Chii chinonzi Ti-6Al-4V ELI Titanium Bar uye Nei Ichishandiswa Pakuisirwa Mishonga?

Ti-6Al-4V ELI titanium bar yakagadzirwa uye inoshandiswa pakugadzira ma implants ekurapa.

Inonyanya kuonekwa se "chiyero chegoridhe" pakati pema "titanium alloys" ekurapa. Kukosha kwayo kukuru kuri mukuchengetedza simba rakawanda uye kubatana kwakanaka kwe "titanium alloys" ukuwo ichivandudza zvakanyanya kusimba uye kuvimbika kwenguva refu kuburikidza nekudzora kwakasimba kwezvikamu.

Chii ichochi?–Zvinoreva "ELI"

Ti-6Al-4V ELISZvishandiso zveExtra Low Interstitial Ti-6Al-4V alloy, inozivikanwa pasi rose seTitanium Grade 23 kuti isiyanise kubva kune titanium yeGiredhi 5. Musiyano mukuru uripo pakati peTi-6Al-4V ELI (Giredhi 23) neTi-6Al-4V yeGiredhi 5 ndewekuti:

Hunhu Hunokosha uye Zvakanakira

Iyi "extra low interstitial microstructure" inopa mabhenefiti akakosha ekushandisa mukurapa:

Kusimba Kwakanyanya Kwekutyoka uye Kuramba Kuneta: Mwero weokisijeni, iron, nezvimwe zvinhu zvinodzora zvakanyanya zvinodzivirira kuumbwa kwemakemikari asina kusimba. Izvi zvinoita kuti chinhu chacho chikwanise kukunda kuneta nekuneta pasi pekumanikidzwa kwakaoma kwemuviri wemunhu (semuenzaniso, mitoro panguva yekufamba)—chinhu chakakosha chinodiwa kuti pave nemidziyo inoiswa mumuviri kwenguva refu.

Kuenderana Kwakanaka Kwezvinhu Zvakafanana uye Kuramba Kuora: Ichigara nhaka kusakuvadza kwetitanium mumuviri wemunhu, chiumbwa ichi chinoumba ganda rakagadzikana re oxide pamusoro paro risingaori mumvura yemuviri, nekuburitswa kwemaion esimbi mashoma, zvichiita kuti rive rakachengeteka kwenguva refu.

Hunhu Hwakavimbika hweMichina: Nesimba rekudhonza rinowanzo pfuura 860MPa uye kureba kwe10%, rinopa simba rakakwana rekushandisa zvinotakura mutoro zvakaita semaimplant ehudyu nemusana uku richichengetedza ductility yakakwana.
