Titanium yog ib qho khoom siv ntau heev. Lub purity ntawm daim txhuam cev titanium tuaj yeem ncav cuag 99.9%. Titanium alloy cov khoom muaj lub cev thiab tshuaj lom neeg ruaj khov, thiab yuav tsis nqus los ntawm tib neeg lub cev. Lawv yuav tsis muaj tshuaj lom neeg nrog rau cov kua hauv lub cev thiab tshuaj, thiab lawv yuav tsis ionize, thiab lawv yuav tsis hnov tsw nrog tib neeg musculoskeletal cov leeg. Yog li ntawd, lawv hu ua "biophilic metals".
Vim tias titanium yog "bio-phooj ywg", titanium nyob rau hauv tib neeg lub cev tuaj yeem tiv thaiv corrosion ntawm secretions thiab tsis muaj tshuaj lom. Nws yog haum rau txhua txoj kev ua kom tsis muaj menyuam. Yog li ntawd, nws yog siv dav hauv kev tsim cov cuab yeej kho mob, suav nrog tib neeg lub hauv siab pob qij txha, lub hauv caug sib koom, lub xub pwg sib koom tes, flank sib koom tes, pob txha taub hau, lub plawv valve thiab pob txha fixation clip.
Biomedical titanium alloy cov ntaub ntawv yog ib hom kev ua haujlwm cov ntaub ntawv siv hauv biomedical engineering. Lawv tsuas yog siv rau hauv kev tsim thiab tsim cov khoom siv phais, cov cuab yeej orthopedic thiab lwm yam khoom.
Raws li cov txheej txheem kev phais thiab cov khoom siv orthopedic, titanium alloy cov ntaub ntawv tuaj yeem muab faib ua "cov ntaub ntawv hlau" hauv "cov khoom siv rau kev cog hniav", thaum titanium alloy cov ntaub ntawv tuaj yeem siv los ua cov hlab plawv, pob txha thiab pob txha, pob txha. sib koom ua ke, txha nraub qaum, cov cuab yeej orthopedic, cardiac pacemakers thiab defibrillators, cochlear implants Raw khoom rau paj stimulators thiab lwm yam khoom cog.
Biomedical titanium alloys tuaj yeem muab faib ua Hom titanium alloy (xws li ntshiab titanium series) + Hom titanium alloy (xws li Ti6Al4V, thiab lwm yam) thiab Piv nrog kev kho mob stainless hlau thiab cobalt raws li alloys, Ti-type titanium alloys (xws li ti12mo6zr2fe ) thiab TiNi cov duab nco titanium alloys muaj cov yam ntxwv ntawm lub ntiajteb txawj nqus me me, lub zog tshwj xeeb, Tsawg elastic modulus, corrosion kuj, dawb txiav thiab zoo biocompatibility.
