Anodizing: A na-eji aluminom na alloys ya eme ihe dị ka anode, a na-ejikwa lead ma ọ bụ graphite eme ihe dị ka kathodes. N'ime oke ụfọdụ (dị ka sulfuric acid, oxalic acid, chromic acid, wdg) ngwọta na-eduzi ihe, site na voltaji etinyere na mmetụta nke ọkụ eletrik, a na-emepụta oyi akwa ọkpụrụkpụ (8-12um) n'elu ụlọ ọrụ ahụ, nke nwere ezigbo ihe onwunwe igwe, ike, iguzogide nchara, iguzogide iyi, mkpuchi, nnabata na ihe ndị ọzọ.
1. Ịchacha mmanụ: Ịchacha ihe mgbaze organic, ịchacha ihe nhicha nke emulsification dabere na mmiri, ịchacha mmanụ electrochemical.
2. Ịchacha kemịkalụ: Wepụ ájá dị n'elu aluminom na ihe ndị ọzọ e ji phosphoric acid mee, ma wepụ ihe nkiri oxide eke dị n'elu aluminom, ka ihe ndị e ji echekwa aluminom ahụ pụta ìhè iji mee ka anodization na-esote dị mfe. N'otu oge ahụ, ịchacha ahụ nwekwara mmetụta nke ịchacha, nke nwere ike ime ka elu nke ihe e ji arụpụta ihe dịkwuo mma mgbe a gbasasịrị ájá, ọdịdị elu ahụ ka mma.
3. Ịkpụcha ihe nkiri ojii: Mgbe phosphorylation gasịrị, ihe nkiri ojii-isi awọ (ọla dịka ọla kọpa, nickel, manganese, iron, silicon, wdg, nke na-anaghị agbaze na phosphoric acid) na-anọgide n'elu ihe eji arụ ọrụ ahụ, wee jiri nitric acid gwọọ ya.
4. Oxidation: Usoro nke imepụta ihe nkiri oxide na ngwaahịa aluminom (anode) n'okpuru ọrụ nke ọkụ eletrik etinyere n'okpuru electrolyte kwekọrọ na ọnọdụ s kpọmkwem. Oxidation Anodic, ọ bụrụ na akọwapụtaghị ya, na-apụtakarị Anodizing sulfuric acid.
5. Ịcha agba: A ga-eme agba ozugbo emechara anode ahụ, ọ gaghị adị ogologo oge. Mgbe emechara oxidation, jiri mmiri oyi sachaa asịd fọdụrụnụ nke ọma (zere mmụba okpomọkụ ma mechie akpụkpọ ahụ ozugbo).
6. Mkpuchi: mmiri ọkụ dị elu na-emechi oghere ndị ahụ, alumina na-ejikọtakwa ya na molekul mmiri iji mepụta mmiri mmiri, na-emepụta kristal.
7. Ịkpọ nkụ: Tinye ngwaahịa ahụ n'ime oven nke nwere okpomọkụ oven na 70 °C. Okpomọkụ mkpuchi ekwesịghị ịdị oke elu, ma ọ bụghị ya, ihe nkiri ahụ nwere ike ịgbawa agbawa. Tupu ịsa ya, a ga-eji mmiri ọkụ saa ya iji mee ka okpomọkụ nke ihe eji arụ ọrụ dịkwuo elu ka ọ ghara ịgbawa agbawa nke ihe eji arụ ọrụ ahụ kpatara.
