Melemo ea titanium joalo ka ntho e kenngoeng ka masapo e bonahala haholo ka lintlha tse latelang:
1, Biocompatibility:
Titanium e na le biocompatibility e ntle le lisele tsa motho, karabelo e fokolang ea tlhaho le 'mele oa motho, ha e chefo ebile ha e na makenete, ebile ha e na litlamorao tse chefo' meleng oa motho.
Biocompatibility ena e ntle e lumella li-implants tsa titanium ho ba teng 'meleng oa motho nako e telele ntle le ho baka maikutlo a hlakileng a ho hana.
2. Thepa ea mochini:
Titanium e na le litšoaneleho tsa matla a phahameng le modulus e tlase ea elastic, e sa finyelleng litlhoko tsa mochini feela, empa hape e haufi le modulus ea elastic ea lesapo la tlhaho la motho.
Thepa ena ea mochine e thusa ho fokotsa phello ea ho thibela khatello ea kelello 'me e thusa ho hōla le ho folisa masapo a batho.
The elastic modulus eamotsoako oa titaniume tlase. Mohlala, modulus elastic ea titanium e hloekileng ke 108500MPa, e haufi le lesapo la tlhaho la 'mele oa motho,
e thusa ho beha masapo le ho fokotsa khatello ea maikutlo ea masapo ho li-implants.
3. Corrosion resistance:
Titanium alloy ke thepa e sa sebetseng ea biologically e nang le khanyetso e ntle ea kutu tikolohong ea 'mele oa motho.
Khanyetso ena ea kutu e tiisa botsitso ba nako e telele ba li-implants tsa alloy ea titanium 'meleng oa motho' me e ke ke ea silafatsa tikoloho ea 'mele oa motho ka lebaka la ho bola.
4. E bobebe:
Boima ba alloy ea titanium bo tlase haholo, ke 57% feela ea tšepe e sa hloekang.
Ka mor'a ho kenngoa 'meleng oa motho, e ka fokotsa haholo mojaro' meleng oa motho, e leng oa bohlokoa haholo ho bakuli ba hlokang ho apara li-implants nako e telele.
5, Non-magnetic:
Titanium alloy ha e na makenete ebile ha e angoe ke masimo a motlakase le lialuma, tse molemo bakeng sa polokeho ea 'mele oa motho kamora ho kenngoa.
6, Khokahano e ntle ea masapo:
Lera la oxide le entsoeng ka tlhaho holim'a alloy ea titanium le kenya letsoho hore ho be le ho kopana ha masapo le ho ntlafatsa ho khomarela pakeng tsa ho kenngoa le lesapo.
E hlahisa lisebelisoa tse peli tse loketseng tsa alloy ea titanium:
Ts'ebetso ea TC4:
TC4 alloy e na le 6% le 4% vanadium. Ke motsoako o sebelisoang haholo oa mofuta oa α+β o nang le tlhahiso e kholo ka ho fetisisa. E na le matla a mahareng le polasetiki e loketseng. E sebelisoa haholo sebakeng sa lifofane, lifofane, li-implants tsa batho (masapo a maiketsetso, manonyeletso a letheka la motho le lintho tse ling tse phelang, 80% ea tsona hona joale li sebelisang motsoako ona), joalo-joalo Lihlahisoa tsa eona tse ka sehloohong ke li-bar le likuku.
Ti6AL7Nbtshebetso
Ti6AL7Nb alloy e na le 6% AL le 7% Nb. Ke lisebelisoa tse tsoetseng pele ka ho fetisisa tsa titanium alloy tse entsoeng le ho sebelisoa ho li-implants tsa batho Switzerland. E qoba mefokolo ea li-alloys tse ling tse kentsoeng 'me e bapala karolo e ntle ea alloy ea titanium ho ergonomics. Ke ntho e tšepisang ka ho fetisisa e kentsoeng ke motho nakong e tlang. E tla sebelisoa haholo ho kenngoa ha meno ea titanium, ho kenngoa ha masapo a motho, joalo-joalo.
Ka kakaretso, titanium e le ntho e kenngoeng ka masapo e na le melemo ea biocompatibility e ntle haholo, thepa ea mochini, ho hanyetsa kutu, boima bo bobebe, ho se sebetse ha makenete le ho kopanya hantle ha masapo, e leng se etsang hore titanium e be khetho e nepahetseng bakeng sa lisebelisoa tsa ho kenya masapo.
