Mechanical Properties And Composition Of Medical Titanium Qws TC4

Kev kho mob titanium pas nrig TC4 titanium alloy yog cov khoom siv kho mob uas muaj cov khoom siv zoo thiab biocompatibility. Nws muaj pes tsawg leeg yog tsim los ntawm titanium (Ti), txhuas (Al), hlau (Fe) thiab zinc (Zn), uas titanium tso nyiaj rau cov feem ntau tshaj, txog 90%. Cov ntsiab lus txhuas feem ntau yog 5.5% txog 6.75%, cov ntsiab lus hlau yog li ntawm 0.3%, thiab cov ntsiab lus zinc yog li 0.2%.
Kev taw qhia txog cov khoom xyaw:
1. Titanium (Ti): Titanium yog ib lub teeb yuag hlau nrog zoo heev biocompatibility thiab corrosion kuj. Raws li cov khoom siv kho mob, titanium yog dav soj ntsuam rau orthopedic implants, xws li pob txha daim hlau, ntsia hlau, thiab cov pob qij txha.
2. Aluminium (aluminium, Al): Qhov sib ntxiv ntawm aluminium tsub kom lub zog ntawm cov alloy. Cov ntsiab lus aluminium tsim nyog tuaj yeem kho cov khoom siv ntawm titanium alloys, ua rau lawv tsim nyog rau cov khoom siv kho mob
3. Vanadium (Vanadium, V): Lub xub ntiag ntawm vanadium txhim khu lub zog thiab corrosion kuj ntawm titanium alloys. Vanadium nyob rau hauv titanium alloys kuj pab txhim kho lawv cov cua sov kho.
TC4 titanium alloy muaj cov cuab yeej zoo heev, uas tau qhia tshwj xeeb hauv cov hauv qab no:
1. Lub zog siab: Lub zog tensile ntawm TC4 titanium alloy tuaj yeem ncav cuag ntau dua 1100 MPa, uas yog ib qho ntawm cov khoom siv muaj zog.
2. Zoo ductility: TC4 titanium alloy muaj cov yas zoo thiab ductility, thiab tuaj yeem deform mus rau ib qho twg thaum lub sij hawm stretching txheej txheem tsis muaj cracking.
3. Kev tiv thaiv corrosion zoo heev: TC4 titanium alloy muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem siv tau ntev ntev hauv qhov chaw hnyav xws li kua qaub thiab alkali, thiab tsis ua rau corrosion thiab oxidation.
4. Lub teeb yuag thiab lub zog siab: Piv nrog rau lwm cov ntaub ntawv hlau, TC4 titanium alloy muaj qhov ntom ntom, li 4.5 g / cm³, thaum tuav lub zog siab, yog li nws tau siv dav hauv kev kho mob.
Nrog nws cov khoom siv zoo heev thiab biocompatibility, kev kho mob titanium pas nrig TC4 tau raug soj ntsuam dav hauv kev tsim cov khoom cog orthopedic thiab tau dhau los ua cov khoom tseem ceeb rau kev txhawb nqa thiab kho lub cev pob txha.
Feem ntau, kev kho mob titanium pas nrig TC4 titanium alloy muaj cov khoom siv zoo heev thiab cov khoom muaj pes tsawg leeg, thiab tsim nyog siv rau hauv kev tsim cov khoom siv kho mob, cov pob qij txha, cov hniav cog hniav thiab lwm yam kev kho mob.
