Titanium yog cov khoom siv tshuaj lom neeg nrog cov cim tshuaj Ti thiab tus lej atomic 22. Nws yog cov xim dawb-dawb hloov pauv hlau uas muaj lub teeb yuag, lub zog siab, nws yog xim hlau, thiab zoo corrosion kuj (xws li seawater, aqua regia, thiab lwm yam) thiab chlorine). . Vim nws cov khoom siv ruaj khov, zoo kub tsis kam, tsis kub tsis kam, muaj zog acid tsis kam, muaj zog alkali tsis kam, siab zog thiab tsawg ntom, nws yog hu ua "qhov chaw hlau". Titanium tau tshawb pom los ntawm Gregor hauv Cornwall, England hauv xyoo 1791, thiab tau muaj npe tom qab Titan ntawm Greek mythology los ntawm Klaproth. Titanium muaj ntau yam kev siv hauv kev kho mob.
Titanium yog ze rau tib neeg cov pob txha, muaj biocompatibility zoo rau tib neeg cov ntaub so ntswg, thiab tsis muaj tshuaj lom thiab phiv. Tib neeg implants yog cov khoom siv tshwj xeeb uas muaj feem xyuam nrog tib neeg lub neej thiab kev noj qab haus huv. Piv nrog rau lwm cov ntaub ntawv hlau, qhov zoo ntawm kev siv cov pob titanium thiab titanium alloys pob yog raws li hauv qab no:
1. Lub teeb yuag
2. Tsawg elastic modulus
3. Tsis muaj hlau nplaum
4. Tsis muaj tshuaj lom
5. Corrosion kuj
6. Lub zog muaj zog thiab zoo toughness Tus nqi ntawm titanium alloy siv rau hauv kev phais implants yog loj hlob ntawm tus nqi ntawm 5 feem pua -7 feem pua ib xyoo. Femoral lub taub hau, lub duav sib koom, humerus, pob txha taub hau, hauv caug sib koom tes, lub luj tshib, lub xub pwg sib koom, metacarpophalangeal sib koom, lub puab tsaig pob txha, lub plawv daim nyias nyias, lub raum daim nyias nyias, vascular dilator, splint, prosthesis, Pua pua ntawm cov hlau qhov chaw xws li fastening screws tau muab tso rau hauv. tib neeg lub cev, thiab cov txiaj ntsig zoo tau ua tiav, uas tau txais kev qhuas los ntawm cov neeg kho mob.
