Njira yopangira utoto wa anodic ndi yofanana ndi ya electroplating, ndipo palibe zofunikira zapadera za electrolyte. Njira zosiyanasiyana zamadzimadzi za 10% sulfuric acid, 5% ammonium sulfate, 5% magnesium sulfate, 1% trisodium phosphate, etc., ngakhale njira yamadzi ya vinyo woyera ingagwiritsidwe ntchito pakufunika. Nthawi zambiri, njira yamadzi yosungunuka ya 3% -5% pa kulemera kwa trisodium phosphate ingagwiritsidwe ntchito. Popanga utoto kuti mupeze mtundu wamagetsi apamwamba, ma electrolyte sayenera kukhala ndi ayoni a chloride. Kutentha kwakukulu kumapangitsa kuti electrolyte iwonongeke ndikupangitsa filimu ya porous oxide, kotero electrolyte iyenera kuikidwa pamalo ozizira.
Mu utoto wa anode, dera la cathode lomwe limagwiritsidwa ntchito liyenera kukhala lofanana kapena lalikulu kuposa la anode. Kutsekeredwa kwapano ndikofunikira pakupanga utoto wa anodic, chifukwa ojambula nthawi zambiri amagulitsa ma cathodic apano molunjika ku clip yachitsulo ya burashi ya penti, pomwe malo opaka utoto ndi ochepa. Kuti mufanane ndi liwiro la anode reaction ndi kukula kwa elekitirodi ndi malo ojambulira, ndikuletsa filimu ya okusayidi kuti isaphwanyike komanso kuwonongeka kwamagetsi chifukwa chakuchulukirachulukira, mphamvu yapano iyenera kukhala yochepa.
Kugwiritsa ntchito ukadaulo wa anodizing mu zamankhwala azachipatala komanso makampani azamlengalenga
Titaniyamu ndi zinthu zopanda biologically inert, ndipo zimakhala ndi mavuto monga mphamvu zochepa zomangirira komanso nthawi yayitali ya machiritso pamene ikuphatikizidwa ndi fupa la mafupa, ndipo sikophweka kupanga osseointegration. Choncho, njira zosiyanasiyana ntchito padziko mankhwala a titaniyamu amadzala kulimbikitsa mafunsidwe HA pamwamba kapena kumapangitsanso adsorption wa biomolecules kusintha kwachilengedwenso ntchito. M'zaka khumi zapitazi, ma nanotubes a TiO2 adalandira chidwi chachikulu chifukwa cha zabwino zake. Kuyesa kwa in vitro ndi mu vivo kwatsimikizira kuti kungapangitse kuyika kwa hydroxyapatite (HA) pamwamba pake ndikuwonjezera mphamvu yolumikizana ndi mawonekedwe, potero kulimbikitsa kumamatira ndi kukula kwa osteoblasts pamtunda wake.
Common njira pamwamba mankhwala monga solgel wosanjikiza njira, hydrothermal mankhwala Electrochemical makutidwe ndi okosijeni ndi imodzi mwa njira yabwino kukonzekera kwambiri nthawi zonse anakonza TiO2 nanotubes. Mu kuyesera, zinthu kukonzekera TiO2 nanotubes ndi zotsatira za TiO2 nanotubes pa Chikoka cha mineralization ntchito ya titaniyamu pamwamba mu SBF njira.
Titaniyamu ili ndi kachulukidwe kakang'ono, mphamvu zenizeni zenizeni komanso kukana kutentha kwambiri, motero imagwiritsidwa ntchito kwambiri muzamlengalenga ndi minda yofananira. Koma choyipa chake ndikuti sichimamva kuvala, chosavuta kukanda komanso chosavuta kukhala oxidized. Anodizing ndi imodzi mwa njira zothandiza kuthana ndi zofooka izi.
Titaniyamu ya anodized imatha kugwiritsidwa ntchito kukongoletsa, kumaliza, komanso kukana dzimbiri mumlengalenga. Pamalo otsetsereka, imatha kuchepetsa mikangano, kuwongolera kuwongolera kwamafuta, komanso kupereka mawonekedwe okhazikika.
M'zaka zaposachedwa, titaniyamu yakhala ikugwiritsidwa ntchito bwino m'minda ya biomedicine ndi ndege chifukwa champhamvu zake zapamwamba monga mphamvu zenizeni, kukana dzimbiri, komanso kuyanjana kwachilengedwe. Komabe, kusamva bwino kwake kumachepetsanso kugwiritsa ntchito titaniyamu. Ndi kubwera kwa ukadaulo wa kubowola anodizing, kuipa kwake kwatha. Ukadaulo wa anodizing makamaka kukhathamiritsa katundu wa titaniyamu pakusintha magawo monga makulidwe a filimu ya okusayidi.
