Vim muaj kev vam meej hauv kev sib raug zoo thiab kev tsim kho thev naus laus zis, kev lag luam koom nrog biomaterials tau nce thiab tseem loj hlob ntawm tus nqi nrawm.Titanium alloyyog cov khoom siv dav siv hauv kev kho mob, feem ntau raws li nws cov biocompatibility superior, siab zog, thiab corrosion kuj, thiab nws cov kev siv nyob rau hauv tib neeg lub cev muaj ntau haiv neeg.
Titanium thiab titanium alloy cov ntaub ntawv yog dav siv nyob rau hauv ntau yam kev lag luam xws li nuclear kev lag luam, tshuaj thiab petrochemical industries, aerospace, cov khoom ua si, kho hniav, thiab kho mob kho. Titanium alloy cov ntaub ntawv tseem raug xaiv raws li cov ntaub ntawv nyiam los hloov lossis kho cov ntaub so ntswg ua tsis tiav (cov ntaub ntawv siv biomedical) vim lawv cov khoom tshwj xeeb.
Kev siv ntawm titanium alloys
Artificial pob qij txha thiab orthopedic implants
Artificial pob qij txha (xws li, lub duav, lub hauv caug) thiab orthopedic implants (xws li, spinal fusion devices) ua los ntawm titanium alloys muaj biocompatibility zoo heev thiab durability, muab ib qho tseem ceeb kho cov cuab yeej rau cov neeg mob xav tau kev hloov los yog reconstruction.
Kev kho hniav kho hniav thiab implants
Hauv kev kho hniav, titanium alloys tau siv dav hauv kev tsim cov khoom cog thiab kho hniav kho hniav uas sib raug zoo nrog cov ntaub so ntswg los muab kev txhawb nqa thiab txhim khu kev qha.
Pacemakers thiab sab hauv stents
Titanium sab hauv stents yog siv nyob rau hauv vascular thiab plawv phais, xws li arterial stents thiab pacemakers, los pab cov neeg mob rov zoo li qub physiological muaj nuj nqi.
Kev kho mob-qib titanium alloys tsis yog tsuas yog tsis muaj tshuaj lom, hnav, thiab muaj lub zog-rau-hnyav piv, tab sis lawv kuj pom zoo biocompatibility thiab corrosion kuj. Cov khoom no ua rau lawv zoo tagnrho rau kev siv hauv kev kho mob cog thiab lwm yam kev siv hauv tib neeg lub cev. Tsis tas li ntawd, titanium cov peev txheej muaj ntau nyob rau hauv lub ntiaj teb crust, qhia tias muaj peev xwm tseem ceeb rau kev txhim kho ntxiv. Yog li ntawd, titanium sawv ua ib qho zoo tagnrho thiab cog lus biomaterial nyob rau hauv lub tshav pob ntawm biomedical engineering nrog dav daim ntawv thov prospects.
Tam sim no, ntshiab titanium (xws li TA1 thiab TA2; TA1 hais txog titanium nrog purity ntau dua 99.6%, thaum titanium nrog purity qis dua 99.6% yog hu ua TA2), Ti-6Al-4 V, Ti-5Al-2.5Fe, Ti-6Al{14}}Nb alloys yog siv dav hauv kev kho mob. Txawm li cas los xij, cov titanium alloys tshiab tau dhau los ua cov ntsiab lus kub hauv kev tshawb fawb vim lawv cov biocompatibility zoo dua thiab kev sib raug zoo txhua yam. Cov alloys no suav hais tias yog cov cuab yeej zoo tshaj plaws hauv kev kho mob cog.
Nyob rau hauv lub neej yav tom ntej, ntau lawm technology ntawm titanium alloys yuav mus txuas ntxiv mus rau qis modulus thiab siab zog. Xav txog cov qauv kev loj hlob, -type titanium alloys xav tias yuav tshwm sim raws li kev taw qhia rau kev nce qib yav tom ntej thiab muaj peev xwm dhau los ua "tus thawj coj" hauv kev kho mob titanium alloy kev lag luam.
