Qhov zoo ntawm titanium raws li cov khoom siv cog orthopedic

Qhov zoo ntawm titanium raws li cov khoom cog orthopedic feem ntau yog tshwm sim hauv cov hauv qab no:

1, Biocompatibility:

Titanium muaj biocompatibility zoo nrog tib neeg cov ntaub so ntswg, cov tshuaj lom neeg tsawg tsawg nrog tib neeg lub cev, tsis muaj tshuaj lom thiab tsis muaj hlau nplaum, thiab tsis muaj tshuaj lom rau tib neeg lub cev.

Qhov zoo biocompatibility no tso cai rau titanium implants kom muaj nyob rau hauv tib neeg lub cev rau lub sij hawm ntev yam tsis ua kom pom tseeb tsis pom zoo tshwm sim.

2, Mechanical Properties:

Titanium muaj cov yam ntxwv ntawm lub zog siab thiab tsis tshua muaj elastic modulus, uas tsis tsuas yog ua tau raws li cov kev xav tau ntawm txhua yam, tab sis kuj yog nyob ze rau cov elastic modulus ntawm tib neeg cov pob txha.

Cov cuab yeej siv tshuab no pab txo cov kev ntxhov siab tiv thaiv thiab ua kom muaj kev loj hlob thiab kho cov pob txha ntawm tib neeg.

Lub elastic modulus ntawmtitanium alloyqis. Piv txwv li, lub elastic modulus ntawm ntshiab titanium yog 108500MPa, uas yog ze rau lub ntuj pob txha ntawm tib neeg lub cev, uas yog.

conducive rau pob txha teeb thiab txo cov kev ntxhov siab shielding nyhuv ntawm cov pob txha ntawm implants.

3, Corrosion kuj:

Titanium alloy yog cov khoom siv tsis muaj roj ntsha uas muaj kev tiv thaiv corrosion zoo nyob rau hauv ib puag ncig physiological ntawm tib neeg lub cev.

Qhov kev tiv thaiv corrosion no ua kom muaj kev ruaj ntseg ntev ntawm titanium alloy implants nyob rau hauv tib neeg lub cev thiab yuav tsis ua phem rau lub physiological ib puag ncig ntawm tib neeg lub cev vim corrosion.

4 、 Lub teeb yuag:

Qhov ntom ntawm titanium alloy yog qhov tsawg, tsuas yog 57% ntawm cov hlau tsis muaj steel.

Tom qab cog rau hauv tib neeg lub cev, nws tuaj yeem txo qhov load ntawm tib neeg lub cev, uas yog qhov tseem ceeb tshwj xeeb rau cov neeg mob uas yuav tsum tau hnav cov khoom cog rau lub sijhawm ntev.

5, Tsis-magnetic:

Titanium alloy tsis yog hlau nplaum thiab tsis cuam tshuam los ntawm electromagnetic teb thiab thunderstorms, uas muaj txiaj ntsig zoo rau kev nyab xeeb ntawm tib neeg lub cev tom qab cog.

6, Cov pob txha zoo:

Lub ntuj tsim oxide txheej nyob rau saum npoo ntawm titanium alloy pab rau qhov tshwm sim ntawm cov pob txha kev koom ua ke thiab txhim kho cov adhesion ntawm cov cog thiab cov pob txha.

Taw qhia ob qhov zoo tshaj plaws titanium alloy cov ntaub ntawv:

TC4 kev ua haujlwm:

TC4 alloy muaj 6% thiab 4% vanadium. Nws yog feem ntau siv α + β hom alloy nrog cov zis ntau tshaj plaws. Nws muaj lub zog nruab nrab thiab haum plasticity. Nws yog dav siv nyob rau hauv aerospace, aviation, tib neeg implants (cov pob txha pob txha, tib neeg lub duav pob qij txha thiab lwm yam biomaterials, 80% ntawm uas tam sim no siv no alloy), thiab lwm yam. Nws cov khoom tseem ceeb yog tuav thiab ncuav.

Ti6AL7 Nbkev ua tau zoo

Ti6AL7Nb alloy muaj 6% AL thiab 7% Nb. Nws yog cov khoom siv zoo tshaj plaws titanium alloy tsim thiab siv rau tib neeg cog hauv Switzerland. Nws zam qhov tsis txaus ntawm lwm cov khoom cog cog thiab zoo dua ua lub luag haujlwm ntawm titanium alloy hauv ergonomics. Nws yog cov khoom cog qoob loo zoo tshaj plaws rau tib neeg yav tom ntej. Nws yuav siv dav hauv kev cog hniav titanium, tib neeg cov pob txha cog, thiab lwm yam.

Hauv cov ntsiab lus, titanium ua cov khoom cog orthopedic muaj qhov zoo ntawm biocompatibility zoo heev, txhua yam khoom, corrosion kuj, lub teeb yuag, tsis sib nqus thiab cov pob txha zoo, uas ua rau titanium yog qhov kev xaiv zoo tshaj plaws rau cov khoom cog orthopedic.
