Ọgwụgwọ anodizing
Ụkpụrụ bụ isi: aluminum cathodic oxidation bụ n'ezie electrolysis nke mmiri, mgbe mmiri electrolysis pụtara O2- ion na anode aluminum mmeghachi omume na-etolite aluminum oxide (Al2O3) General electrolyte nhọrọ nke sulfuric acid, chromic acid, phosphoric acid, oxalic acid, n'ihe dịka 0c sulfuric acid iji mepụta ihe nkiri oxide siri ike. Ihe dị iche iche nwere mmetụta dị ukwuu na ihe nkiri oxide. Nke 6000 usoro Al-Si (6063.6061.6065), ọ bụghị naanị ihe nkiri oxide nchebe nwere ike ịmepụta, ma na-esiji ihe nkiri oxide, na ihe nkiri oxide na-egbuke egbuke, ma maka nkedo aluminum alloy, Enwere ike ịmepụta ihe nkiri oxide nchebe, ma ihe nkiri oxide agba nwere ike n'ozuzu na-etolite ike agba.
Ọgwụgwọ agba nke cathodic oxidation, enwere ọtụtụ ụzọ maka ịcha agba dịka ndị a.
Electrolytic agba usoro.
Usoro bụ: Aluminom alloy akụkụ mgbe anodic oxidation na-etinye na electrolyte nke metal nnu na electrolyzed ọzọ, nke mere na a na-etinye cations nke nnu ígwè n'ime ala oyi akwa nke ihe nkiri oxide pinhole na agba., na agba ọla na agba ojii nwere ike nweta na ngwa bara uru, na-emekarị site na ngwọta nnu nke Ni,Co,Sn dị ka electrolyte, Ọtụtụ mgbe sulfate, AC electrolysis.
Usoro agba agba
Usoro bụ: tinye akụkụ anodized aluminom alloy n'ime ihe ngwọta nwere agba agba, mgbe ahụ, ihe nkiri oxide pinhole adsorption agba na agba, usoro agba agba oxide ihe nkiri na ihe nkiri sulfuric acid kacha mma, ebe ihe eji esiji ihe nnọchianya bụ ammonium oxalate ferrous (edo edo edo edo edo) cobalt acetate (agba ọla) ihe nkiri cathodic oxide agba mgbe ọ dị mkpa iji mechie oghere ahụ, e nwere ụzọ abụọ bụ isi.

Ngwọta mkpuchi Organic
Mgbe cathodic oxidation na agba agba ọgwụgwọ nke aluminom, iji melite corrosion eguzogide na loading corrosion mmetụta, Enwere ike ịme ọgwụgwọ mkpuchi organic.
Ihe mkpuchi electrostatic
Wepu agba ahụ na nha dị mma wee fụọ ya n'elu ihe a ga-ekpuchi ka ọ bụrụ ihe mgbakwunye., n'ozuzu na-eme ka ihe agba agba na cathode mbụ, ma n'otu oge ahụ tinye voltaji 100KV DC na ihe a ga-ekpuchi dị ka cathode, A na-ahọrọ agba ahụ site na resin acrylic.
Ihe mkpuchi electrophoretic
Na aqueous ngwọta nke acrylic resin, A na-eji ihe nkiri oxide mee ihe dị ka cathode na electrolysis na-arụ ọrụ na voltaji 200V DC iji mee ka ihe nkiri oxide kpuchie ya na ihe nkiri mkpuchi organic.
