Ti-6Al-4V ELI titanium bar yog tsim tshwj xeeb thiab siv rau kev tsim cov khoom cog rau kev kho mob.
Nws yog suav tias yog "tus qauv kub" ntawm cov titanium alloys kho mob. Nws lub ntsiab lus tseem ceeb yog tswj lub zog siab thiab kev sib raug zoo ntawm cov titanium alloys thaum txhim kho qhov tawv thiab kev ntseeg siab mus sij hawm ntev los ntawm kev tswj hwm cov khoom sib xyaw ua ke.
Nws Yog Dab Tsi?–Lub ntsiab lus ntawm "ELI"
Ti-6Al-4V ELISCov qauv rau Extra Low Interstitial Ti-6Al-4V alloy, thoob ntiaj teb hu ua Titanium Qib 23 kom paub qhov txawv ntawm cov titanium Qib 5 ib txwm muaj. Qhov sib txawv tseem ceeb ntawm Ti-6Al-4V ELI (Qib 23) thiab cov Ti-6Al-4V ib txwm muaj (Qib 5) yog raws li nram no:
Cov Khoom Tseem Ceeb thiab Cov Txiaj Ntsig
Qhov "extra low interstitial" microstructure no muab ntau qhov zoo tseem ceeb rau kev siv kho mob:
Kev Nyuaj Siab Rau Kev Pob Txha Thiab Kev Qaug Zog: Cov pa oxygen, hlau, thiab lwm yam khoom uas raug tswj hwm nruj heev tiv thaiv kev tsim cov khoom sib xyaw ua ke. Qhov no ua rau cov khoom muaj peev xwm tiv taus kev qaug zog ntawm kev tawg hauv qab kev ntxhov siab ntawm lub cev tib neeg (piv txwv li, kev thauj khoom thaum taug kev)—ib qho tseem ceeb rau kev cog hniav mus sij hawm ntev.
Kev sib raug zoo ntawm Biocompatibility thiab Corrosion Resistance: Txais titanium qhov tsis muaj tshuaj lom rau tib neeg cov ntaub so ntswg, cov hlau no tsim cov txheej oxide ruaj khov ntawm nws qhov chaw uas yuav luag tsis xeb hauv cov kua dej hauv lub cev, nrog rau cov hlau ion tso tawm tsawg heev, ua kom muaj kev nyab xeeb mus sij hawm ntev.
Cov Khoom Siv Kho Tshuab Txhim Khu Kev: Nrog lub zog tensile feem ntau tshaj 860MPa thiab elongation tshaj 10%, nws muab lub zog txaus rau cov ntawv thov thauj khoom xws li lub duav thiab pob txha caj qaum thaum khaws cia kom txaus ductility.
Cov Ntawv Thov Ib Txwm Muaj: Siv Qhov Twg Hauv Lub Cev?
Ua ib yam khoom siv cog rau hauv lub cev uas ua raws li ASTM F136, nws yog siv dav los tsim ntau yam khoom cog rau hauv lub cev uas muaj zog heev:
Cov Pob Qij Txha Loj Uas Muaj Peev Xwm Thauj Khoom: Cov ceg cuav ntawm lub duav, cov khoom hloov pauv hauv caug, thiab lwm yam, uas nyiaj tau kev ntxhov siab ntev thiab xav tau lub zog qaug zog heev.
Cov Txheej Txheem Kho Pob Txha: Cov cages sib txuas pob txha, cov pedicle screw-rod systems, thiab lwm yam, siv los tswj thiab txhawb nqa pob txha caj qaum.
Kev Siv Rau Kev Raug Mob Thiab Kev Kho Hniav: Cov phaj pob txha muaj zog heev, cov ntsia hlau pob txha, thiab cov hniav cog.
