Izinto eziluncedo ze-titanium njengesixhobo sokufakelwa kwamathambo

Uncedo lwe-titanium njengesixhobo sofakelo lwamathambo lubonakaliswa ikakhulu kule miba ilandelayo:

1, Ukuhambelana kwebhayoloji:

I-Titanium ine-biocompatibility efanelekileyo kunye nezicubu zomntu, ukusabela okuncinci kwebhayoloji kunye nomzimba womntu, ayinayo ityhefu kwaye ayinamagnetic, kwaye ayinazo iziphumo ezibi emzimbeni womntu.

Le biocompatibility ilungileyo ivumela ukufakelwa kwe-titanium ukuba kubekho emzimbeni womntu ixesha elide ngaphandle kokubangela ukusabela okucacileyo kokwaliwa.

2. Iipropati zoomatshini:

I-Titanium ineempawu zamandla aphezulu kunye ne-elastic modulus ephantsi, engaphumeleliyo kuphela kwiimfuno zoomatshini, kodwa ikufutshane ne-elastic modulus yethambo lomntu wendalo.

Le propati yomatshini inceda ukunciphisa umphumo wokukhusela uxinzelelo kwaye ilungele ukukhula kunye nokuphulukiswa kwamathambo abantu.

Imodyuli elastiki yeingxubevange titaniumiphantsi. Umzekelo, i-elastic modulus ye-titanium ecocekileyo yi-108500MPa, ekufutshane nethambo lendalo lomzimba womntu,

inceda ukuseta amathambo kunye nokunciphisa uxinzelelo lokhuseleko lwesiphumo samathambo kwizihlunu.

3. Ukuchasa ukuMhlwa:

Ingxubevange ye-Titanium sisixhobo esingasebenziyo sebhayoloji esinokumelana ne-corrosion elungileyo kwindawo yendalo yomzimba womntu.

Oku kuxhathisa i-corrosion kuqinisekisa ukuzinza kwexesha elide lokufakelwa kwe-titanium alloy emzimbeni womntu kwaye akuyi kungcolisa indawo ye-physiological yomzimba womntu ngenxa yokubola.

4.Ikhaphukhaphu:

Ubuninzi be-titanium alloy buphantsi kakhulu, kuphela yi-57% yensimbi engenasici.

Emva kokufakwa emzimbeni womntu, kunokunciphisa kakhulu umthwalo kumzimba womntu, obaluleke kakhulu kwizigulane ezifuna ukugqoka iimplants ixesha elide.

5, Non-magnetic:

I-Titanium alloy ayinamagnetic kwaye ayichatshazelwa ngamasimi e-electromagnetic kunye neendudumo, eziluncedo kukhuseleko lomzimba womntu emva kokufakelwa.

6, Ukudityaniswa kwamathambo okulungileyo:

Umaleko we-oxide owenziwe ngokwemvelo kumphezulu we-titanium alloy unegalelo ekuveleni kokuhlanganiswa kwamathambo kunye nokuphucula ukunamathela phakathi kokufakelwa kunye nethambo.

Ukwazisa izinto ezimbini ezifanelekileyo ze-titanium alloy:

Ukusebenza kwe-TC4:

I-alloy ye-TC4 iqulethe i-6% kunye ne-4% ye-vanadium. Yeyona isetyenziswa kakhulu i-alpha yodidi lwe-α+β enemveliso enkulu. Inamandla aphakathi kunye neplastiki efanelekileyo. Isetyenziswa ngokubanzi kwi-aerospace, i-aviation, implants yabantu (amathambo okufakelwa, ama-hip joints kunye nezinye izinto eziphilayo, i-80% yazo ngoku zisebenzisa le alloy), njl. Iimveliso zayo eziphambili yimivalo kunye namaqebelengwane.

I-Ti6AL7Nbukusebenza

I-alloy ye-Ti6AL7Nb iqulethe i-6% AL kunye ne-7% Nb. Yeyona nto iphambili ye-titanium alloy imathiriyeli ephuhliswe yaza yasetyenziswa kukufakelwa kwabantu eSwitzerland. Ithintela ukusilela kwezinye ii-alloys zokufakelwa kwaye idlala ngcono indima ye-titanium alloy kwi-ergonomics. Yeyona nto ithembisayo yokufakelwa komntu kwixesha elizayo. Kuya kusetyenziswa ngokubanzi kwi-titanium implants yamazinyo, ukufakelwa kwamathambo omntu, njl.

Isishwankathelo, i-titanium njengesixhobo sokufakelwa kwe-orthopedic ineenzuzo ze-biocompatibility egqwesileyo, iipropathi ze-mechanical, ukumelana nokugqwala, ubunzima obulula, ubuchwephesha obungenamagnetic kunye nokudibanisa kakuhle kwamathambo, okwenza i-titanium ibe yinto efanelekileyo yokukhetha izinto zokufakelwa kwamathambo.
