Lisebelisoa tsa aluminiumba fumane sebaka sa bona e le e 'ngoe ea lisebelisoa tse sebetsang ka ho fetisisa indastering ea sejoale-joale. Ho tloha sebakeng sa sefofane ho isa ho tsa kaho, tlhaho ea bona e bobebe le e tšoarellang e etsa hore e be tsa bohlokoa haholo. Leha ho le joalo, e 'ngoe ea litšobotsi tsa bona tse ikhethang ke tsa bonakhanyetso ea kutu. Empa ke eng e fang li-alloys tse matla a tsona a ho mamella maemo a thata? Ha re hlahlobeng mahlale le lits'ebetso tse ka morao ho corrosion resistance ea li-alloys tsa aluminium le hore na thepa ena e tsoela liindasteri molemo joang lefatšeng ka bophara.
Ho utloisisa Corrosion: Phephetso e Tloaelehileng bakeng sa Metals
Corrosion e etsahala ha litšepe li sebetsana le maemo a tikoloho joalo ka oksijene, mongobo, kapa lik'hemik'hale, tse lebisang ho senyeha. Bakeng sa litšepe tse ngata, ts'ebetso ena e fokolisa thepa ka nako, e ama ts'ebetso ea eona le nako e telele. Li-alloys tsa aluminium, leha ho le joalo, li arohane ka lebaka la bokhoni ba tsona ba tlhaho ba ho hanela ho bola.
Ho fapana le tšepe, e etsang mafome ha e na le oxidized, aluminium e etsa lera le sireletsang la aluminium oxide. Filimi ena e tšesaane, e sa bonahaleng e sebetsa e le mokoallo, e sireletsang tšepe e ka tlaase ho pepeseha ho eketsehileng.
Mahlale a ka Mora ho Corrosion Resistance ka Aluminium Alloys
Lekunutu la ho hanyetsa ho bola ha aluminium alloys le ka har'a thepa ea bona ea lik'hemik'hale le sebopeho sa alloy:
1.Aluminium Oxide Layer Formation
Ha aluminium e kopana le moea, e kopana le oksijene ho etsa aluminium oxide (Al2O3). Lera lena le thata ka mokhoa o ikhethang, le itokisa, 'me ha le sebetse. Esita le haeba e hahiloe kapa e senyehile, lesela la oxide le tsosolosoa kapele, le boloka tšireletso ea tšepe.
2.Alloying Elements le Karolo ea Tsona
Ho eketsa lintho tse kang magnesium, silicon, kapa zinki ho ntlafatsa ho thibela kutu ea aluminium ka ho fetola sebopeho le ts'ebetso ea eona. Mohlala:
•Li-alloys tse nang le magnesium: E loketse libaka tsa leoatle ka lebaka la ho hanyetsa ha tsona ho matla ha metsi a letsoai.
•Li-alloys tse thehiloeng ho silicon: Hangata e sebelisoa likarolong tsa likoloi bakeng sa ho ntlafatsa ho hanyetsa ho apara.
3.Mokhoa oa Passivation
Li-alloys tse ngata tsa aluminium li feta passivation, phekolo ea lik'hemik'hale e matlafatsang lesela la oxide, e netefatsang khanyetso ea nako e telele libakeng tse mabifi tse kang maemo a acidic kapa alkaline.
Lisebelisoa tsa 'Nete tsa Bophelo tse Bontšang Khanyetso ea Corrosion
Li-alloys tsa aluminium ke mokokotlo oa liindasteri tse ngata, ka lebaka la tlhaho ea tsona e sa bolaeeng ke kutu. Mehlala e seng mekae ke ena:
•Indasteri ea Sepakapaka: Likarolo tsa lifofane li tlas'a maemo a phahameng a feteletseng le maemo a leholimo. Lisebelisoa tsa aluminium li fana ka nako e telele le ho hanyetsa mongobo, li etsa hore e be tse loketseng bakeng sa fuselage le mehaho ea mapheo.
•Kaho: Liforeimi tsa lifensetere, marulelo, le likoahelo tse entsoeng ka metsoako ea aluminium li ka mamella lilemo tsa ho pepesehela pula le khanya ea letsatsi ntle le ho senyeha ho hoholo.
•Likopo tsa Marine: Likepe, likepe le liforomo tse ka thōko ho leoatle li itšetlehile ka lisebelisoa tsa aluminium ho hanela liphello tse senyang tsa metsi a letsoai, ho lelefatsa bophelo ba tsona ba ts'ebetso.
•Tsa elektroniki: Li-alloys tsa aluminium tse thibelang ho bola li sireletsa likarolo ho tsoa tšenyong ea tikoloho, li netefatsa ho ts'epahala ho lisebelisoa tse kang li-smartphone le lilaptop.
Thuto-pale: Lisebelisoa tsa Aluminium ho Boenjiniere ba Marine
Nahana ka tšebeliso ea li-alloys tsa aluminium-magnesium ha ho etsoa likepe. Likepe tsa khale tsa tšepe li na le mafome, li hloka tlhokomelo e pharaletseng le liphahlo tse sireletsang. Leha ho le joalo, li-alloys tsa aluminium-magnesium li hanela kutu ka tlhaho, li fokotsa litšenyehelo tsa tlhokomelo le ho lelefatsa nako ea bophelo ea likepe tsa metsing.
Mohlala o mong o hlahelletseng ke oa kaho ea likepe tse lebelo le holimo. Ho hanyetsa kutu ha aluminium ha ho matlafatse ho tšoarella feela empa hape ho fokotsa boima ba 'mele, ho ntlafatsa ts'ebetso ea mafura-e leng katleho bakeng sa basebetsi le tikoloho.
Hobaneng ha Corrosion Resistance e le Bohlokoa bakeng sa Ts'ebetso
Nako e telele ea bophelo le litlhoko tse fokolang tsa tlhokomelo ea li-alloys tsa aluminium li kenya letsoho ho tsitsitseng. Li fokotsa tlhoko ea ho nchafatsoa le ho lokisoa khafetsa, ho baballa lisebelisoa le ho fokotsa litšila. Ho feta moo, aluminium e sebelisoa hape haholo, e boloka thepa ea eona e sa jeng le ka mor'a hore e sebelisoe khafetsa.
Liindasteri tse batlang litharollo tsa tikoloho li ntse li fetohela ho li-alloys tsa aluminium bakeng sa bokhoni ba tsona ba ho kopanya ts'ebetso le botsitso.
Ho Khetha Lisebelisoa tsa Aluminium bakeng sa Merero ea Hau
Ho utloisisa maemo a itseng a tikoloho eo thepa ea hau e tla tobana le eona ho bohlokoa ha u khetha motsoako o nepahetseng oa aluminium. Hore na o ntse o rala kaho ea lebopo, boqapi ba sepakapaka, kapa boenjineri ba leoatleng, lisebelisoa tsa aluminium li fana ka nako e telele e ke keng ea lekanngoa le ho hanyetsa ho bola.
