Puas yog Titanium Rust?
Tsis yog - titanium tsis xeb raws li cov hlau lossis hlau ua. Xeb yog cov hlau oxide flaky uas tsim thaum hlau reacts nrog oxygen thiab dej. Titanium tsis muaj hlau, yog li nws tsis tuaj yeem tsim xeb. Hloov chaw, nws txhim kho nyias, pom tsis pom thiab ruaj khov heevtitanium dioxide (TiO₂) passive zaj duab xisuas blocks ntxiv corrosion.
Yuav ua li cas Passive Film Ua Haujlwm
TiO₂ zaj duab xis, tsuas yog hais txog 2-5 nanometers tuab, cov ntaub ntawv tam sim ntawd raug rau huab cua lossis dej thiab muaj peb qhov kev txiav txim siab zoo:
Kev ruaj ntseg heev- nws tiv thaiv tshuaj tua kab mob thoob plaws pH dav heev.
Tus kheej- kho- yog khawb los yog puas, zaj duab xis rov- cov ntaub ntawv nyob rau hauv vib nas this nyob rau hauv muaj oxygen los yog noo noo.
Adherent- tsis zoo li xeb, nws tsis flake tawm; nws nyob ruaj khov rau cov hlau thiab tiv thaiv oxidation ntxiv.
Qhov no yog vim li cas titanium tseem nyob ruaj khov nyob rau hauv cov dej qab ntsev, cov huab cua sov huab cua thiab ntau xyoo dhau los ntawm sab nraum zoov, thiab yog vim li cas nws thiaj li siv rau hauv cov platforms offshore, cov nroj tsuag desalination thiab cov khoom hauv nkoj.
Titanium nyob rau hauv dej hiav txwv thiab huab cua
Titanium yog ib qho ntawm cov tshuaj chloride tshaj plaws - tiv taus engineering hlau. Hauv cov dej hiav txwv, txawm tias qhov kub siab, cov qib ntshiab hauv kev lag luam qhia qhov tsis zoo ntawm corrosion, ua titanium cov khoom xaiv rau seawater heat exchangers, condenser tubes thiab marine hardware. Los nag, av noo thiab condensation tsis muaj qhov ua tau zoo ntawm cov yeeb yaj kiab passive.
Dab tsi Corrosion tuaj yeem Titanium tseem raug?
Corrosion ntawm titanium yog ua tau, tab sis nws yog nyob rau hauv lub zos thiab yuav tsum tau txhoj puab heev tej yam kev mob:
Kev txhim kho corrosion- nyob rau hauv nruj, oxygen-depleted qhov khoob (flange ntsej muag, hauv qab gaskets, fouled deposits) ntawm qhov kub thiab txias nyob rau hauv concentrated chloride tov.
Pitting- tsawg, thiab feem ntau txuam nrog oxidizing chlorides hauv crevice-zoo li geometry.
Kev ntxhov siab -corrosion tawg- muaj peev xwm nyob rau hauv ib puag ncig tshwj xeeb (xws li, kub anhydrous methanol, liab fuming nitric acid, qee cov chlorides ntawm qhov kub thiab txias nyob rau hauv siab).
Cov kev ua tsis tiav no yog qhov tshwj xeeb, tsis yog tus cwj pwm kev pabcuam ib txwm muaj, thiab txhua tus tuaj yeem tswj hwm los ntawm kev xaiv qib, tsim qauv (tsis txhob muaj crevices) lossis qhov chaw.
Qib-los ntawm-Qib Qhia Kev Xaiv
| Qib | Kev sib xyaw | Corrosion Cim | Hom kev siv |
|---|---|---|---|
| Gr1–Gr4 | Kev lag luam ntshiab Ti | Zoo heev general & seawater kuj; lub zog nce nrog qib | Chemical hlab ntsha, marine, tshav kub exchangers |
| Gr5 (Ti-6Al-4V) | Alpha{0}}beta alloy | Kev ua haujlwm zoo; qis dua qib ntshiab hauv qee qhov kev tshaj tawm | Aerospace, siab -cov qauv muaj zog |
| Gr7/Gr11 | CP Ti + 0.12–0.25% Pd | Resistant txo cov acids (HCl, H₂SO₄) qhov twg ntshiab Ti tsis | Kev ua tshuaj lom neeg, kev pabcuam acid |
| Gr9 (Ti-3Al-2.5V) | Alpha-beta, tsis tshua muaj hlau | Zoo corrosion nrog ntau zog | Hydraulic tubing, cov khoom ua si |
| Gr 12 | CP Ti + Mo + Ni | Txhim kho kev tiv thaiv hauv kev txo / oxidizing media | Chemical, geothermal, marine |
FAQ
Q1: Puas yuav titanium xeb hauv dej ntsev lossis los nag?
Tsis yog. TiO₂ zaj duab xis ua kom titanium ruaj khov hauv dej hiav txwv, los nag thiab cov av noo siab.
Q2: Yuav ua li cas yog tias titanium raug khawb?
Tsis muaj xeb daim ntawv - oxide zaj duab xis nws tus kheej- kho tsis pub dhau vib nas this hauv huab cua lossis dej.
Q3: Puas yog titanium corrosion tag nrho- pov thawj?
Tsis nyob rau hauv txhua qhov chaw: nyob rau hauv huab cua txias (kub concentrated chlorides nyob rau hauv crevices, muaj zog txo acids, tej yam kub chemicals) localized corrosion yog ua tau. Kev xaiv qib daws feem ntau ntawm cov xwm txheej no.
Q4: Titanium vs stainless hlau?
Titanium feem ntau tiv taus ntau dua li stainless hlau hauv chloride- nplua nuj thiab marine ib puag ncig, thiab tiv thaiv lub pitting thiab kev ntxhov siab -corrosion uas 304/316 tuaj yeem raug kev txom nyem hauv dej hiav txwv.
