Anodizing: aluminium futhi Alloys yayo ezisetshenziswa njengeziwusizo anodes, uhole noma graphite ezisetshenziswa njengeziwusizo cathodes. Ngo lokuhlushwa ezithile (njengokuthi sulfuric acid, oxalic acid, chromic acid, njll) isixazululo conductive, ngokusebenzisa voltage isicelo futhi umphumela kagesi, kwakheka eqinile (8-12um) ungqimba phezu ngokuqinile, okuyinto has izakhiwo ezinhle mechanical, ubulukhuni, ukugqwala ukumelana, ukugqoka ukumelana, ukwahlukanisa, adsorbability nokunye.
1. Degreasing: organic kuphela degreasing, amanzi based emulsification yokuhlanza ejenti degreasing, degreasing electrochemical.
2. Chemical wokucwebezelisa: Eminye nokususa ukungcola phezu aluminium and ingxubevange yayo nge wali band acid, nokususa zemvelo oxide ifilimu phezu ingxubevange aluminium, ukuze substrate aluminium echayeke lula anodization okwalandela. Ngesikhathi esifanayo, le ezipholisha Ubuye umphumela yokululama, okungaba eminye bushelelezi ebusweni workpiece ngemva sandblasting, futhi ukuthungwa ebusweni kungcono.
3. uyaxebuka black ifilimu: Ngemva phosphorylation, ifilimu black-grey (metal ezifana nethusi, nickel, manganese, insimbi, Silicon, njll, okuyinto zingaxazululeki wali band acid) uhlala phezu workpiece, bese ziphathwe nitric acid.
4. Ukulumbanisa nge-oksijini: Inqubo azakhele ifilimu oxide ku umkhiqizo aluminium (anode) ngaphansi isenzo i wamanje osetshenziswayo ngaphansi electrolyte elihambisana nemibandela ethize s. Anodic namachibi, uma kungenjalo bucaciswe, ngokuvamile lisho Anodizing sulfuric acid.
5. Ukudaya: Ukudaya kufanele kwenziwe ngokushesha emva anode hhayi isikhathi eside kakhulu. Ngemva namachibi, kugeze kahle off the asalile acid ngamanzi abandayo (ukugwema ukwanda lokushisa kanye ulwelwesi ngokuzenzakalelayo uphawu).
6. ukubekwa uphawu: lokushisa eliphezulu amanzi abilayo lwezimpawu ezimbotsheni, futhi alumina ihlanganisa ne-molecule yamanzi ukwakha hydrates, ukwakha zinhlayiya.
7. Omiswe: Indawo umkhiqizo kuhhavini ne lokushisa kuhhavini lishone 70 ° C. Amazinga ukubekwa uphawu akufanele kube abawasebenzisayo, kungenjalo ifilimu uthambekela imifantu. Ngaphambi wokuwasha, kumelwe sihlanzwe ngamanzi ashisayo ukwandisa izinga lokushisa kwe-workpiece ukuze ukugwema ukwambula kubangelwa workpiece alinaluthando kakhulu.
