I-Anodizing: i-aluminium kunye nee-alloys zayo zisetyenziswa njengee-anode, kwaye i-lead okanye i-graphite zisetyenziswa njengee-cathodes. Kwisisombululo esiqhubayo (njenge-sulfuric acid, i-oxalic acid, i-chromic acid, njl.njl.), ngokusebenzisa i-voltage esetyenzisiweyo kunye nefuthe lombane wamandla, kwakheka umaleko othile wobukhulu (8-12um) phezu komphezulu wefemu, oneempawu ezilungileyo zoomatshini, ubulukhuni, ukumelana nokugqwala, ukumelana nokuguguleka, ukugquma, ukunamathela njalo njalo.
1. Ukususa amafutha: ukususa amafutha kwisinyibilikisi sendalo, ukususa amafutha kwi-emulsification esebenzisa amanzi, ukususa amafutha kwi-electrochemical.
2. Ukupholisha ngekhemikhali: Ukususa ukungcola phezu komphezulu we-aluminium kunye ne-alloy yayo nge-phosphoric acid, kunye nokususa ifilimu ye-oxide yendalo phezu komphezulu we-alloy ye-aluminium, ukuze i-substrate ye-aluminium ivezwe ukuze kube lula ukupholisha okulandelayo. Kwangaxeshanye, ukupholisha kukwanefuthe lokulinganisa, okunokugudisa umphezulu wento yokusebenza emva kokupholisha ngesanti, kwaye ubume bomphezulu bube ngcono.
3. Ifilimu emnyama exobukayo: Emva kwe-phosphorylation, ifilimu emnyama-grey (isinyithi esifana ne-copper, nickel, manganese, isinyithi, i-silicon, njl.njl., esinganyibilikiyo kwi-phosphoric acid) ihlala phezu kwendawo yokusebenza, ize iphathwe nge-nitric acid.
4. Ukuxinana: Inkqubo yokwenza ifilimu ye-oxide kwimveliso ye-aluminium (i-anode) phantsi kwesenzo sombane osetyenziswayo phantsi kwe-electrolyte ehambelanayo kunye neemeko ezithile ze-s. Ukuxinana kwe-anodic, ukuba akucaciswanga, kudla ngokuthetha i-Anodizing sulfuric acid.
5. Ukudaya: Ukudaya kufuneka kwenziwe kwangoko emva kwe-anode kwaye kungabi lixesha elide kakhulu. Emva kokudaya, hlambulula ngononophelo i-acid eseleyo ngamanzi abandayo (thintela ukunyuka kobushushu kwaye i-membrane ivalwe ngokuzenzekelayo).
6. Ukutywina: amanzi abilayo kubushushu obuphezulu ayawavala amaxolo, kwaye i-alumina idibana neemolekyuli zamanzi ukwenza ii-hydrate, zenze iikristale.
7. Ukomisa: Beka imveliso kwi-oven apho ubushushu be-oven bubekwe kwi-70 °C. Ubushushu bokuvala akufuneki bube phezulu kakhulu, kungenjalo ifilimu inokuba neentanda. Ngaphambi kokuba ihlanjwe, kufuneka ihlanjwe ngamanzi ashushu ukuze kwandiswe ubushushu be-workpiece ukuze kuthintelwe ukuqhekeka okubangelwa kukuba i-workpiece ibanda kakhulu.
