelana.
3.Amandla omshini: Ama-alloys asekelwe ku-cobalt anamandla amahle kakhulu okushisa aphezulu kanye nokumelana nokukhathala okuhle kokushisa, kuyilapho ama-alloys asekelwe ku-nickel ane-ductility enhle kakhulu futhi ekwazi ukusetshenzwa, kodwa amandla awo okushisa aphezulu kanye nokumelana nokukhathala okushisayo kungaphansi kancane kune-alloys esekelwe ku-cobalt. . Ezingeni lokushisa lasekamelweni, amandla ama-alloys asekelwe ku-cobalt aphansi kancane, kodwa ukuphakama kukhulu; Ama-alloys asekelwe ku-nickel anamandla aphakeme, kodwa aphuka kakhudlwana, futhi kufanele asetshenziswe ngokuqapha ezindaweni ezinomthelela. Emazingeni okushisa aphezulu, lapho izinga lokushisa lingu-650°C, ama-alloys asekelwe ku-nickel anamandla aphakeme, kodwa futhi ayaphuka kakhulu, futhi ajwayele ukuphuka lapho esetshenziswa ezimweni ezithinta umthelela. Lapho izinga lokushisa likhuphukela ku-900 ° C, i-superalloy esekelwe ku-nickel ngeke isakwazi ukusetshenziswa, kuyilapho i-diamond-based superalloy isenamandla athile.
4.Ukuqina kwemishini: Okubizwa ngokuthi ukuqina yikhono lempahla yokumelana nokuguqulwa. Ukuqina kwama-alloys asekelwe ku-nickel kuphansi kunama-alloys asekelwe ku-cobalt kuwo wonke amazinga okushisa.
Uisihlakaniphi
Ama-alloys asekelwe ku-cobalt avame ukusetshenziselwa ukukhiqiza izingxenye ezihlukahlukene kanye nezingxenye ngaphansi kwezimo zokusebenza ezingagugi, ezimelana nokugqwala, izinga lokushisa eliphezulu kanye nezimo zokusebenza eziphikisana nomthelela; ama-alloys asekelwe ku-nickel asetshenziswa kakhulu kwezokundiza, i-aerospace, amandla, olwandle, ukuvikelwa kwemvelo kanye neminye imikhakha, ikakhulukazi Ukukhiqizwa kwezingxenye ezibalulekile ezifana nama-turbine blades kanye namakamelo omlilo ezinjini ze-aero.
