Aluminiumis e sebelisoa haholo liindastering tse fapaneng ka lebaka la boima ba eona bo bobebe, ho tšoarella nako e telele, le khanyetso e ntle ea kutu. Leha ho le joalo, ha e sireletsehe ka ho feletseng ho bola. Sehloohong sena, re tla tšohla mefuta ea kutu e e amang, le mekhoa ea ho thibela ho bola.

Hobaneng ha Aluminium Corrosion e le Mpe?

Aluminium e ratoa lits'ebetsong tse fapaneng ka lebaka la letsoalo le tlase, e etsa hore e be bobebe ho feta litšepe tse ling joalo ka tšepe. E boetse e tsejoa ka thepa ea eona e babatsehang ea mocheso le motlakase. Leha ho le joalo, e ka hlaseloa habonolo ke mefuta e fapaneng ea kutu, ho kenyelletsa le pitting, galvanic, le inter-granular corrosion. Pitting corrosion e etsahala ha mekoti e menyane e hlaha holim'a tšepe ka lebaka la ho pepesehela tikoloho e mabifi. Galvanic corrosion e etsahala ha aluminium e kopana le litšepe tse sa tšoaneng ka pel'a electrolyte, ho theha sele ea kutu. Inter-granular corrosion e ama li-alloys tsa aluminium, e fokolisa thepa e haufi le meeli ea lijo-thollo.

Litlhahiso tsa ho qoba ho corrosion ka likoti

Ho thibela kutu ea aluminium, liphahlo tse sireletsang li sebetsa haholo.Anodizing, ho penta le ho roala phofofana ka mokoallo pakeng tsa tšepe le tikoloho ea eona e senyang, ho thibela mongobo le lisebelisoa tse ling tse senyang ho fihla holimo. Ho hloekisa khafetsa ka sesepa le metsi ho ka tlosa litšila le litšila tse bokelletsoeng, ho qoba ho potlaka ha kutu. Lik'hemik'hale tse bohale le lisebelisoa tse hloekisang li lokela ho qojoa kaha li ka senya lera le sireletsang.

Ho sireletsa aluminium hore e se kopane ka ho toba le litšepe tse sa tšoaneng ho fokotsa kotsi ea galvanic corrosion. Lisebelisoa tse sireletsang tse kang polasetiki kapa li-gaskets tsa rabara li ka sebelisoa ho thibela ho kopana ka ho toba pakeng tsa aluminium le lisebelisoa tse ling. Ho feta moo, ho laola ho pepeseha ha maemo a senyang ho bohlokoa. Ho kenya tshebetsong mehato e nepahetseng ya moya le taolo ya mongobo ho ka fokotsa maemo a mongobo le boteng ba dikhemikhale kapa digase tse senyang.

Qetellong, le hoja aluminium e na le melemo e mengata, e kotsing ea ho bola. Pitting, galvanic, le inter-granular corrosion ke mefuta e tloaelehileng e amang aluminium. Ho sebelisa litlolo tse sireletsang, ho boloka bohloeki, ho qoba ho kopana le litšepe tse sa tšoaneng, le ho laola ho pepeseha ha libaka tse senyang ke mekhoa e sebetsang ea thibelo. Ka ho kenya ts'ebetsong mehato ena, nako ea bophelo le ts'ebetso ea aluminium e ka eketsoa, ​​​​ho netefatsa hore e tsoela pele ho sebelisoa lits'ebetsong tse fapaneng.

Haeba u na le lipotso tse ling mabapi le ho thibela kutu ea aluminium, ikutloe u lokolohile hoiteanye le ronaho ithuta haholoanyane. Thibelo kamehla ke leano le betere ho feta ho sebetsana le corrosion hang ha e qala.
