A na-ekewa mkpuchi mkpuchi mgbochi n'ime ihe mkpuchi mgbochi na-emekarị na mkpuchi mgbochi corrosion dị arọ, nke bụ ihe mkpuchi dị mkpa na mkpuchi agba.Mgbochi mgbochi corrosion nke ọdịnala na-ekere òkè n'ịgbochi mmebi nke ọla n'okpuru ọnọdụ izugbe ma chebe ndụ ọrụ nke ọla ndị na-abụghị ígwè;A na-atụnyere ihe mkpuchi na-eme ka ọ dị arọ nke na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-adịghị mma, nke a na-etinye na gburugburu ebe obibi siri ike ma nwee ikike nke ụdị mkpuchi mgbochi nke na-enweta ogologo oge nchebe karịa ihe mkpuchi na-eme ka ọ dị ogologo.Ụkpụrụ mgbochi corrosion nke mkpuchi mgbochi corrosion izugbe dị na ntụziaka nke kemistri, physics na electrochemistry.Nke a bụ nkọwa zuru ezu:
1. Ụkpụrụ kemịkal nke mgbochi corrosion
Ụkpụrụ kemịkalụ nke mgbochi corrosion bụ iji wepụ ihe ndị na-emerụ emerụ nke acid-base n'ime ihe ndị na-anọpụ iche na ndị na-adịghị emerụ ahụ iji chebe ihe ndị dị na mkpuchi mgbochi na-emebi ihe.A na-agbakwunye ụfọdụ ogige amphoteric, dị ka aluminom hydroxide, barium hydroxide na zinc oxide, na mkpuchi mgbochi nchara.Ihe ndị a nwere ike ime ngwa ngwa na acid na alkali emerụ ihe iji nweta mmetụta mgbochi corrosion.

2. Ụkpụrụ anụ ahụ nke mgbochi corrosion
Ụkpụrụ anụ ahụ nke mgbochi corrosion bụ ikewapụ ihe a na-echebe site na ihe ndị na-emerụ emerụ na mpụga nke nwere mkpuchi mgbochi.Ụkpụrụ anụ ahụ nke agba mgbochi nchara bụ iji ihe na-emepụta ihe nkiri na-emepụta ihe nkiri iji nweta nnukwu mkpuchi mgbochi iji wepụ mmebi nke mmetụta mgbochi corrosion na ihe nchebe.Dịka ọmụmaatụ, agba na mmanụ nwere ndu nwere ike ịmepụta ncha ndu iji hụ na mkpuchi mgbochi corrosion The njupụta.

3. Mmetụta electrochemical nke mgbochi corrosion
The electrochemical mmetụta nke mgbochi corrosion na-ezo aka na mgbakwunye na nke ụfọdụ pụrụ iche bekee na-emegide nchara agba, nke mere na mgbe mmiri na oxygen gafere mgbochi nchara agba, ha ga-emeghachi omume na-etolite mgbochi corrosion ion, passivating elu nke. ọla dị ka ígwè, ma si otú ahụ gbochie ion ígwè.Mgbasa, iji nweta nzube nke mgbochi corrosion, ihe na-emekarị nke ihe a pụrụ iche bụ chromate.

Ebe ntinye nke mkpuchi mgbochi corrosion gụnyere akụkụ ise ndị a:
