Aluminium ndiyo yechipiri pakukura simbi papasi, uye nekuda kwehunhu hwayo hwakanaka, ndiyo imwe yesimbi dzinoshandiswa zvakanyanya nhasi. Nokudaro, zvinobatsira kunzwisisa mamiriro ezvinhu anopfupisa hupenyu hwesimbi idzi.

Kuora kwesimbi chero ipi zvayo kuchakanganisa zvikuru simba rayo rekushanda, uye mumamiriro ezvinhu akaipisisa zvinotungamirira kukuvadzwa kwemaitiro, zvakadai sekutsemuka, kutsemuka kwechidimbu uye kukundikana kwezvinhu zvakakwana.

Chii chinonzi aluminium corrosion? Aluminium corrosion inoreva kuparara zvishoma nezvishoma kwemaaruminiyamu mamorekuru kuita okisidhisi, nekudaro ichidzikisa chimiro chayo chemuviri nemakemikari. Muchidimbu, aruminiyamu isimbi inoshanda, asi zvakare isimbi inongoshanda.

Mhando dzealuminium corrosion
Atmospheric corrosion
Iyo yakajairika fomu yealuminium corrosion. Kuratidzwa kwealuminium kune zvechisikigo zvinhu zvinogona kukonzera ngura mumhepo. Sezvo zvichigona kuitika munzvimbo zhinji, ngura yemuchadenga inoumba chikamu chikuru chekukuvara kwealuminium kunokonzerwa nemhando dzese dzekuora munyika.

Kuora kwemagetsi
Galvanic corrosion, inozivikanwawo se dissimilar metal corrosion, inokanganisa aluminium mumuviri kana kuburikidza nemagetsi akabatana nesimbi dzinokosha. Iyo inoyevedza simbi inogona kunge iri chero simbi ine yakaderera reactivity pane aruminiyamu.

Pitting
Pitting corrosion is the surface corrosion phenomenon yealuminium metal, iyo inoratidzwa nemakomba maduku (makomba) pamusoro. Kazhinji, ma dimples aya haakanganisa kusimba kwechigadzirwa. Asi, iyi inyaya yekunaka, asi kana chitarisiko chepamusoro chakakosha, chinogona kukonzera kukundikana.

Crevice corrosion
Crevice corrosion imhando yenzvimbo yecorrosion process muzvinhu. Zvinhu zvinopindirana kana kukanganisa dhizaini zvinogona kutungamira pakuumbwa kwemagapu. Nekuda kweizvozvo, kuunganidza mvura yegungwa mumasaga aya kunogona kukonzera kukoromoka kwemukaha.

Exfoliation corrosion
Exfoliation corrosion imhando yakakosha ye intergranular corrosion mune aruminiyamu alloys, ine yakajeka inotungamira chimiro. Izvi zvinonyanya kuoneka muzvigadzirwa zvealuminium zvakambopisa kana kutonhora.
