Hauv kev xaiv cov khoom siv hauv kev lag luam, "Qhov twg zoo dua, nickel lossis tooj liab?" yog cov lus nug uas cov neeg siv khoom feem ntau nug. Txawm li cas los xij, qhov tseeb, tsis muaj qhov "zoo dua," tsuas yog "haum dua" - nickel zoo tshaj plaws hauv kev tiv thaiv xeb thiab kev tiv thaiv kub siab, thaum tooj liab muaj kev coj hluav taws xob zoo dua thiab kev siv nyiaj tsawg. Txhua tus ua si rau nws lub zog hauv ntau qhov xwm txheej sib txawv. Pib los ntawm cov khoom tseem ceeb, cov teb thov, thiab kev siv tiag tiag, tsab xov xwm no yuav pab koj piav qhia txog kev xaiv ntawm nickel thiab tooj liab, ua rau koj nrhiav tau cov khoom siv tsim nyog tshaj plaws rau koj cov kev xav tau.
Ua ntej, lub rooj hauv qab no muab kev sib piv meej ntawm cov khoom tseem ceeb thiab cov lus qhia kev hloov pauv ntawmnpib tsib(raws li peb cov khoom nickel ntshiab, nrog qhov huv ntawm ≥99.95%) thiabtooj liab(tooj liab ntshiab hauv kev lag luam, nrog qhov huv ntawm ≥99.9%):
| Kev Sib Piv Qhov Ntev | Nickel (Cov Khoom Siv Nickel Ntshiab) | Tooj Liab (Tooj Liab Ntshiab Hauv Kev Lag Luam) | Kev Hloov Kho Tseem Ceeb |
| Kev Ua Hluav Taws Xob | Kev coj ua: 22.1 × 10⁶ S/m | Kev coj ua: 58.5 × 10⁶ S/m (ze li ntawm 2.6x ntawm nickel) | Xaiv tooj liab rau cov xwm txheej conductive dav dav; xaiv nickel rau cov xwm txheej conductive uas xav tau ob qho tib si corrosion tsis kam / kub siab tsis kam |
| Kev Tiv Thaiv Kev Xeb | Tiv taus cov kua qaub, alkalis, thiab cov kua dej hauv lub cev (ua raws li ISO 10993 tus qauv), tsis muaj xeb tom qab 1000 teev ntawm kev nkag mus rau hauv dej hiav txwv | Yooj yim rau oxidation thiab patina tsim, tsis muaj zog acid/alkali tsis kam, tsuas yog haum rau qhuav/tsis muaj zog corrosive ib puag ncig | Xaiv nickel rau cov chaw muaj xeb (kev lag luam tshuaj lom neeg, kev kho mob, dej hiav txwv); xaiv tooj liab rau cov chaw qhuav, dav dav |
| Kev Tiv Thaiv Kub Siab | Melting point: 1455 ℃, kev pabcuam kub ntev txog li 1200 ℃ | Melting point: 1083 ℃, kev pabcuam kub ntev ≤300 ℃ | Xaiv nickel rau cov xwm txheej kub siab (cov khoom siv cua sov, aerospace); xaiv tooj liab rau cov xwm txheej kub qis/chav sov |
| Kev Kho Tshuab & Kev Ua Haujlwm | Zoo toughness kub tsawg (tuaj yeem khoov ntawm -200 ℃), tuaj yeem kos rau hauv cov xov hlau ultra-fine ntawm 0.05 hli | Zoo heev ductility, yooj yim rau stamp thiab khoov, tsawg ua nqi | Xaiv nickel rau qhov kub qis heev / cov lus qhia zoo heev; xaiv tooj liab rau kev tsim khoom nyuaj / kev xav tau pheej yig |
| Cov Qauv Khoom Ib Txwm Muaj | Hlau nickel ntshiab, nickel alloy strip, nickel ntawv ci | Tooj liab hlau, tooj liab busbar, tooj liab ntawv ci | Sib phim cov qauv khoom kom haum rau qhov xwm txheej xav tau; peb muab kev hloov kho rau cov hlau nickel/tooj liab-nickel |
Los ntawm qhov kev xav ntawm cov xwm txheej siv tau, qhov sib txawv ntawm kev xaiv ntawm ob qho no yog qhov meej dua:
Hauv kev siv hluav taws xob conductivity, tooj liab yog qhov nyiam rau cov xov hlau siv hauv tsev thiab cov xov hlau qis-voltage - nws ua tau raws li qhov xav tau conductivity yooj yim nrog nws cov conductivity siab thiab tus nqi qis. Txawm li cas los xij, nickel yog qhov yuav tsum muaj rau cov xov hlau sab hauv ntawm cov khoom siv kho mob (piv txwv li, cov xov hlau glucose pen probe) thiab cov xov hlau teeb liab ntawm cov cuab yeej aerospace: tus thawj xav tau kev tiv thaiv kev xeb ntawm cov kua dej hauv lub cev, thaum tus tom kawg xav tau kev tiv thaiv kub qis (qis dua -50 ℃ ntawm qhov siab). Peb cov xov hlau nickel ntshiab uas tau kho kom haum nrog kev kam rau siab ntawm 0.002 hli tau raug hloov kho los ntawm ntau lub tuam txhab kho mob / aerospace.
Hauv cov xwm txheej uas tiv taus xeb, nickel (tsis yog tooj liab) raug xaiv rau cov ntaub thaiv lub tank cia tshuaj thiab cov khoom siv sib txuas hauv hiav txwv: tooj liab xeb hauv ib hlis hauv dej ntsev lossis cov chaw acidic, thaum cov ntaub thaiv lub tank cia ua los ntawm peb cov phaj nickel ntshiab tseem tsis tau xau tom qab 3 xyoos siv hauv cov chaw lag luam tshuaj. Txawm li cas los xij, tooj liab muaj qhov zoo dua ntawm kev siv nyiaj txiag rau kev kho kom zoo nkauj hauv tsev thiab cov khoom siv sib txuas dav dav hauv cov chaw qhuav.
Hauv cov ntawv thov kub siab, tsuas yog nickel tuaj yeem siv rau cov khoom cua sov ntawm cov khoom siv cua sov thiab cov xov hlau ntawm cov pa tawm hauv tsheb: tooj liab mos thiab deforms ntawm qhov kub siab tshaj 500 ℃, thaum cov khoom cua sov ua los ntawm peb cov xov hlau nickel ntshiab tuaj yeem ua haujlwm ruaj khov ntawm 1200 ℃ hauv cov qhov cub kev lag luam rau ntau tshaj 5000 teev. Rau kev cua sov hauv chav tsev (piv txwv li, cov cua sov qis zog hauv cov khoom siv hauv tsev), tooj liab tuaj yeem xaiv los txo cov nqi.
Qhov tseem ceeb, thaum muaj xwm txheej xav tau "tooj liab lub conductivity + nickel lub corrosion resistance," peb cov khoom tooj liab-nickel alloy (piv txwv li, CuNi40) yog qhov kev daws teeb meem zoo tshaj plaws - lawv khaws cov tooj liab lub conductivity kom zoo dua (conductivity: 15 × 10⁶ S / m) thaum muaj nickel lub corrosion resistance (dej hiav txwv corrosion tsis kam ze li ntawm nickel ntshiab), thiab tau siv dav hauv cov cables marine thiab cov khoom siv dej hiav txwv desalination.
Hauv kev xaus lus, qhov tseem ceeb rau kev xaiv ntawm nickel thiab tooj liab yog nyob rau hauv "seb puas yuav tsum tau tiv taus corrosion, tiv taus kub siab, lossis tiv taus kub qis heev": yog tias xav tau cov khoom no, nickel yog qhov kev xaiv txhim khu kev qha dua; yog tias tsuas yog xav tau kev coj ua yooj yim, tus nqi qis, thiab kev ua tiav yooj yim, tooj liab yog qhov tsim nyog dua. Yog tias koj tseem tsis paub meej txog kev xaiv cov khoom siv, thov koj xav tiv tauj peb - peb tuaj yeem muab cov qauv tshwj xeeb ntawm nickel, tooj liab, thiab tooj liab-nickel alloys hauv 72 teev raws li koj cov xwm txheej (piv txwv li, kub, nruab nrab, kev coj ua),pab koj phim cov khoom siv kom raug.
