Cov txheej txheem xim anodic zoo ib yam li electroplating, thiab tsis muaj qhov tshwj xeeb rau cov electrolyte. Ntau yam kev daws teeb meem ntawm 10% sulfuric acid, 5% ammonium sulfate, 5% magnesium sulfate, 1% trisodium phosphate, thiab lwm yam, txawm tias cov kua dej ntawm cov cawv dawb tuaj yeem siv thaum xav tau. Feem ntau, cov tshuaj distilled aqueous ntawm 3% -5% los ntawm qhov hnyav ntawm trisodium phosphate tuaj yeem siv. Hauv cov txheej txheem xim kom tau txais cov xim muaj zog, cov electrolyte yuav tsum tsis txhob muaj chloride ions. Kub kub yuav ua rau cov electrolyte deteriorate thiab ua rau ib tug ntxeem tau oxide zaj duab xis, yog li cov electrolyte yuav tsum tau muab tso rau hauv qhov chaw txias.
Hauv anode coloring, thaj tsam ntawm cathode siv yuav tsum sib npaug los yog loj dua li ntawm cov anode. Kev kaw tam sim no yog qhov tseem ceeb hauv cov xim anodic, vim tias cov neeg ua yeeb yam feem ntau solder cov zis cathodic tam sim no ncaj qha rau cov hlau clip ntawm cov xim pleev xim, qhov chaw xim me me. Txhawm rau kom haum rau cov tshuaj tiv thaiv anode ceev thiab electrode loj nrog cov xim xim, thiab tiv thaiv cov oxide zaj duab xis los ntawm kev tawg thiab hluav taws xob corrosion vim muaj ntau dhau tam sim no, tam sim no yuav tsum txwv.
Kev siv thev naus laus zis anodizing hauv kev kho mob tshuaj thiab kev lag luam aerospace
Titanium yog cov khoom siv tsis muaj roj ntsha, thiab nws muaj teeb meem xws li kev sib koom ua ke tsis tshua muaj zog thiab lub sijhawm kho tau ntev thaum nws ua ke nrog cov pob txha, thiab nws tsis yooj yim rau kev tsim osseointegration. Yog li ntawd, ntau txoj kev yog siv rau kev kho deg ntawm titanium implants los txhawb cov deposition ntawm HA nyob rau saum npoo los yog txhim khu cov adsorption ntawm biomolecules los txhim kho nws cov khoom lom. Hauv kaum xyoo dhau los, TiO2 nanotubes tau txais kev saib xyuas zoo vim lawv cov khoom zoo heev. Hauv vitro thiab hauv vivo kev sim tau lees paub tias nws tuaj yeem ua rau muaj qhov tso tawm ntawm hydroxyapatite (HA) ntawm nws qhov chaw thiab txhim kho lub zog sib txuas ntawm qhov sib txuas, yog li txhawb nqa qhov adhesion thiab kev loj hlob ntawm osteoblasts ntawm nws qhov chaw.
Cov txheej txheem ntawm kev kho saum npoo muaj xws li txheej txheej txheej txheej txheej, hydrothermal kev kho Electrochemical oxidation yog ib txoj hauv kev yooj yim los npaj TiO2 nanotubes tsis tu ncua. Hauv qhov kev sim no, cov xwm txheej rau kev npaj TiO2 nanotubes thiab cov nyhuv ntawm TiO2 nanotubes ntawm qhov cuam tshuam ntawm cov dej ntxhia ua haujlwm ntawm titanium nto hauv SBF tov.
Titanium muaj qhov tsis tshua muaj zog, lub zog muaj zog tsawg dua thiab kub tsis kam, yog li nws tau siv dav hauv ib lub teb thiab lwm daim teb. Tab sis qhov tsis zoo yog tias nws tsis tiv taus hnav, yooj yim rau khawb thiab yooj yim rau oxidized. Anodizing yog ib txoj hauv kev zoo los kov yeej cov kev tsis zoo no.
Anodized titanium tuaj yeem siv rau kev kho kom zoo nkauj, ua tiav, thiab ua haujlwm rau atmospheric corrosion. Ntawm qhov zawv zawg qhov rooj, nws tuaj yeem txo kev sib txhuam, txhim kho thermal tswj, thiab muab kev ua haujlwm ruaj khov kho qhov muag.
Nyob rau hauv xyoo tas los no, titanium tau zoo siv nyob rau hauv biomedicine thiab aviation vim nws superior zog xws li lub zog tshwj xeeb, corrosion kuj, thiab biocompatibility. Txawm li cas los xij, nws cov kev hnav tsis zoo kuj tseem txwv tsis pub siv titanium. Nrog lub advent ntawm laum anodizing tshuab, qhov tsis zoo ntawm nws tau kov yeej. Anodizing thev naus laus zis feem ntau yog txhawm rau txhim kho cov khoom ntawm titanium rau kev hloov pauv tsis xws li cov tuab ntawm oxide zaj duab xis.
