Tshiab nyob rau hauv xyoo tas los Tshiab Tsim -Type Biomedical Titanium Alloy, xws li Ti Nb, Ti-Mo, Ti Zr, thiab Ti TA alloys, feem ntau yog siv rau hauv kev kho mob cog. (V, Al, Ni, Cr, thiab lwm yam khoom tsim kev puas tsuaj rau tib neeg lub cev yog maj mam hloov los ntawm cov khoom tsis muaj tshuaj lom xws li Nb, Zr, Ta, Sn, Pt, thiab Mo nrog biocompatibility zoo) qee qhov kev kho mob qis dua hom titanium alloy yog qhia nyob rau hauv daim duab hauv qab no. Piv nrog rau -Type, Ti NB alloys muaj qis dua elastic modulus, uas yog ze rau lub elastic modulus ntawm tib neeg cov pob txha, thiab tsis muaj cov tshuaj lom Al thiab V. lawv haum rau cov khoom siv kho mob hlau. Tam sim no, ntau hom kev tshawb fawb tau ua rau lawv.

Daim ntawv thov
Biomedical titanium alloy muaj cov khoom siv kho mob zoo heev, uas ua rau nws siv dav hauv qab no:
Kev txhim kho yav tom ntej ntawm biomedical titanium alloys
Nyob rau hauv xyoo tsis ntev los no, daim ntawv thov ntawm titanium alloys nyob rau hauv lub biomedical teb yog tsim sai heev, uas tseem yuav muab rau pem hauv ntej ntau dua yuav tsum tau rau kev ua tau zoo ntawm titanium alloys. Ua ke nrog cov kev tshawb fawb tam sim no hauv tsev thiab txawv teb chaws, nws tau txiav txim siab tias yav tom ntej txoj kev loj hlob ntawm biomedical titanium alloys yog raws li hauv qab no:
1. Tshiab hom B titanium alloy yog cov kev tshawb fawb hotspot thiab lub ntsiab kev taw qhia ntawm biomedical titanium alloy cov ntaub ntawv nyob rau hauv lub ntiaj teb no.
2. Ib leeg siv lead ua biomedical titanium alloy. Cov khoom siv lead ua ib leeg loj hlob raws ib qho kev taw qhia tuaj yeem tau txais ib qho elastic modulus ze rau ntawm tib neeg cov pob txha. Lub implant ua los ntawm no ib leeg siv lead ua muaj zoo modulus txuam.
3. Biomedical ntxeem tau titanium alloy khoom, uas nws elastic modulus tuaj yeem dhau los ntawm lub qhov, qhov kev hloov ntawm porosity yog kho kom txo, tab sis lub zog yog txo. Yog li ntawd, yuav ua li cas los txhim kho nws cov cuab yeej cuab tam yog kev tshawb fawb kev taw qhia.
4. Biomedical titanium alloy nrog super elasticity thiab zoo lub cim xeeb muaj nuj nqi.
5. Kev hloov kho saum npoo ntawm cov ntaub ntawv biomedical tuaj yeem txhim kho biocompatibility ntawm cov cog cog.
