Taw qhia
Ferrotitanium, tseem hu ua titanium hlau los yog FeTi, yog ib qho alloy ntawm titanium thiab hlau. Nws yog feem ntau siv nyob rau hauv kev tsim cov hlau thiab lwm yam alloys vim nws cov ntsiab lus titanium siab, uas imparts zoo heev zog thiab corrosion kuj rau cov khoom kawg. Ib yam li cov hlau, thaum raug cov pa atmospheric, ferrotitanium yuav hnov mob thiab tsim ib txheej oxide rau ntawm qhov chaw. Cov txheej oxide no feem ntau hu ua xeb hauv cov hlau, tab sis puas yog ferrotitanium xeb tib yam?
Rust yog dab tsi?
Ua ntej peb tuaj yeem teb cov lus nug ntawm seb puas yog ferrotitanium xeb, peb yuav tsum tau txhais tias peb txhais li cas los ntawm xeb. Rust yog ib lo lus siv los piav txog oxidation ntawm hlau thiab nws cov alloys. Cov tshuaj tiv thaiv uas tshwm sim thaum lub sij hawm xeb yog redox cov tshuaj tiv thaiv ntawm hlau thiab oxygen. Cov hlau ua oxidized los ua hlau oxide (Fe2O3), uas yog cov khoom siv xim liab-xim av feem ntau hu ua xeb.
Hlau rusts yooj yim nyob rau hauv lub xub ntiag ntawm oxygen thiab noo noo vim hais tias cov tshuaj tiv thaiv yog catalyzed los ntawm dej. Cov dej reacts nrog hlau los tsim hydrated hlau oxide (Fe2O3•xH2O), uas yog cov khoom xoob thiab ntxeem tau. Raws li cov txheej txheem xeb txuas ntxiv, cov hlau hydrated oxide yuav flakes, nthuav tawm cov hlau tshiab kom ntxiv oxidation.
Ferrotitanium thiab Rust
Tam sim no peb nkag siab tias xeb yog dab tsi, peb tuaj yeem kuaj xyuas seb puas yog ferrotitanium xeb. Raws li tau hais dhau los, ferrotitanium yog ib qho alloy ntawm titanium thiab hlau. Titanium yog cov hlau uas muaj zog heev uas tsim cov txheej txheem oxide tiv thaiv ntawm nws qhov chaw thaum raug huab cua. Cov txheej oxide no ruaj khov thiab tiv thaiv cov hlau hauv qab los ntawm oxidation ntxiv.
Nyob rau hauv cov ntaub ntawv ntawm ferrotitanium, titanium cov ntsiab lus yog siab txaus los tsim ib tug tiv thaiv oxide txheej nyob rau saum npoo ntawm lub alloy. Cov oxide txheej no yog tsim los ntawm titanium dioxide (TiO2), uas yog cov khoom siv tawv thiab ruaj khov uas tiv taus corrosion heev. Yog li ntawd, ferrotitanium tsis xeb zoo ib yam li cov hlau ua.
Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias ferrotitanium tsis tiv thaiv corrosion. Sij hawm dhau mus, cov txheej txheem tiv thaiv oxide nyob rau saum npoo ntawm cov hlau tuaj yeem raug puas los yog degraded los ntawm kev raug mob hnyav, xws li cov dej ntsev los yog cov kua qaub. Thaum qhov no tshwm sim, cov hlau hauv qab tuaj yeem raug oxidation thiab corrosion.
Txhawm rau txo qhov kev pheej hmoo ntawm corrosion hauv ferrotitanium, nws yog ib qho tseem ceeb uas yuav tsum tau khaws cia thiab tuav cov khoom kom zoo. Ferrotitanium yuav tsum tau khaws cia kom qhuav thiab deb ntawm cov dej noo, thiab yuav tsum tau muab cia rau hauv qhov chaw uas muaj qhov cua zoo los tiv thaiv kev tsim cov pa phem. Tsis tas li ntawd, ferrotitanium yuav tsum tau ua tib zoo saib xyuas kom tsis txhob khawb thiab lwm yam kev puas tsuaj saum npoo uas tuaj yeem cuam tshuam kev ncaj ncees ntawm cov txheej txheem oxide tiv thaiv.
Xaus
Hauv kev xaus, ferrotitanium tsis xeb tib yam li cov hlau ua vim nws cov ntsiab lus titanium siab, uas tsim cov txheej txheem ruaj khov thiab tiv thaiv oxide txheej ntawm cov hlau. Txawm li cas los xij, ferrotitanium tseem muaj kev cuam tshuam rau corrosion nyob rau hauv qee qhov chaw thiab tej yam kev mob, thiab kev cia thiab tuav kom zoo yog qhov tseem ceeb los txo qhov kev pheej hmoo ntawm corrosion.
