Akụkọ

Ogologo oge ole ka aluminom ga-agbaze ma mebie mgbe ejiri ya?
Akụkụ bụ isi nke aluminom bụ aluminom na obere ego nke ihe ndị na-emepụta ihe.Ụfọdụ ndị na-eche na aluminum adịghị mfe oxidize n'ihi na e nwebeghị obere mgbanwe na agba.N'ezie, aluminom bụ ígwè na-arụsi ọrụ ike, dị mfe oxidize karịa ígwè.Ihe kpatara na a naghị ahụ ya anya bụ n'ihi na aluminom oxide kpụrụ mgbe oxidation na-enweghị agba na nghọta.Na nke a oyi akwa nke oxide film kewapụrụ esịtidem aluminum na ikuku kọntaktị, n'ihi ya, ọ ga-anọgide na-oxidize, ma si otú na-echebe aluminum mkpụrụ.Ya mere aluminum na-adịgide adịgide ọbụna na-enweghị ọgwụgwọ elu.
Ma ihe nkiri oxide abụghị ihe a na-apụghị imeri emeri, aluminum oxide na-arụ ọrụ na acid na alkali, na gburugburu ebe obibi na ikuku na-emebi emebi, a na-ebibi ihe nkiri oxide ngwa ngwa, na-eme ka corrosion nke aluminom substrate, mmebi.Ọ bụrụ na a na-eji ya eme ihe n'èzí, ikpughe anyanwụ, na mmiri ozuzo acidic ga-eme ka corrosion nke aluminom dịkwuo ngwa.Ya mere, ogologo oge profaịlụ aluminum ga-oxidize na corrode mgbe ejiri ya na-adaberekwa na gburugburu ebe obibi na ọgwụgwọ elu ya.The elu ọgwụgwọ nke aluminum profaịlụ na-agụnye anodic oxidation, electrophoresis, spraying, electroplating, wdg Anodic oxidation bụ usoro electrochemical nke na-etolite ihe artificial oxide film n'elu aluminum profaịlụ, nke bụ ukwuu thicker karịa eke kpụrụ oxide film na ọ bụ. na-eguzogide corrosion ọbụna n'èzí siri ike na gburugburu ebe obibi, na conservative ọrụ ndụ nwere ike iru 25 afọ.
