Kub siab tiv taus dej Cobalt pas nrig

Nws cov kub ua tsis taus feem ntau yog los ntawm cov khoom siv daws teeb meem thiab carbide phases zog, yog li tswj cov qauv txheej txheem ntawm cov khoom siv. Tsis tas li ntawd, ib tug tuab chromium oxide tiv thaiv zaj duab xis tuaj yeem tsim nyob rau saum npoo ntawm kev cobalt alloys, txuas ntxiv qhov siab} kub oxidation txheej txheem.

Lub ntsej muag tsis yooj yim ntawm qhov siab - cov khoom siv kub tsis txaus ntseeg nyob rau hauv lawv cov kev tsis sib haum xeeb ntawm kev kub ntxhov siab kawg, kev ntxhov siab, thiab ib puag ncig corrosive. Qhov nyiaj tshuav no nyuaj rau lwm cov ntaub ntawv kom ua tiav, tshwj xeeb hauv qab no:
1. Tshwj xeeb ua ke ntawm kev ua tau zoo heev - kub lub zog thiab cov enpees tiv thaiv kev ua tau zoo
Nov yog nws cov ntsiab lus zoo tshaj plaws. Tsis pub dhau qhov kub thiab txias ntawm 800℃c rau 1000℃c, lub zog ntawm kev cobalt alloys tau txo qis, thaum lub zog ntawm cobalt alloys nce mus txog nws lub ncov. Tseem ceeb tshaj, cobalt raws alloys muaj cov creep tsis zoo heev- Lub peev xwm tiv thaiv qeeb qeeb thiab kev ntxhov siab.
Irreplaceability: rau cov khoom siv kub kub xws li cov tshuab lim cua thiab cov lus qhia hauv lub dav hlau siv dav hlau, lawv yuav tsum ua haujlwm ntev nyob rau hauv high - pa yaig. Ib qho kev deormation me me tuaj yeem ua rau kev puas tsuaj loj. Ntawm no, cov txheej txheem ruaj khov thiab lub zog muab los ntawm high- cov khoom kub tsis tuaj yeem hloov pauv ntawm Nickel los yog cov khoom siv ceramic.
2. Kev tiv thaiv zoo heev rau cov kev qaug zog thiab cua sov poob siab
Ntau lub siab - cov khoom kub yuav tsum tau tiv thaiv cov cua sov uas muaj cua sov thiab ntau tiam thiab kev tshaj tawm ntawm kev ua haujlwm nkees sai. Cobalt raws li alloys muaj qhov qis coefficient ntawm thermal expansion thiab cov kev ua kom zoo, uas tuaj yeem tiv thaiv cov kev puas tsuaj no.
Irreplaceability: hauv high - race race rauv rollers, cov khoom siv ntau zaus muaj kev kub ntxhov ntau yam tshwm sim los ntawm kev pib nres. Cheebtsam ua los ntawm cov cob muaj zog muaj kev pab cuam ntev dua vim lawv muaj peev xwm tiv thaiv ntau dua cov khoom siv ceramic lossis qee yam nrog kev ua haujlwm tsis zoo.
3. Zoo tsis kam mus rau corrosion los ntawm ntau yam media thiab hnav tsis kam
Cobalt ua alloys tsis yog tiv thaiv siab {{0} Qhov tseem ceeb heev rau kev tawm tsam kub xws li sulfides thiab cov ntsev vag. Nyob rau tib lub sijhawm, nws cov kev kub ntxhov siab kuj coj tau cov kev hnav zoo tshaj plaws.
Irreplaceability: hauv cov petrochemical thiab lub zog teb, cov khoom siv roj feem ntau muaj cov neeg siv tub rog xws li, uas ua rau "kub siab" rau Nickel raws li alloys. Cobalt ua alloys yog qhov kev xaiv zoo dua rau kev cuam tshuam nrog ib qho chaw ib puag ncig zoo li no. Tsis tas li ntawd, rau cov khoom siv uas yuav tsum muaj kev txheeb ze, xws li cov rooj zaum valve, cov hnav tsis kam ua rau lawv tsis txaus ntseeg.
4. Irreplaceability piv rau lwm cov ntaub ntawv
Nickel raws Superalloys: Nickel raws li alloys muaj lub zog zoo hauv qab no Cobalt raws li alloys yog qhov kev xaiv txhim khu kev qha ntau dua thaum lub zog kub siab dua tshiab, xeb tsis kam, thiab thermal nkees kuj yuav tsum muaj ib txhij.
Cov ntaub ntawv muaj tej hub: ceramics muaj qhov kub siab dua, tab sis lawv cov kev txiav txim siab brittleness thiab tsis muaj kev hloov kho kom sov siab. Qhov nyuaj ntawm kev cobalt cov alloys tsis tuaj yeem piv rau Ceramics.
Refractory hlau (xws li tantalum thiab tungsten): tantalum thiab tungsten tau muaj siab heev ntawm cov neeg nqus dej siab, thiab lawv yuav tsum tau siv rau hauv lub tshuab nqus tsev. Cobalt raws li alloys tuaj yeem ua haujlwm stables ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig ntev thiab muaj cov ntau ntawm cov ntawv thov.

Lub irklaceability ntawm high - cov khoom siv kub tsis kam, tab sis los ntawm lawv cov kev sib tw zoo tshaj plaws, thermal corrosion ua hauj lwm, thiab hnav tsis kam. Thaum cov kev xav tau ntawm kev ntseeg tau muab tso rau cov khoom siv kub, thiab cov khoom siv kub siab "uas tau txheeb xyuas cov kev coj ua thiab tuaj yeem ntsib txhua yam mob uas xav tau. Qhov no yog qhov tseem ceeb vim li cas nws sawv ruaj khov hauv Aerospace, lub zog, thiab kev lag luam hnyav.
