Anodizing: zotayidwa ndi kasakaniza wazitsulo ake ntchito ngati anodes, ndi kutsogolera kapena graphite ntchito ngati cathodes. Mu ndende zina (monga chidulo cha safuriki, asidi oxalic, asidi chromic, etc.) yankho conductive, kupyolera ntchito voteji ndi zotsatira za magetsi, ndi makulidwe ena (8-12um) wosanjikiza aumbike padziko kampaniyo, amene ali katundu wabwino makina, kuuma, kukana dzimbiri, kuvala kukana, kutchinjiriza, adsorbability ndi zina zotero.
1. Degreasing: organic zosungunulira degreasing, madzi zochokera emulsification kuyeretsa wothandizila degreasing, electrochemical degreasing.
2. Chemical kupukuta: Komanso kuchotsa litsiro padziko zotayidwa ndi aloyi ake ndi asidi phosphoric, ndi kuchotsa zachilengedwe okusayidi filimu padziko lapansi aloyi zotayidwa, kotero kuti gawo lapansi zotayidwa poyera kuti atsogolere wotsatira anodization. Pa nthawi yomweyo, kupukuta ali ndi zotsatira za kukhazikika, amene angathe zina kusalaza pamwamba pa workpiece pambuyo sandblasting, ndi kapangidwe pamwamba bwino.
3. khungu lakuda filimu: After phosphorylation, wakuda imvi filimu (zitsulo monga mkuwa, faifi tambala, manganese, chitsulo, pakachitsulo, etc., amene ali insoluble mu chidulo phosphoric) amakhalabe padziko workpiece, ndiyeno mankhwala asidi nitric.
4. makutidwe ndi okosijeni: The ndondomeko ya musayambe okusayidi kanema ndi mankhwala zotayidwa (anode) pansi kanthu ya panopa Akutsatira pansi pa electrolyte lolingana ndi zinthu zenizeni m. Anodic makutidwe ndi okosijeni, ngati sizinafotokozedwe, kawirikawiri amatanthauza anodizing asidi sulfuric.
5. ankaudaya: ankaudaya zizichitidwa yomweyo pambuyo anode ndipo osati kale kwambiri. Pambuyo makutidwe ndi okosijeni mosamala muzimutsuka pa asidi yotsalira ndi madzi ozizira (kupewa kuwuka kutentha ndi Kakhungu ali basi losindikizidwa).
6. Kusindikiza: mkulu kutentha zisindikizo otentha madzi pores, ndi aluminiyamu Chili ndi tinthu madzi kupanga hydrates, kupanga mibulu.
7. Kuyanika: Place mankhwala mu ng'anjo ndi kutentha uvuni pa 70 ° C. Kusindikiza kutentha sayenera kukhala wovulaza, mwinamwake filimu sachedwa ming'alu. Pamaso kutsuka ziyenera kutsukidwa ndi madzi otentha kuonjezera kutentha kwa workpiece kuti kupewa osokoneza chifukwa workpiece kukhala ozizira kwambiri.
