Vim kev vam meej ntawm tib neeg thiab kev loj hlob ntawm kev siv tshuab, kev ua lag luam sib koom ntawm cov khoom siv roj ntsha tau ntau dua thiab nws tseem loj hlob ntawm qhov ceev ceev. Cov ntaub so ntswg hloov cov ntaub ntawv nyuaj, xws li cov hniav cuav, cov pob qij txha, thiab cov pob txha pob txha, suav nrog kev nce qib hauv kev kho mob biomaterials thiab loj hlob sai.
Titanium thiab titanium alloycov khoom siv dav siv hauv kev lag luam nuclear, tshuaj lom neeg thiab petrochemical kev lag luam, aerospace, khoom ua si, kho hniav thiab kho mob, thiab lwm yam. Titanium alloy cov ntaub ntawv kuj raug xaiv los ua cov khoom siv zoo tshaj plaws los hloov lossis kho cov ntaub so ntswg ua tsis tiav (cov ntaub ntawv siv biomedical qauv).
Cov hlau ntshiab titanium muaj kev tiv thaiv corrosion zoo, tab sis nws cov biocompatibility thiab cov khoom siv txhua yam tsis zoo, nws lub zog yog qhov tsawg thiab nws cov nqi tsim khoom kuj kim heev. Qhov tshwm sim ntawm titanium alloy tuaj yeem hloov tau zoo rau nws.
Piv nrog stainless hlau, muaj ntshiab (CP) Nb, Cr-Co alloy, thiab cp-Ta cov ntaub ntawv rau kev siv kho mob, titanium alloy tuaj yeem ua tau raws li qhov yuav tsum tau ua, vim yog tsim cov txheej txheem oxidation ntawm nws qhov chaw, ua rau zoo heev. corrosion kuj thiab tsis tshua muaj elastic modulus.
Kev kho mob titanium alloy, tsis muaj tshuaj lom, lub teeb yuag, thiab lub zog tshwj xeeb, tsis tsuas yog muaj biocompatibility zoo heev thiab corrosion kuj thiab tuaj yeem siv los ua cov cog cog thiab lwm yam, nws yog cov khoom siv kho mob zoo tshaj plaws, thiab titanium hauv lub ntiaj teb crust. nplua nuj nyob rau hauv reserves, muaj peev xwm txhim kho ntxiv, yog qhov zoo tshaj plaws thiab daim ntawv thov kev cia siab ntawm biomedical engineering cov ntaub ntawv.
Tam sim no, ntshiab titanium (TA1, TA2; TA1 yog titanium ntshiab ntau dua 99.6 feem pua ntawm titanium, ntshiab titanium purity tsawg dua 99.6 yog TA2) thiab Ti-6Al-4V, Ti{{10} }Al-2.5Fe, Ti-6Al-7Nb alloys tau siv dav hauv kev kho mob. Txawm li cas los xij, titanium alloy tshiab tau dhau los ua qhov kev tshawb fawb tsom ntawm kev kho mob tshiab titanium alloy nrog zoo biocompatibility thiab mechanical compatibility, uas yog lub peev xwm tshaj plaws hauv kev kho mob cog.
Nyob rau hauv lub neej yav tom ntej, ntau lawm technology ntawm titanium alloy tseem yuav tsim nyob rau hauv cov kev taw qhia ntawm tsawg modulus thiab siab zog. Los ntawm qhov kev xav ntawm kev txhim kho tiam sis, titanium alloy yuav dhau los ua cov kev taw qhia ntawm kev txhim kho yav tom ntej thiab "tus thawj coj" ntawm kev kho mob titanium alloy kev lag luam.
Tam sim no, cov kws tshawb fawb Suav tau tsim cov khoom siv kho hniav Ti-Zr alloy los ntawm kev xa mus rau cov khoom siv ntawm Co-Cr alloy thiab hom IV alloy feem ntau siv hauv cov chaw kho mob, uas xav tias yuav dhau los ua titanium alloy tshiab rau kev kho hniav. Tsis tas li ntawd, TAMZ (Ti-Al-Mo-Zr, thiab lwm yam) kev kho mob alloy tau tsim los ntawm peb lub teb chaws, uas muaj kev sib raug zoo dua thiab tus nqi qis thiab tsim nyog rau kev kho hniav braces thiab clings.
Kuv ntseeg hais tias nrog kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, Suav kev tshawb fawb ntawm titanium alloy yuav ua rau qhov tob thiab meej.
