Ithayisi yinkqubo esetyenziselwa ukwenza ifilimu yealuminium oxide kumphezulu we-aluminium okanye iimveliso ze-Aluminium. Kubandakanya ukubeka imveliso ye-aluminium okanye i-Aluminium Alloy njenge-anode kwisisombululo se-electrolyte kwaye sisebenzise umbane wangoku ukwenza ifilimu yealuminium ox. I-Anodime iphucula ukumelana nokunganyangeki, ukunxiba ukunganyangeki, kunye neepropathi zokuhombisa zeeprofayili zeAluminium. Ngexesha lenkqubo ye-Autminise yeeProfayili zeAluminium, amanqaku aliqela aqhelekileyo anokwenzeka. Makhe siqonde oonobangela befilimu. I-Porrosion yezinto ezibonakalayo, ungcoliseko lokuhlamba, ukumisela izigaba zesibini ze-alloy, okanye iziphumo ze-ganjac nazo zonke zikhokelele kwiziphene ezibonakalayo. Zichazwe ngolu hlobo lulandelayo:
I-1.ICD okanye i-alkali etching
Ngaphambi kokuba kutonwe, izinto ze-aluminium zinokuchithwa ngotywala okanye i-alkaline yotywala, okanye zichaphazelekile yi-Acid okanye i-Alkaline fumes, ezikhokelela kwiindawo ezimhlophe ezisemgangathweni kumphezulu. Ukuba i-corrosion inzima, amabala amakhulu anokwenziwa. Kunzima ukumisela iliso elinqunu ukuba ingaba i-corrosion ibangelwa yi-acid okanye i-alkali, kodwa inokwahlula-hlula ngokuqaphela icandelo lomnqamlezo phantsi kwe-microscope. Ukuba amazantsi omgodi ajikeleze ngaphandle kokungakhathali phakathi komxhasi, kubangelwa yiAlkali ethambile. Ukuba ezantsi ayihambelani kwaye ihamba kunye nokungakhathaleli i-insosion, ngemingxunya enzulu, ibangelwa yi-acid ye-otid. Ukugcina okungafanelekanga kunye nokusingatha kumzi-mveliso kunokukhokelela kolu hlobo lokungabikho. I-acid fumes kwiarhente zokushicilela zekhemikhali okanye ezinye ii-acidic, kunye namagqwirha e-orgaric, yimithombo ye-acid ye-acid ye-otid. I-Alkali ye-Alkali ibangelwa kukusasazeka kwaye ichithe udaka, i-Ash, kunye noLwiline. Nje ukuba unobangela uzimiselweyo, ukomeleza ukuphathwa kweenkqubo ezahlukeneyo kumzi-mveliso kunokusombulula ingxaki.
I-2.atmospheric colososion
Iiprofayili ze-aluminium ziveze umoya onomswakama zinokuhlakulela amabala amhlophe, ezihlala zilungelelanisa ixesha elide ecaleni kwemigca yobumba. I-Atmospheric Souths ingekho ngokubanzi njenge-acid okanye i-alkali ethotha kwaye inokususwa ngeendlela zoomatshini okanye i-alkaline yokuhlamba. I-Atmospheric South Allrosion ayizizo i-PROOSTRY ingeyiyo indawo yokuhlala kwaye ithanda ukuba yenzeke kumphezulu othile, njengamanzi amaqondo obushushu apho amanzi amanzi ahlala khona ngokulula okanye kwimigangatho ephezulu. Xa i-Tomosmossion inzima kakhulu, icandelo elinqamlezileyo lemihlaba ethatyathiweyo libonakala ngathi amakhowa angenayo. Kule meko, i-alkaline yokuhlamba ayinakukwazi ukuyisusa amabala okudlala kwaye inokubenza bawakhulise. Ukuba i-Tomospheric South igqityiwe, iimeko zokugcina kumzi-mveliso kufuneka zihlolwe. Izixhobo ze-aluminium akufuneki zigcinwe kwiindawo ezinamaqondo obushushu aphezulu ukuthintela ukufundisa kwamanzi. Indawo yogcino kufuneka yome, kwaye amaqondo obushushu kufuneka abe njengeyunifomu kangangoko kunokwenzeka.
I-Corrosion yeThutyana (amabala amanzi)
Xa iphepha okanye ikhadibhodi libekwe phakathi kwezinto ze-aluminium okanye ezisetyenziselwa ukupakisha, kuthintela i-abrasion. Nangona kunjalo, ukuba iphepha liba ngumphunga, amabala okunyanzelwa avele kumphezulu we-aluminium. Xa i-corgocboard yekhadibhodi isetyenzisiwe, imigca eqhelekileyo ye-corrosion spots ivele kumanqaku okunxibelelana neBhodi eDityanisiweyo. Nangona iziphene ngamanye amaxesha zinokubonakala ngqo kumgangatho wealuminum, zihlala zibizwa emva kokuba i-Alkaline yokuhlamba kunye nokuthambisa. La mabala ngokubanzi anzulu kwaye kunzima ukususa ngeendlela zoomatshini okanye ukuhlamba i-alkaline. Iphepha (iBhodi) I-Colosion ibangelwa zii-acid ii-ocid, ubukhulu becala kunjalo, kunye ne-CL-, ezikhoyo ephepheni. Ke ngoko, usebenzisa iphepha (iBhodi) ngaphandle kwe-chlolorpider kunye nokuthintela ukungena kwamanzi ziindlela ezisebenzayo zokuthintela iphepha (iBhodi).
I-Frosion Foosion ye-Foosion (ekwabizwa ngokuba yi-Snowfrion Snosion)
Emva kokuhlamba i-Alkaline, iPomical Sholings, okanye i-SulFuric Acid, ukuba amanzi aqengqelekayo aqokelele ukungcola, kunokubangela iindawo ezinomgangatho. Ubunzulu bokungabikho kwe-inokolo. Olu hlobo lohlobo lwendalo lwenzeka xa amanzi okucoca angcoliseka kakhulu okanye xa inqanaba lokuhamba kwe-rinsing liphantsi. Ifana ne-crystal enekhephu enekhephu ngembonakalo, yiyo loo nto igama elithi "ikhephu lekhephu." Unobangela kukusabela phakathi kokungcola kwe-zinc kwi-aluminium kunye ne-SO42- kunye namanzi okucoca. Ukuba ukufundwa kwetanki elihlwempuzekileyo, Iziphumo ze-eganic zinokwenza esonge isiphene. Ngokutsho kwemithombo yamanye amazwe, xa umxholo we-ZN Alwal Alloty ungaphezulu kwe-0.015%, amanzi okucoca aphezulu kune-15 ye-PPM, olu hlobo losulelo lunokwenzeka. Sebenzisa i-nitric acid yokuthatha okanye ukongeza i-0.1% HNo3 kumanzi okucoca angayisusa.
5.Ucloride uCorrosion
Ubukho bexabiso elincinci le-chloride kwi-calfuric acid yokuhlamba inokukhokelela ekuphenduleni ukususwa. Inkangeleko yophawu yi-pits emnyama enzulu ye-Star, egxile kakhulu kwimiphetho kunye neekona ze-odriece okanye kwezinye iindawo ezinoxinano lwangoku. Iindawo ezimbi zokuhamba-mbi zingenayo ifilimu engathatyathwayo, kunye nobungqingqwa befilimu kwindawo eseleyo "eqhelekileyo" ziphantsi kunexabiso elilindelweyo. Umxholo wetyuwa ephezulu kumanzi empompo yeyona mthombo ophambili wokungcola kwibhafu.
6.Galvanic Sorion
Kwitanki enamandla (ukuthambisa okanye ukuthambisa kombala), iziphumo ze-etanic phakathi komsebenzi kunye netanki (itanki yentsimbi), okanye imiphumo yetanki engasebenziyo kwitanki engasebenziyo (i-rinsing okanye iphazamisayo okanye iphazamisayo okanye iphazamisayo okanye iphazamisayo okanye iphazamise.
