Aluminium nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche n'ihi ịdị arọ ya, ịdịte aka ya na nguzogide corrosion dị mma. Otú ọ dị, ọ naghị echebe ya kpam kpam na corrosion. N'isiokwu a, anyị ga-atụle ụdị nke corrosion na-emetụta ya, na ụzọ iji gbochie corrosion.
Kedu ihe kpatara corrosion aluminom ji dị njọ?
A na-ahọrọ aluminum na ngwa dị iche iche n'ihi njupụta ya dị ala, na-eme ka ọ dị ọkụ karịa ọla ndị ọzọ dị ka ígwè. A makwaara ya maka ezigbo ihe ọkụkụ na ọkụ eletrik. Otú ọ dị, ọ na-enwe ike ịnweta ụdị corrosion dị iche iche, gụnyere pitting, galvanic, na inter-granular corrosion. Nrụrụ aka na-apụta mgbe obere olulu na-etolite n'elu igwe n'ihi ikpughe na gburugburu ebe ike. Galvanic corrosion na-eme mgbe aluminom na-abanye na kọntaktị na ọla ndị yiri ya na ọnụnọ nke electrolyte, na-emepụta cell corrosion. Inter-granular corrosion na-emetụta aluminom alloys, na-ebelata ihe onwunwe n'akụkụ oke ọka.
Ndụmọdụ maka otu esi ezere corrosion nke pitting
Iji gbochie corrosion aluminom, mkpuchi mkpuchi na-arụ ọrụ nke ọma.Anodizing, eserese, na mkpuchi ntụ ntụna-enye ihe mgbochi n'etiti ígwè na gburugburu ebe obibi ya na-emebi emebi, na-egbochi mmiri na ihe ndị ọzọ na-emebi emebi iru n'elu. Iji ncha na mmiri dị nro na-ehicha mgbe niile nwere ike wepu unyi na unyi, na-ezere ngwangwa corrosion. Ekwesịrị ịzere kemịkalụ siri ike na ndị na-ehicha ihe n'ihi na ha nwere ike imebi oyi akwa ahụ.
Ichebe aluminom site na kọntaktị kpọmkwem na ọla ndị yiri ya na-ebelata ohere nke corrosion galvanic. Enwere ike iji ihe mkpuchi dị ka plastik ma ọ bụ gaskets rọba gbochie kọntaktị ozugbo n'etiti aluminom na ọla ndị ọzọ. Ọzọkwa, ịchịkwa ikpughe na gburugburu ebe ndị na-emebi emebi dị oké mkpa. Ime usoro ikuku ikuku na iru mmiri kwesịrị ekwesị nwere ike ibelata oke mmiri na ọnụnọ kemịkalụ ma ọ bụ gas na-emebi emebi.
N'ikpeazụ, ọ bụ ezie na aluminom nwere ọtụtụ uru, ọ na-adaba na corrosion. Pitting, galvanic, na inter-granular corrosion bụ ụdị nkịtị na-emetụta aluminum. Itinye mkpuchi mkpuchi, idowe ịdị ọcha, izere kọntaktị na ọla ndị yiri ya, na ịchịkwa ikpughe na gburugburu ebe ndị na-emebi emebi bụ ụzọ mgbochi dị irè.

Ọ bụrụ na ị nwere ajụjụ ndị ọzọ gbasara igbochi corrosion aluminum, nweere onwe gịkpọtụrụ anyịịmụtakwu. Mgbochi bụ atụmatụ dị mma mgbe niile karịa imegide corrosion ozugbo ọ batara.
