Anodizing: aluminium iyo Alloys ay waxaa loo isticmaalaa sida anodes, oo keeni ama graphite waxaa loo isticmaalaa sida cathodes. In fiirsashada gaar ah (sida acid sulfuric, oxalic acid, chromic acid, iwm) xal tabinta, iyada oo danab codsatay iyo saamaynta hadda korontada, oo dhumucdiisuna waxay gaar ah (8-12um) lakabka waxaa la aasaasay on dusha sare ee shirkadda, oo wuxuu leeyahay sifooyin farsamoyaqaanka wanaagsan, qalbi engegnaantooda aawadeed, iska caabin ah daxalka, xirtaan iska caabin ah, ningax, adsorbability iyo wixii la mid ah.
1. maaddooyinka: maaddooyinka dareeraha organic, biyo ku salaysan nadaafadda emulsification maaddooyinka wakiilka, maaddooyinka electrochemical.
2. Chemical qiraan: dheeraad ah ay ka saareen uus on dusha sare ee aluminium iyo daawaha la phosphoric acid, oo ay ka saareen xabagta filimka dabiiciga ah oo korka ka mid ah daawaha aluminium, si substrate aluminium la kulmin si loo fududeeyo anodization xiga. Isla mar ahaantaana, nadiifinayo ayaa sidoo kale waxay leedahay saameyn ah ee Nigeria, taas oo sii simi karaa dusha sare ee workpiece ka dib markii sandblasting, iyo dareen taabasho dusha waa ka wanaagsan.
3. fiiqma filim madow: Ka dib markii phosphorylation, filim madow-cawlan (biraha sida copper, nickel, manganese, iron, Silicon, iwm, taas oo ah beelaya in phosphoric acid) ayaa weli on dusha sare ee workpiece ah, ka dibna lagu daaweeyaa nitric acid.
4. qayilo: Geedi socodka ah ee la xirrira filim xabagta ku soo saarka ah aluminium (anode) hoos tallaabo ah ee hadda an la dabaqay hoos elektrolytka u dhigma iyo xaalado gaar ah s. Anodic qayilo, haddii aan la cayimay, sida caadiga ah waxay ka dhigan tahay Anodizing sulfuric acid.
5. dyeing: dyeing waa in la sameeyaa si degdeg ah ka dib markii anode oo aan aad u dheer. Ka dib markii lagu qayilo, si taxadar leh raaci off acid ee haraaga ah biyo qabow (fogaado kaca heerkulka iyo xuub waxaa si toos ah waxaa laga shaabadeeyey).
6. Daboolayo: heerkulka sare shaabadood biyo karkaraya daloolada ah, iyo alumina isku daraa la taagoo biyo si ay u sameeyaan hydrates, la xirrira kiristaalo.
7. qallajinta: Place sheyga in foorno leh heerkulka foornada dhigay at 70 ° C. heerkulka quwad waa in aanay noqon mid aad u sareeya, haddii kale filimka waa mid u nugul dildilaaca. Ka hor inta lagu dhaqo, waa in la maydhay biyo kulul si ay u kordhiyaan heerkulka workpiece si fogaado in crack sababa workpiece aad u qabow isagoo.
