Anooding ni inzira ikoreshwa mugukora film oxide ya aluminium hejuru ya aluminium cyangwa aluminium alloy bikomoka. Harimo gushyiramo aluminium cyangwa aluminium ibicuruzwa nka anode mubisubizo bya electrolyte no gushyiramo amashanyarazi kugirango ukore firime ya aluminium. Anodhing itezimbere ihohoterwa rishingiye ku ruswa, yambara kurwanya, n'imitungo idahwitse ya aluminium. Mugihe cyo kuvura uburyo bwumugaragaro aluminium, ibintu byinshi bihuriweho bishobora kubaho. Reka mubyukuri twumve cyane ibitera ibitera inenge. Rubintu yibintu, kwanduza, kugwa kwa alloy ibyiciro bya kabiri, cyangwa ingaruka za galvanic zose zishobora kuganisha ku nenge zabonetse. Basobanuwe ku buryo bukurikira:
1.acide cyangwa alkali esching
Mbere yo guhuza, ibikoresho bya aluminium birashobora gukonja na aside cyangwa alkaline, cyangwa bigira ingaruka kuri aside cyangwa imyotsi ya alkaline, bikavamo ahantu heza hizewe hejuru. Niba ruswa ari ahantu hanini cyane, ibibara binini birashobora gukora. Biragoye kumenyana n'amaso yambaye ubusa niba urusaku rwatewe na aside cyangwa alkali, ariko birashobora gutandukanywa byoroshye nukureba kwambukiranya igice cyangirika munsi ya microscope. Niba hepfo yurwobo ruzengurutse kandi nta ruswa ivanze, iterwa na alkali esching. Niba hepfo ari bidasanzwe kandi biherekejwe no guhagarika ibicuruzwa bivanze, hamwe nimboga ndende, biterwa na aside. Ububiko budakwiye no gukoresha mu ruganda birashobora kandi gushikana kuri ubu bwoko bwa ruswa. Acide avuye mu bakozi bo muri chimique chimique cyangwa andirimbo acide, kimwe na devloric des orloric, ni inkomoko ya aside isching. Ething isanzwe iterwa no gutatanya no gupfukama kwa minisiteri, imiyoboro ya sima, na alkaline. Iyo impamvu imaze kwiyemeza, gushimangira imicungire yimikorere itandukanye muruganda irashobora gukemura ikibazo.
2.Kuringaniza
Umwirondoro wa Aluminium uhura numwuka wishure ushobora guteza imbere ibibara byera, akenshi bihuza igihe kirekire kumurongo wa mold. Ibijumba byikirere muri rusange ntabwo bikabije nka aside cyangwa alkali esching kandi birashobora gukurwaho nuburyo bwa mashini cyangwa gukaraba alkaline. Ibijumba byikirere birahari cyane kandi bikunda kugaragara ku buso bumwe, nko mu bushyuhe bwo hasi aho imyuka y'amazi aringaniye cyangwa hejuru. Iyo kugabanuka kwikiyiro bikabije, umusaraba wibintu byo kwisiga bigaragara nkibihumyo byahinduye. Muri iki kibazo, gukaraba alkaline ntibishobora gukuraho ibibara kugirango bishobore kubabaza. Niba ruswa yo mu kirere igenwa, imiterere yo kubika mu ruganda igomba kugenzurwa. Ibikoresho bya Aluminium ntibigomba kubikwa ahantu hamwe nubushyuhe buke cyane kugirango wirinde imyuka y'amazi. Agace k'ububiko kagomba kwuma, kandi ubushyuhe bugomba kuba bumeze nkimyambaro ishoboka.
3.Gupakiro (ibibanza by'amazi)
Iyo impapuro cyangwa ikarito zishyizwe hagati yibikoresho bya aluminium cyangwa bikoreshwa mugupakira, birinda Aburasi. Ariko, niba impapuro zihindutse, ahantu nyaburanga kugaragara hejuru ya aluminium. Iyo ikarito ikarirwa ikoreshwa, imirongo isanzwe yibibanza byangiza bigaragara muburyo bwo guhura ninama yubukorikori. Nubwo inenge zishobora rimwe na rimwe kugaragara hejuru yubuso bwa aluminium, akenshi bivugwa cyane nyuma yo gukaraba alkaline no mu kayira. Ibibanza muri rusange birimbitse kandi biragoye gukuraho muburyo bwa mashini cyangwa gukaraba alkaline. Impapuro (Ikibaho) ruswa iterwa na aside ion, cyane cyane kuri 42- na cl-, biboneka mu mpapuro. Kubwibyo, ukoresheje impapuro (ikibaho) udafite chlorides na sulfate kandi wirinze kwinjira mumazi nuburyo bwiza bwo kwirinda impapuro (ikibaho) ruswa.
4.Gukoresha ibiryo by'amazi (bizwi kandi nka ruswa)
Gukaraba alkaline, imiti yo gukosora imiti, cyangwa gutoranya ulike, niba amazi yogeje arimo umwanda, birashobora kuvamo inzara cyangwa ibibara bikaze hejuru. Ubujyakuzimu ni buke. Ubu bwoko bwa ruswa bubaho mugihe amazi yoza yanduye cyane cyangwa mugihe igipimo cyurugendo rwuzuye ko cyuzuye. Birasa na kristu ya shelegi hagaragara, bityo izina "urubura rukabije." Impamvu ni reaction iri hagati ya Zinc muri aluminium na Somunum na Souminum na Sol2- kandi bitwaza amazi meza. Niba ibijyanye na tank ari bibi, ingaruka z'ibigegali zirashobora kwiyongera kuri iyi sinere. Nk'uko ingingo z'amahanga zibitangaza, iyo ibikubiye muri ZN muri aluminium biruta 0.015%, Clicy, mu mazi yoza arenga 15 ppm, ubu bwoko bw'urugero rushobora kubaho. Gukoresha acide ya nitric yo gutora cyangwa kongeramo 0.1% HNO3 kumazi yoza arashobora kuyikuraho.
5.Hlodie
Kubaho kw'igice gito cya chloride mu mvugo ya sulfuric acdioning irashobora kandi kuganisha ku gukubita ruswa. Kugaragara biranga nibyobo byirabura byinshi byinyenyeri, byibanda cyane kumpande hamwe nimpande zakazi cyangwa mubindi bice bifite ubucucike bwisumbuye. Ahantu ho gushinga imiyoboro, hamwe nubunini bwa firime muri "bisanzwe" bisigaye bitarenze agaciro kateganijwe. Umunyu mwinshi mumazi ya robine niyo soko nyamukuru yitariki yo kwiyuhagira.
Uruganda
Mu tank ingufu (Anooding cyangwa Electrolyting Ibara), ingaruka za galvanic hagati yumurimo hamwe na tank (cyangwa ingaruka za tank yazimye mu tank idafunzwe (yoza cyangwa ngo itemba cyangwa kongera indorerwamo.
