Biomedical titanium alloy: Classification, Performance

Biomedical titanium alloys tuaj yeem raug cais raws li cov qauv ntawm cov khoom siv. Hom, ntxiv rau Hom, thiab Titanium alloy hom III. Tam sim no, ntshiab titanium thiab Ti-6Al-4V alloy tseem siv dav hauv kev kho mob. tab sis Titanium-hom alloys tau dhau los ua cov ntsiab lus kev tshawb fawb kub hauv daim teb no vim lawv qhov qis elastic modulus thiab zoo biocompatibility. Nws yog qhov zoo tshaj plaws biomedical titanium alloy.

Table 1 qhia cov khoom siv kho tshuab ntawm ntau yam biomedical titanium alloys. Daim duab 1 qhia txog kev sib piv ntawm elastic modulus ntawm ntau yam biomedical alloys nrog cov pob txha ntawm tib neeg. Raws li koj tau pom, Lub elastic modulus ntawm lub thib ob tiam biomedical titanium yog ho qis dua li ntawm thawj tiam. Muaj kev nce ntxiv hauv Nb cov ntsiab lus hauv kev tsim alloy thiab ob qho tib si yog Titanium alloy hom, Ti-35Nb-7Zr-5Ta thiab Ti-29Nb-13 Ta-7.1Zr alloys muaj qhov qis tshaj elastic modulus ntawm 55MPa, uas yog qhov ze tshaj plaws ntawm tib neeg cov pob txha. Yog li ntawd, txoj kev loj hlob ntawm biomedical cov ntaub ntawv uas tsis tshua muaj elastic modulus Ti-type alloy tau dhau los ua kev tshawb fawb hotspot nyob rau hauv daim teb no. Biomedical hyperelasticity, feem ntau tau kawm nyob rau hauv tsev thiab txawv teb chaws Titanium alloy yog ti NB hyperelastic Titanium alloy.
