ʻO ke kaʻina hana kala anodic e like me ka electroplating, a ʻaʻohe koi kūikawā no ka electrolyte.ʻO nā ʻano wai like ʻole o 10% sulfuric acid, 5% ammonium sulfate, 5% magnesium sulfate, 1% trisodium phosphate, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia ka wai wai o ka waina keʻokeʻo inā pono.ʻO ka maʻamau, hiki ke hoʻohana ʻia kahi hoʻonā wai wai o 3% -5% ma ke kaumaha o ka trisodium phosphate.Ma ke kaʻina hana kala no ka loaʻa ʻana o ke kala uila kiʻekiʻe, ʻaʻole pono i ka electrolyte nā ion chloride.ʻO ke kiʻekiʻe ka wela e hoʻopōʻino ai ka electrolyte a hana i kahi kiʻiʻoniʻoni porous oxide, no laila pono ke kau ʻia ka electrolyte ma kahi anuanu.
I ke kala anode, pono e like a i ʻole ka nui o ka ʻāpana o ka cathode i hoʻohana ʻia ma mua o ka anode.He mea koʻikoʻi ka hoʻopaʻa ʻana i kēia manawa ma ke kala anodic, no ka mea, kūʻai pinepine nā mea pena kiʻi i ka huahana cathodic current pololei i ka pahu metala o ka pulu pena, kahi liʻiliʻi ka wahi kala.I mea e hoʻohālikelike ai i ka wikiwiki o ka anode a me ka nui o ka electrode me ka wahi kala, a pale i ke kiʻi oxide mai ka haki ʻana a me ka ʻino uila ma muli o ka nui o ke au, pono e kaupalena ʻia ka manawa.
Hoʻohana i ka ʻenehana anodizing i ka lāʻau lapaʻau a me ka ʻoihana aerospace
ʻO ka Titanium kahi mea inert biologically, a he mau pilikia e like me ka ikaika hoʻopaʻa haʻahaʻa a me ka manawa hoʻōla lōʻihi ke hui pū ʻia me ka iwi iwi, a ʻaʻole maʻalahi ka hana osseointegration.No laila, hoʻohana ʻia nā ʻano hana like ʻole no ka mālama ʻana i ka ʻili o nā implants titanium e hāpai i ka waiho ʻana o HA ma ka ʻili a i ʻole e hoʻonui i ka adsorption o nā biomolecules e hoʻomaikaʻi i kāna hana olaola.I nā makahiki i hala iho nei, ua loaʻa i nā nanotubes TiO2 ka nānā nui ʻana ma muli o kā lākou mau waiwai maikaʻi.Ua hōʻoia nā hoʻokolohua in vitro a me in vivo hiki iā ia ke hoʻoulu i ka waiho ʻana o ka hydroxyapatite (HA) ma luna o kona ʻili a hoʻonui i ka ikaika hoʻopaʻa ʻana o ka interface, a laila e hoʻoikaika ai i ka hoʻopili ʻana a me ka ulu ʻana o nā osteoblasts ma luna o kona ʻili.
ʻO nā ʻano hana maʻamau o ka mālama ʻana i ka ʻili he ala solgel layer, hydrothermal treatment Electrochemical oxidation ʻo ia kekahi o nā ala kūpono e hoʻomākaukau ai i nā nanotubes TiO2 i hoʻonohonoho mau ʻia.Ma kēia hoʻokolohua, nā kūlana no ka hoʻomākaukau ʻana i nā nanotubes TiO2 a me ka hopena o TiO2 nanotubes i ka Influence o ka hana mineralization o ka ʻili titanium i ka hopena SBF.
He haʻahaʻa haʻahaʻa haʻahaʻa ka Titanium, ikaika kikoʻī kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, no laila ua hoʻohana nui ʻia i ka aerospace a me nā māla pili.Akā ʻo ka hemahema ʻo ia ʻaʻole kūʻokoʻa i ka ʻaʻahu, maʻalahi e ʻoki a maʻalahi hoʻi e oxidized.ʻO ka anodizing kekahi o nā ala kūpono e lanakila ai i kēia mau hemahema.
Hiki ke hoʻohana ʻia ka titanium anodized no ka hoʻonaninani, hoʻopau ʻana, a me ke kūʻē ʻana i ka corrosion atmospheric.Ma ka ʻili hoʻoheheʻe, hiki iā ia ke hōʻemi i ka friction, hoʻomaikaʻi i ka mana wela, a hāʻawi i ka hana optical paʻa.
I kēia mau makahiki i hala iho nei, ua hoʻohana maikaʻi ʻia ka titanium i nā kula o ka biomedicine a me ka mokulele ma muli o kāna mau waiwai kiʻekiʻe e like me ka ikaika kikoʻī kiʻekiʻe, ke kūpaʻa corrosion, a me ka biocompatibility.Eia nō naʻe, ʻaʻole i kaupalena ʻia kona hoʻohana ʻana i ka titanium.Me ka hiki ʻana mai o ka ʻenehana drill anodizing, ua lanakila kēia hemahema o ia mea.ʻO ka ʻenehana anodizing ka mea nui e hoʻomaikaʻi i nā waiwai o ka titanium no ka hoʻololi ʻana o nā ʻāpana e like me ka mānoanoa o ke kiʻi oxide.
