Hais txog kev tshawb fawb txog biomedical cov ntaub ntawvGr.5 kho mob titaniumTam sim no, Tuam Tshoj thiab txawv teb chaws feem ntau tsom los txhim kho cov yam ntxwv ua haujlwm xws li bioactivity, biocompatibility, thiab hnav tsis kam ntawm Ti6Al4V nto, uas feem ntau ua tiav los ntawm kev npaj cov yeeb yaj kiab ua haujlwm thiab txheej txheej ntawm nws qhov chaw.
Ua ntej, peb tuaj qhia zaj duab xis.
Txheej txheej ntawm TiO2 zaj duab xis nyob rau saum npoo ntawm Ti alloy tuaj yeem txhim kho nws cov bioactivity, tab sis nws yog ib qho teeb meem uas cov thickness ntawm zaj duab xis tsis zoo li qub thiab lub zog sib txuas tsis siab. Li Kewen npaj graphene txheej rauGr.5 kho mob titaniumnto los ntawm zaj duab xis hloov txoj kev nrog kev pab los ntawm graphene conductive zaj duab xis. Nws tau pom tias cov graphene txheej muaj kev sib raug zoo nrog cov matrix, nce hydrophilicity thiab deg roughness, thiab txhim kho bioactivity thiab biocompatibility, tab sis cov khoom siv kho tshuab tsis hloov. Kev npaj ntawm graphene coatings rau saum npoo ntawm titanium alloy Ti6Al4V tau txais kev saib xyuas thiab kev siv nyob rau hauv xyoo tas los no, tab sis qhov zoo thiab cov nyhuv ntawm nws cov coatings yog heev cuam tshuam los ntawm cov txheej txheem graphene npaj, thiab tej yam kev npaj yuav ua rau cov tiam ntawm cytotoxicity. . Piv txwv li, graphene npaj los ntawm cov tshuaj vapor deposition yuav ua rau kom tus nqi ntawm neuronal apoptosis thiab ua rau kom qhov tshwm sim ntawm reactive oxygen hom (ROS) tshwm sim nyob rau hauv neuronal hlwb.
Wufanbuick bhakti et al. Siv plasma-enhanced chemical vapor deposition (PECVD) thev naus laus zis los npaj pob zeb diamond zoo li carbon films rauGr.5 kho mob titaniumQhov chaw nrog sib txawv roughness, Tsis tas li ntawd, kev tshawb fawb txog kev sib txuas ntawm daim nyias nyias, corrosion, thiab biocompatibility tau ua, Cov yeeb yaj kiab zoo li pob zeb diamond muaj qhov sib txuas siab tshaj plaws nrog cov substrate mus txog 45 N, Corrosion resistance, biocompatibility tau txhim kho, Kev npaj. ntawm pob zeb diamond zoo li zaj duab xis ntawm Ti6Al4V nto yog txoj kev hloov kho qhov chaw zoo.
Fabrication ntawm pob zeb diamond-zoo li zaj duab xis txheej rau saum npoo ntawm titanium alloy txawm hais tias qhov kev kho mob zoo tau ua tiav, pob zeb diamond zoo li tsis zoo rau hnav poob, yooj yim rau cov khib nyiab thiab tsim cov thrombus.
Hais txog nws txoj kev kawm txheej, thov ua raws li peb cov xov xwm tshiab kawg.
