Anodizing: aluminum na ya alloys na-eji dị ka anodes, ma na-edu ma ọ bụ graphite na-eji dị ka cathodes. Na a na-ịta (dị ka na igirigi ibu sulphuric acid, oxalic acid, chromic acid, wdg) conductive solution, site etinyere voltaji na mmetụta nke eletrik, a ụfọdụ ọkpụrụkpụ (8-12um) oyi akwa a kpụrụ n'elu nke ike, nke nwere ezi n'ibu Njirimara, ekweghị ekwe, corrosion eguzogide, na-eyi ndị na-eguzogide, mkpuchi, adsorbability na na.
1. Degreasing: organic mgbaze degreasing, mmiri dabeere emulsification ihicha gị n'ụlọnga degreasing, electrochemical degreasing.
2. Chemical polishing: Ọzọkwa wepụ ájá n'elu aluminum na ya alloy na phosphoric acid, na wepụ eke oxide film n'elu nke aluminum alloy, nke mere na aluminum mkpụrụ n'anwụ ikwado ụdi anodization. N'otu oge ahụ, na polishing nakwa nwere mmetụta nke leveling, nke nwere ike n'ihu-eji ire ụtọ elu nke workpiece mgbe sandblasting, na n'elu udidi bụ mma.
3. ekpepụsị black film: Mgbe phosphorylation, a nwa-agba ntụ film (metal dị ka ọla kọpa, nickel, manganese, ígwè, sịlịkọn, wdg, nke bụ unyi anaghị agbasa na phosphoric acid) na-anọgide na-elu nke workpiece, na mgbe ahụ-emeso ya na nitric acid.
4. ọxịdashọn: The usoro nke akpụ ihe oxide film na ihe aluminum ngwaahịa (anode) n'okpuru ihe nke ihe etinyere ugbu a n'okpuru kwekọrọ ekwekọ electrolyte na kpọmkwem s ọnọdụ. Anodic ọxịdashọn, ma ọ bụrụ na ọ bụghị kpọmkwem, na-emekarị pụtara Anodizing na igirigi ibu sulphuric acid.
5. Dyeing: Dyeing ga-eme ozugbo anode na bụghị kwa ogologo. Mgbe ọxịdashọn, jiri nlezianya itucha kwụsịrị mmapụta acid na mmiri oyi (zere okpomọkụ ịrị elu na akpụkpọ ahụ na-akpaghị aka-akàrà).
6. akara: elu okpomọkụ esi mmiri akàrà ndị pores, na alumina agwakọta na mmiri na ụmụ irighiri ihe na-etolite hydrates, akpụ kristal.
7. Ihicha: Ebe ngwaahịa na oven na oven okpomọkụ atọrọ na 70 ° C. The akara okpomọkụ ekwesịghị kwa elu, ma ọ bụghị film bụ ewekarị cracks. Tupu ịsa, ọ ga-na-asa na mmiri ọkụ na-amụba okpomọkụ nke workpiece ka ezere ịgbawa mere site workpiece ndidi kwa oyi.
