Cov ntaub ntawv rau orthopedic implants feem ntau yog hlau, xws li stainless hlau, cobalt thiab nws cov alloys, titanium thiab nws alloys, thiab lwm yam. Ntawm cov no, titanium alloys tau siv dav hauv kev kho mob vim lawv cov biocompatibility zoo, siab zog, corrosion kuj, thiab tsawg ntom. Nyob rau hauv xyoo tas los no, ntau tus kws tshawb fawb tau ua nyob rau hauv - kev tshawb fawb tob txog ntau yam ntawm titanium alloy ua txoj kev, kev hloov kho saum npoo, qhov pore loj, thiab porosity, aiming los daws teeb meem xws li siab elastic modulus, deg inertness, thiab hlau ion tso tawm uas titanium alloys ntsib nyob rau hauv kev kho mob daim ntawv thov. Cov kev tshawb fawb no tsis tsuas yog pab txhim kho cov kev siv tshuaj lom neeg ntawm titanium alloys tab sis kuj txhim kho hauv vivo pob txha kev ua tau zoo, tshuaj tua kab mob, thiab kev nyab xeeb.
Txij li thaum xyoo 1960, titanium alloys tau siv los ua cov khoom cog. Txij thaum ntawd los, cov kws tshawb fawb tau kawm txog kev hloov pauv ntawm cov alloy muaj pes tsawg leeg thiab cov yam ntxwv saum npoo los tsim cov khoom siv nrog kev pom zoo ntawm cov khoom siv kho tshuab thiab tshuaj lom neeg. Ntau yam txheej txheem niaj hnub ua, nrog rau cov txheej txheem tsim nyog thiab kev hloov kho, yuav tsum ua kom tiav qhov kev ua tau zoo ntawm titanium implants. Xav tau ntau cov peev txheej thiab kev tshawb fawb los tsim kom muaj qhov tawv, biocompatible, corrosion-resistant, thiab hnav-resistant titanium alloy.
Los ntawm kev nkag siab txog ntau yam ntawm titanium alloys, cov kev daws teeb meem sib txawv tau raug npaj los daws cov teeb meem xws li siab elastic modulus thiab deg inertness. Kev hloov kho deg thiab kev kho saum npoo yog feem ntau siv txoj hauv kev los ua kom muaj kev ua haujlwm ntawm titanium alloys. Kev tsim cov ntxeem tau ntawm titanium alloys tsis tsuas yog hais txog qhov teeb meem ntawm qhov siab elastic modulus tab sis kuj txhim kho kev ua haujlwm lom neeg hauv cov pob txha. Txawm li cas los xij, tseem muaj ntau yam teeb meem uas yuav tsum tau sib tham thiab daws hauv kev tsim cov txheej txheem ntawm ntau yam ntxeem tau titanium alloys. Kev siv cov txheej txheem ua haujlwm nrog cov qauv ntxeem tau thiab kev tshawb pom ntawm cov qauv biomimetic ntawm cov pob txha trabeculae muab cov kev xaiv zoo dua rau kev nce qib ntawm titanium alloy kev siv tshuaj lom neeg. Nyob rau hauv lub neej yav tom ntej, peb vam tias yuav txuas ntxiv txhim kho daim ntawv thov ntawm cov khoom siv roj ntsha ntawm cov titanium alloys thaum txhim kho cov khoom siv kho tshuab thiab ua tiav cov kev nce qib tshiab thiab kev tshawb pom hauv kev txhim kho cov pob txha hauv zos, kev sib koom ua ke ntawm cov pob txha, cov khoom tiv thaiv kab mob, thiab kev tiv thaiv kab mob.
