Muaj ob peb lub npe sib txawv rau lub npe ntawm anodized aluminium daim ntawv loCov. Feem ntau nws cov npe nyob hauv ib txwm hu ua electrochemical oxidation ntawm hlau lossis alloy. Lub npe niaj hnub no hu ua anode daim ntawv lossis oxidation daim ntawv lo, thiab lub npe tshaj lij yog sulfuric acid anodizing.
Zaj duab xis txheej ntawm txhuas thiab txhuas hlau tom qab anodic oxidation muaj qhov zoo sib xws:
(1) Lub siab tawv
Feem ntau, nws lub hardness muaj feem xyuam nrog cov khoom sib xyaw ua ke ntawm aluminium thiab cov txheej txheem technical ntawm cov roj ntsha thaum lub sijhawm anodization. Lub anodic oxide zaj duab xis tsis tsuas yog muaj lub zog siab dua, tab sis kuj tseem muaj hnav zoo dua. Hauv tshwj xeeb, qhov ntxeem tau oxide zaj duab xis ntawm txheej txheej sab saum toj muaj peev xwm adsorb roj nplua nyeem thiab tuaj yeem txuas ntxiv txhim kho qhov hnav tsis kam ntawm qhov saum npoo.
(2) Muaj kev tiv thaiv siab corrosion
Qhov no yog vim lub siab cov tshuaj lom neeg ruaj khov ntawm zaj duab xis anodic oxide. Cov. Feem ntau, cov yeeb yaj kiab tau tom qab anodic oxidation yuav tsum tau muab khi ua ke los txhim kho nws qhov kev txhim kho corrosion.
(3) muaj qhov muaj zog adsorption muaj zog
Cov anodic oxide zaj duab xis ntawm txhuas thiab aluminium alloy muaj cov qauv ntxeem tau thiab muaj lub zog muaj peev xwm adsorption
(4) Kev rwb thaiv tsev zoo
Cov anodic oxide zaj duab xis ntawm aluminium thiab aluminium alloy tsis muaj cov khoom zoo conductive ntawm cov hlau, thiab dhau los ua cov khoom siv insulating zoo.
(5) Muaj zog thermal rwb thaiv tsev thiab tiv taus tshav kub
Qhov no yog vim tias lub thermal conductivity ntawm aluminium anodic oxide zaj duab xis yog ntau qis dua li ntawm cov ntshiab aluminium. Cov anodic oxide zaj duab xis tuaj yeem tiv taus kub txog 1500 ° C, thaum ntshiab txhuas tau tuaj yeem tiv taus 660 ° C.
