Umphumela wokwelashwa okuvuthayo kwezingxenye ze-aluminium

Kuyaziwa ukuthi i-aluminium ne-alloys yayo oxidize emoyeni, futhi i-oxide yefilimu ye-oxide eyenziwe ngokwemvelo ebusweni bezingxenye ze- aluminium ezinama -aromphoous, ezizokwenza ingaphezulu lezingxenye zalo ze-aluminium ukuze zilahlekelwe yi-luster yayo yasekuqaleni, yize le filimu yayo ye-oxide yemvelo izovikela ingaphezulu lezinhlansi ze-aluminium ezifakwe emkhakheni kodwa lincane kakhulu, licishe libe ngu-4 kuye kwayi-5 nm, futhi line-porolity enkulu nezindawo ezingezinhle zemishini. Akunakuvimbela ngempumelelo ukugcwala okuqhubekayo kwezingxenye ze- aluminium ezifakwe kwabezindaba ezahlukene emkhathini.

Ngemuva kokufaka i-anodizing, ingaphezulu lezingxenye ze-aluminium ezisetshenziswayo zingathola ungqimba lwefilimu eliminyene (kusuka kumashumi ama-micrometers kuya ngisho namakhulu ama-micrometers) akhulu kakhulu kunefilimu le-oxide yemvelo. Le filimu ye-oxide ye-anificial axifialias ifakwa ngaphansi kokwelashwa kokubekwa uphawu. Ifilimu ye-Amorphous Oxide iguqulwa ibe yifilimu ye-crystalline oxide, futhi ama-pores nawo avale. Ngakho-ke, i-bloss forver yensimbi ihlala ingashintshiwe, futhi ukumelana nokugqwala namandla okusebenza athuthukile. Ngemuva kokudaya, ukubukeka okuhlobisa kungatholakala futhi. Njengoba izingxenye ze- aluminium ezinemishini zinezici eziningi ngemuva kokungenwa, inqubo ye-aluminium anodizing isetshenziswa kabanzi ekwelashweni kwezingxenye ze- aluminium ebekiwe . Izicelo embonini zingahle zihlukaniswe ngokulinganayo ezinhlotsheni ezilandelayo.

. Kungakhathalekile ukuthi i-oxide filimu etholwe kwikhambi le-acid le-sulfuric, i-chromic acid isixazululo kwinqubo ejwayelekile, ukumelana nokugqwala kunhle kakhulu, njengembiza ye-aluminium yansuku zonke, imbiza, umshini wokuwasha umshini, nokunye.

. Imibala ehlukahlukene ekhanyayo negqamile namaphethini angatholakala kwifilimu ye-oxide. Ukubonakala kwezinqubo ezintsha ezimbalwa njenge-oxidation amaningi ye-oxidation, amaphethini okuqhuma iziqhumane, ukudluliselwa kokuphrinta kokuphrinta kwe-oxidized offset, i-oxidation ye-porcelain, njll. Yenza ukubonakala kwezingxenye ze- aluminium ezinhle kakhulu. Lesi singqimba sefilimu yombala siyingqimba yokuhlobisa kanye nongqimba olulwa nokulwa nokulwa.

(3) njengesendlalelo sokugqoka esigqokile ungqimba lwefilimu. Isetshenziswa ngempumelelo kwimibandela yokusebenza eMnyangweni Wombuso futhi inezimpawu zokuthambisa nokudla, njengezixhumanisi zenjini namapayipi ezimoto kanye nogandaganda.

(4) Njengoye ungqimba olufaka ugesi Lesi sici sinokubaluleka okuthile okusebenzayo njengokufakelwa kukagesi futhi singasetshenziswa njenge-capacitor. Lesi sici sisetshenzisiwe singasetshenziswa nakwezinye izinto zikagesi.

. Ungqimba we-anodised we-phosphoric acid lungasetshenziswa njengesendlalelo esingaphansi ethafeni le-aluminium.
