Nghota oxidion na corrosion
Oxiding bụ mmeghachi kemịkalụ nke na-eme mgbe ihe na-eweta oxygen. N'ihe banyere ọla, usoro a na-ebute corrosion, nke bụ ndakpọ nwayọ nke igwe n'ihi mmeghachi omume kemịkal na gburugburu ya. Mitals oxidize mgbe ekpughere mmiri, ikuku ma ọ bụ kemịkal, na-akpụ oxide. Dịka ọmụmaatụ, iron oxidizes iji mepụta nchara (iron oxide), nke nwere ike imebi ọla mgbe.

Ngwakọta oxidation, dị ka acid, nnu, na gas, mee ka usoro corrosion mee ngwa ngwa. Mgbe ihe ndị a batara na kọntaktị ọla, ha na-amalite ma ọ bụ mee ka mmeghachi omume oxiding. Dịka ọmụmaatụ, acdrochloric acid bụ ike siri ike karịsịa corrode ọla dị ka steel na aluminom.
