1. Zoo heev corrosion kuj
Lub dullness ntawm titanium nyob ntawm seb muaj cov oxide zaj duab xis, thiab nws cov corrosion kuj zoo dua nyob rau hauv oxidizing media dua li hauv kev txo cov xov xwm, qhov twg muaj corrosion kuj yuav tshwm sim. Titanium tsis corroded nyob rau hauv ib co corrosive media, xws li seawater, ntub chlorine, chlorite thiab hypochlorite tov, nitric acid, chromic acid, hlau chloride, sulfide, thiab organic acids. Txawm li cas los xij, titanium feem ntau muaj tus nqi siab corrosion hauv xov xwm (xws li hydrochloric acid thiab sulfuric acid) uas cuam tshuam nrog nws los tsim hydrogen. Tab sis ntxiv me me ntawm oxidant rau cov kua qaub ua rau cov titanium tsim ib zaj duab xis passivation. Yog li titanium yog resistant rau corrosion nyob rau hauv ib tug sib tov ntawm sulfuric acid rau nitric acid los yog hydrochloric acid rau nitric acid, txawm nyob rau hauv hydrochloric acid muaj dawb chlorine. Kev tiv thaiv oxide zaj duab xis ntawm titanium feem ntau yog tsim thaum cov hlau kov dej, txawm tias me me los yog muaj dej vapor. Yog tias titanium raug rau ib puag ncig oxidizing heev thaum tsis muaj dej, oxidation ceev thiab hnyav, feem ntau tshwm sim tshwm sim tshwm sim. Cov cwj pwm zoo li no tau tshwm sim nrog cov tshuaj tiv thaiv ntawm titanium nrog fuming nitric acid uas muaj ntau tshaj nitrogen oxide thiab nrog cov roj chlorine qhuav. Txawm li cas los xij, txhawm rau tiv thaiv cov tshuaj tiv thaiv zoo li no, yuav tsum muaj qee qhov dej.
2. Kev ua haujlwm kub zoo
Feem ntau, txhuas ntawm 150 degree, stainless hlau ntawm 310 degree uas poob nws cov khoom qub siab, thiab titanium alloy ntawm txog 500 degree tseem tuav cov khoom zoo. Thaum lub dav hlau ceev nce mus txog 2.7 npaug ntawm qhov ceev ntawm lub suab thiab qhov kub thiab txias ntawm lub dav hlau mechanism mus txog 230 degree, aluminium alloy thiab magnesium alloy tsis tuaj yeem siv, thaum titanium alloy tuaj yeem ua tau raws li qhov yuav tsum tau ua. Titanium muaj cua sov zoo thiab tsim nyog rau turbine discs thiab cov hniav ntawm aero-engine compressors thiab daim tawv nqaij ntawm lub rear fuselage ntawm aircraft.
3, Kev ua haujlwm kub qis yog qhov zoo
Lub zog ntawm qee cov titanium alloys (xws li Ti-5Al-2.5Sneli) nce nrog qhov kub thiab txias, tab sis cov yas txo qis me ntsis. Nws tseem muaj qhov zoo ductility thiab toughness ntawm qis kub, uas yog haum rau siv nyob rau hauv ultra-tsawg kub. Yuav siv tau rau hauv cov kua hydrogen, kua oxygen foob pob ua ntxaij cav, los yog nyob rau hauv manned spacecraft los ua ultra-tsawg kub ntim thiab cia tso tsheb hlau luam.
4, tsis muaj hlau nplaum
Titanium yog non-magnetic, nws yog siv nyob rau hauv submarine vaj tse, thiab tsis ua rau kuv tawg.
5, Tsawg damping kev ua haujlwm
Siv titanium thiab lwm yam khoom siv hlau (tooj liab, hlau) ua kom cov duab thiab qhov loj ntawm lub tswb raws nraim tib yam, nrog tib lub zog los khob txhua lub tswb yuav pom tias lub tswb ua los ntawm titanium vibration tuaj lub suab ntev, uas. yog, los ntawm kev tawm tsam lub zog muab rau lub tswb tsis yooj yim kom ploj mus.
6. Lub cim xeeb muaj nuj nqi
Ti-50 feem pua Ni (atomic fraction) alloy, nyob rau hauv qee qhov kub thiab txias, muaj peev xwm los kho nws cov duab qub, yog li nws hu ua titanium zoo nco alloy.
7. Superconductivity
NbTi alloy, thaum kub poob mus rau zero kiag li, NbTi alloy ua los ntawm hlau, yuav poob tsis kam, yuav ua tau ib tug loj tam sim no los ntawm, cov hlau yuav tsis kub, tsis muaj zog noj, yog li NbTi alloy yog hu ua superconducting khoom.
8. Hydrogen absorption muaj nuj nqi
Ti-50 feem pua Fe (atomic feem) alloy, nrog loj nqus ntawm hydrogen. Siv cov yam ntxwv ntawm Ti-Fe alloy, hydrogen tuaj yeem khaws cia kom nyab xeeb, uas yog, nws tsis tas yuav tsum siv lub tog raj kheej siab siab rau hydrogen cia. Qee qhov xwm txheej tseem tuaj yeem tso cov hydrogen cia Ti-Fe alloy hydrogen tawm, yog li nws yog hu ua hydrogen cia khoom.
