Anodized Anodic Structure Ntawm Aluminium

1) Anodic oxide zaj duab xis qauv Anodic oxide zaj duab xis yog tsim los ntawm ob txheej, txheej txheej txheej yog hu ua ntxeem tau txheej, tuab, xoob xoob, tsis muaj zog. Cov txheej sab hauv yog hu ua txheej txheej barrier (tseem hu ua cov txheej txheem nquag), uas yog nyias, ntom thiab muaj kev ua haujlwm siab. Cov txheej txheej ntxeem tau loj hlob nyob rau sab saum toj ntawm cov txheej sab hauv nrog cov khoom dielectric. Nyob rau hauv dav dav, anodic oxide zaj duab xis yog ib tug series ntawm hexagonal kab, txhua kem muaj ib lub hnub qub-zoo li lub qhov uas muaj cov tshuaj, cov duab ntawm ib tug honeycomb qauv, lub qhov phab ntsa thickness yog ob zaug ntawm txoj kab uas hla ntawm lub pore.

(1) Barrier txheej Barrier txheej yog tsim los ntawm anhydrous AI2O3, nyias thiab ntom, nrog siab hardness thiab cov nyhuv ntawm kev tiv thaiv kev hla ntawm tam sim no. (2) Porous txheej oxide zaj duab xis Porous txheej txheej yog tsim los ntawm amorphous AI2O3 thiab ib tug me me ntawm r-AI2O3.H2O kuj muaj electrolyte anion.

Qhov pore loj ntawm oxide zaj duab xis yog nyob nruab nrab ntawm 100nm thiab 200nm, lub thickness ntawm cov oxide zaj duab xis yog hais txog 10 microns, lub porosity yog hais txog 20 feem pua, thiab lub pore deb ntawm 300 nm thiab 500nm. Qhov hla ntawm cov yeeb yaj kiab oxide qhia tau hais tias lub qhov oxide zaj duab xis yog cov qauv tubular, thiab cov tshuaj tiv thaiv kev sib cais ntawm cov oxide zaj duab xis yog qhov tseem ceeb hauv qab ntawm lub qhov. Thiab qhov dav dav sulfuric acid DC anodic oxidation zaj duab xis aperture yog hais txog 20nm, yog tias nws yog 12 micron oxide zaj duab xis, nws yog qhov tob npaum li cas ntawm cov tubular zoo ah! Piv txwv tias qhov no yog 1m txoj kab uas hla, nws yuav yog 600m tob.

Feem ntau ntawm cov khoom zoo heev ntawm oxide zaj duab xis, xws li corrosion kuj, hnav tsis kam, adsorption, rwb thaiv tsev thiab lwm yam khoom yog txiav txim siab los ntawm thickness thiab porosity ntawm cov ntxeem tau txheej txheej. Txawm li cas los xij, ob qho tib si muaj feem xyuam nrog cov xwm txheej anodizing, yog li cov xwm txheej anodizing tuaj yeem hloov pauv kom tau raws li cov kev xav tau ntawm kev siv cov yeeb yaj kiab sib txawv. Zaj duab xis thickness yog ib qho tseem ceeb ntawm kev ua tau zoo ntawm cov khoom anodized, thiab nws cov nqi ncaj qha cuam tshuam rau corrosion kuj, hnav tsis kam, rwb thaiv tsev thiab tshuaj lom neeg muaj peev xwm ntawm cov yeeb yaj kiab. Nyob rau hauv cov pa anodic oxidation txheej txheem, zaj duab xis thickens nrog lub sij hawm. Tom qab ncav cuag lub siab tshaj plaws thickness, lawv maj mam ua thinner nrog rau ncua sij hawm ua. Qee cov alloys, xws li AI-Mg thiab AI-Mg-Zn alloys, qhia qhov tshwm sim tshwj xeeb. Yog li ntawd, lub sij hawm ntawm oxidation feem ntau tswj nyob rau hauv lub sij hawm ntawm maximizing zaj duab xis thickness.

2) Cov khoom thiab kev siv ntawm anodic oxide zaj duab xis Anodic oxide zaj duab xis muaj zog dua thiab hnav tsis kam, muaj zog adhesion muaj peev xwm, muaj peev xwm adsorption, zoo corrosion kuj thiab hluav taws xob rwb thaiv tsev thiab thermal rwb thaiv tsev. Vim tias cov khoom tshwj xeeb no, nws tau siv dav hauv ntau yam.

Cov kev siv tseem ceeb yog: (1) txhim kho qhov hnav tsis kam, corrosion kuj, huab cua corrosion kuj ntawm qhov chaw. (2) Lub pob tshab zaj duab xis tsim los ntawm oxidation tuaj yeem ua xim rau ntau hom xim. (3) raws li ib tug capacitor dielectric zaj duab xis. (4) Txhim kho txoj hlua khi nrog cov organic txheej. Rau txheej puag. (5) rau electroplating, enamel hauv qab. (6) Lwm daim ntawv thov raug tsim, xws li hnub ci nqus vaj huam sib luag, ultra-high hardness films, qhuav lubrication films, catalyst films, nanowires, thiab deposition ntawm magnetic alloys nyob rau hauv porous films raws li lub cim xeeb.
