I-Anodizing: i-aluminium kanye nama-alloy ayo asetshenziswa njenge-anode, kanti i-lead noma i-graphite kusetshenziswa njenge-cathode. Esixazululweni esithile sokudonsa (njenge-sulfuric acid, i-oxalic acid, i-chromic acid, njll.), ngokusebenzisa i-voltage esetshenzisiwe kanye nomphumela wamandla kagesi, kwakheka ungqimba oluthile lobukhulu (8-12um) ebusweni benkampani, olunezakhiwo ezinhle zomshini, ubulukhuni, ukumelana nokugqwala, ukumelana nokuguguleka, ukufudumala, ukunamathela njalo njalo.
1. Ukususa amafutha: ukususa amafutha ngesinyibilikisi se-organic, ukususa amafutha nge-emulsification esuselwe emanzini, ukususa amafutha nge-electrochemical.
2. Ukupholisha ngamakhemikhali: Ukususa ukungcola ebusweni be-aluminium kanye ne-alloy yayo nge-phosphoric acid, nokususa ifilimu ye-oxide yemvelo ebusweni be-alloy ye-aluminium, ukuze i-substrate ye-aluminium ivezwe ukuze kube lula ukupholisha okulandelayo. Ngesikhathi esifanayo, ukupholisha nakho kunomphumela wokulinganisa, okungashelela kakhulu ubuso bento yokusebenza ngemva kokupholisha ngesihlabathi, futhi ukuthungwa kobuso kube ngcono.
3. Ifilimu emnyama ehlubulayo: Ngemva kwe-phosphorylation, ifilimu emnyama-grey (insimbi efana nethusi, i-nickel, i-manganese, insimbi, i-silicon, njll., enganyibiliki ku-phosphoric acid) ihlala phezu kwento yokusebenza, bese iphathwa nge-nitric acid.
4. Ukuxutshwa kwe-oksidashini: Inqubo yokwakha ifilimu ye-oksidashini kumkhiqizo we-aluminium (i-anode) ngaphansi kwesenzo somsinga osetshenziswayo ngaphansi kwe-electrolyte ehambisanayo kanye nezimo ezithile ze-s. Ukuxutshwa kwe-anodic, uma kungacacisiwe, ngokuvamile kusho i-Anodizing sulfuric acid.
5. Ukudaya: Ukudaya kufanele kwenziwe ngokushesha ngemva kwe-anode futhi kungabi isikhathi eside kakhulu. Ngemva kokudaya, hlanza ngokucophelela i-asidi esele ngamanzi abandayo (gwema ukwenyuka kwezinga lokushisa bese ulwelwesi luvalwa ngokuzenzakalelayo).
6. Ukuvala: amanzi abilayo ashisa kakhulu avala izimbobo, bese i-alumina ihlangana nama-molecule amanzi ukuze kwakheke ama-hydrate, kwakhiwe amakristalu.
7. Ukomisa: Beka umkhiqizo kuhhavini lapho izinga lokushisa lehhavini libekwe ku-70 °C. Izinga lokushisa lokuvala akufanele libe phezulu kakhulu, ngaphandle kwalokho ifilimu ivame ukuqhekeka. Ngaphambi kokuwasha, kumele igezwe ngamanzi ashisayo ukuze kwandiswe izinga lokushisa le-workpiece ukuze kugwenywe ukuqhekeka okubangelwa ukuthi i-workpiece ibanda kakhulu.
