Izinzuzo ze-titanium njengento yokufakelwa kwamathambo

Izinzuzo ze-titanium njengento yokufakelwa kwamathambo ibonakala ikakhulukazi kulezi zici ezilandelayo:

1.I-Biocompatibility:

I-Titanium inokuvumelana okuhle kwezicubu zomuntu, ukusabela okuncane kwebhayoloji nomzimba womuntu, ayinabo ubuthi futhi ayiwona uzibuthe, futhi ayinayo imiphumela emibi enobuthi emzimbeni womuntu.

Lokhu kuvumelana okuhle kwe-biocompatibility kuvumela izimila ze-titanium ukuthi zibe khona emzimbeni womuntu isikhathi eside ngaphandle kokubangela ukusabela okusobala kokulahlwa.

2. Izakhiwo zikaMechanical:

I-Titanium inezici zamandla aphezulu kanye ne-modulus enwebekayo ephansi, engagcini nje ngokuhlangabezana nezidingo zemishini, kodwa futhi iseduze ne-elastic modulus yethambo lomuntu wemvelo.

Le mpahla yemishini isiza ukunciphisa umphumela wokuvikela ukucindezeleka futhi isiza kakhulu ekukhuleni nasekuphulukisweni kwamathambo abantu.

I-elastic modulus yei-titanium alloyiphansi. Isibonelo, i-elastic modulus ye-titanium emsulwa ingu-108500MPa, eseduze nethambo lemvelo lomzimba womuntu,

kusiza ekumisweni kwamathambo futhi kunciphise umphumela wokuvikela ukucindezeleka kwamathambo kuzimila.

3. Ukumelana nokugqwala:

Ingxubevange ye-Titanium iyinto engasebenzi kahle ngokwebhayoloji enokumelana nokugqwala okuhle endaweni yemvelo yomzimba womuntu.

Lokhu kumelana nokugqwala kuqinisekisa ukuzinza kwesikhathi eside kwe-titanium alloy implants emzimbeni womuntu futhi ngeke kungcolise imvelo yemvelo yomzimba womuntu ngenxa yokugqwala.

4.Isisindo esingasindi:

Ubuningi be-titanium alloy buphansi uma kuqhathaniswa, kuphela u-57% wensimbi engagqwali.

Ngemva kokufakwa emzimbeni womuntu, kunganciphisa kakhulu umthwalo emzimbeni womuntu, okubaluleke kakhulu ezigulini ezidinga ukugqoka izimila isikhathi eside.

5, Non-magnetic:

Ingxubevange ye-Titanium ayiwona uzibuthe futhi ayithinteki izinkambu zikazibuthe kanye nokuduma kwezulu, okuzuzisa ukuphepha komzimba womuntu ngemva kokufakwa.

6, Ukuhlanganiswa okuhle kwamathambo:

Ungqimba lwe-oxide olwakhiwe ngokwemvelo ebusweni be-titanium alloy lunomthelela ekuveleni kokuhlanganiswa kwamathambo futhi luthuthukise ukunamathela phakathi kokufakelwa kanye nethambo.

Sethula izinto ezimbili ezifaneleke kakhulu ze-titanium alloy:

Ukusebenza kwe-TC4:

Ingxubevange ye-TC4 iqukethe u-6% no-4% we-vanadium. Iyingxubevange yohlobo lwe-α+β esetshenziswa kakhulu kakhulu enomphumela omkhulu kakhulu. Inamandla aphakathi nendawo kanye nepulasitiki efanelekile. Isetshenziswa kabanzi ku-aerospace, izindiza, izimila zomuntu (amathambo okufakelwa, amalunga e-hip yabantu kanye nezinye izinto eziphilayo, ama-80% awo okwamanje asebenzisa le alloy), njll. Imikhiqizo yayo eyinhloko imigoqo namakhekhe.

I-Ti6AL7Nbukusebenza

Ingxubevange ye-Ti6AL7Nb iqukethe u-6% AL no-7% Nb. Yizinto eziphambili kakhulu ze-titanium alloy ezakhiwe futhi zasetshenziswa ekufakweni komuntu eSwitzerland. Igwema ukushiyeka kwamanye ama-alloys okufakelwa futhi idlala kangcono indima ye-titanium alloy ku-ergonomics. Iyinto ethembisa kakhulu yokufakelwa komuntu esikhathini esizayo. Izosetshenziswa kabanzi ekufakweni kwamazinyo e-titanium, ukufakwa kwamathambo omuntu, njll.

Kafushane, i-titanium njengento yokufakelwa kwamathambo inezinzuzo ze-biocompatibility enhle kakhulu, izakhiwo zemishini, ukumelana nokugqwala, isisindo esilula, okungewona uzibuthe kanye nokuhlanganiswa okuhle kwamathambo, okwenza i-titanium ibe ukukhetha okuhle kwezinto zokufakelwa kwamathambo.
