Titanium Metal: Kupayona Innovations muBiomedical Applications

Mumunda wakawedzera webiomedicine, titanium simbi yakagara ichiita basa rakakosha, nekuda kwekusiyana kwayo kwemuviri nemakemikari zvimiro. Pakati peanonyanya kushandiswa titanium alloys, Ti-6Al-4V uye Ti-6Al-4V ELI yakambotonga sekuenda-kune zvinhu zvekurapa. Nekudaro, sezvo tsvakiridzo yave kufambira mberi, kushushikana kwakabuda pamusoro penjodzi dzehutano dzinounzwa neiyo vanadium chinhu mune aya alloys. Kunyangwe pasina masangano anodzora akarambidza zviri pamutemo kushandiswa kwayo, kushandiswa kweTi-6Al-4V alloys mubiomedical sector kwakaona kuderera kunooneka.

Mukupindura kune izvi zvinonetsa, zvikwata zvekutsvagisa pasi rose zvakatanga kugadzirwa kwetitanium alloys matsva ekushandiswa kwekurapa. Masayendisiti muSwitzerland akaita budiriro yekutanga nekugadzira iyo Ti-6Al-7Nb alloy, iyo yakashandiswa zvinobudirira mumakiriniki marongero. KuChina, kubatana pakati peBeijing Nonferrous Metals Research Institute neBaoji Nonferrous Metals Processing Plant kwakatungamira mukugadzirwa kwevanadium-isina yekurapa titanium alloy. Hutsva uhu hwakapfuura miedzo yakaoma yekiriniki uye yakapihwa Mubairo wekutanga weSainzi neTechnological Progress muNonferrous Metals neChina muna 2001, zvichiratidza kubudirira kwakakosha mumunda wezvekurapa titanium alloys.

Zvisingafaniri kupera, zvikwata zvekutsvaga kubva kunyika dzakaita seGermany neIndia zvakafambirawo mberi zvakanyanya, zvichiunza mishonga mitsva yetitanium alloys yakadai seTi-5Al-2.5Fe, Ti-5Al-1.5B, uye Ti-15Mo-5Zr-3Al. Kufambira mberi uku hakuna kungowedzera huwandu hwezvinhu zviripo mubiomedicine asi zvakare zvakapa varwere nzira dzakasiyana dzekurapa.

Sezvo zvinodiwa zvekuwedzera kwebiocompatibility, vaongorori vari kutarisisa zvakanyanya kukanganiswa kwealloying zvinhu pamuviri wemunhu. Zvidzidzo kubva kuma1990 zvakaratidza kuti aruminiyamu, chinhu chinowanikwa mutitanium alloys, inogona kukanganisa hurongwa hwetsinga uye yakabatanidzwa nechirwere cheAlzheimer. Nekuda kweizvozvo, kuvandudzwa kweasina-chepfu, biocompatible titanium alloys yave yakakosha.

Tichifunga nezvezviwanikwa izvi, vaongorori vanobva kunyika dzakaita seUnited States neJapan vakatungamira mukugadzira ma<em>β-titanium alloys matsva, achibatanidza zvinhu zvisina muchetura zvakaita semolybdenum, niobium, tantalum, uye zirconium. Aya ma alloys haangope yakanakisa biocompatibility asi zvakare anoratidza yakadzika elastic modulus, iyo inowirirana zvakanyanya neiyo yegobvu remunhu. Kufanana uku kunowedzera kugadzikana uye kunyaradza kwemishonga inodyara.

Mukupedzisa, titanium simbi iri kuita shanduko yakakosha mune yayo biomedical application. Nekuenderera mberi kwekubuda kwemishonga mitsva yetitanium alloys uye kufambira mberi mune tekinoroji, zviri pachena kuti titanium ichaita basa rakatonyanya kukosha mune ramangwana rebiomedicine, ichibatsira zvakanyanya mukuvandudzwa kwehutano hwevanhu.
