Muaj ntau txoj hauv kev ntawm kev kho deg ntawm aluminium alloy

Sandblasting, lub luag haujlwm tseem ceeb yog los ntxuav qhov chaw, sandblasting ua ntej tha xim (thaum pleev xim los yog txau) tuaj yeem ua rau lub ntsej muag roughness, thiab muaj qee yam kev pab cuam rau kev txhim kho ntawm adhesion, tab sis qhov kev koom tes yog txwv, nws tsis zoo li tshuaj txheej ua ntej kev kho mob.
Passivation yog txoj kev hloov cov hlau nto rau hauv lub xeev uas tsis yooj yim rau oxidized, thiab ncua qhov corrosion ntawm cov hlau.
Xim: Muaj ob txoj haujlwm tseem ceeb rau xim xim txhuas: ib qho yog txhuas oxidation txheej txheem xim, thiab lwm yam yog txhuas electrophoresis xim txheej txheem. Ntau yam xim yog tsim los ntawm oxide zaj duab xis kom ua tau raws li qee qhov yuav tsum tau ua, xws li xim dub rau cov khoom siv kho qhov muag thiab kub rau kev ua koob tsheej MEDALS.
Conductive oxidation (chromate conversion film) - siv nyob rau hauv cov xwm txheej uas yuav tsum tau muaj kev tiv thaiv thiab conductivity.
Tshuaj polishing Tshuaj polishing yog ib txoj kev ua tshuaj uas siv cov kev xaiv ntawm tus kheej -solution ntawm txhuas thiab aluminium alloys nyob rau hauv acidic los yog alkaline electrolyte daws kom du thiab polishing nto ntawm lub xyoo kom txo nws cov nto roughness thiab PH.
Txoj kev polishing no muaj qhov zoo ntawm cov khoom siv yooj yim, tsis muaj hluav taws xob, tsis txwv los ntawm cov duab loj ntawm lub workpiece, siab polishing ceev thiab cov nqi qis. Lub purity ntawm txhuas thiab txhuas alloy muaj kev cuam tshuam zoo ntawm cov tshuaj polishing zoo, qhov siab dua nws cov purity, qhov zoo ntawm polishing zoo, thiab qhov phem dua nws yog.
Tshuaj oxidation: oxide zaj duab xis yog nyias, tuab yog li 0.5 ~ 4 microns, thiab ntxeem tau, mos, nrog zoo adsorption, yuav siv tau raws li hauv qab txheej ntawm organic txheej, tab sis nws hnav tsis kam thiab corrosion kuj tsis zoo li anodic oxidation zaj duab xis;
Cov txheej txheem tshuaj oxidation ntawm txhuas thiab txhuas hlau tuaj yeem muab faib ua ob pawg raws li cov khoom ntawm nws cov tshuaj: alkaline oxidation method thiab acid oxidation method.
Raws li cov khoom ntawm txheej zaj duab xis, nws tuaj yeem muab faib ua: oxide zaj duab xis, phosphate zaj duab xis, chromate zaj duab xis, chroma-phosphate zaj duab xis.
Txau: siv rau kev tiv thaiv sab nraud thiab kho kom zoo nkauj ntawm cov khoom siv, feem ntau yog los ntawm oxidation. Aluminium qhov chaw yuav tsum tau ua ntej- kho ua ntej txheej txhawm rau ua kom cov txheej thiab cov khoom ua haujlwm ruaj khov ua ke, feem ntau muaj peb txoj hauv kev: phosphating (phosphate method), chromium (tsis muaj chromium chromium), tshuaj oxidation.
Electrochemical oxidation, aluminium thiab aluminium alloy tshuaj oxidation kho cov cuab yeej yog yooj yim, yooj yim rau kev khiav lag luam, siab ntau lawm efficiency, tsis siv hluav taws xob, ntau yam ntawm daim ntawv thov, tsis txwv los ntawm qhov loj thiab cov duab ntawm qhov chaw. Lub thickness ntawm oxide zaj duab xis yog hais txog 5 mus rau 20 microns (lub thickness ntawm lub hard anodic oxide zaj duab xis muaj peev xwm ncav cuag 60 mus rau 200 microns), muaj zog hardness, zoo tshav kub kuj thiab rwb thaiv tsev, corrosion kuj yog siab dua li ntawm cov tshuaj oxide zaj duab xis, ntxeem tau, thiab muaj peev xwm adsorption zoo.
