Kedu ka igwe si egbochi nchara?

Mgbe ngwaahịa igwe na-ekpuchi ikuku na ikuku mmiri ruo ogologo oge, ha na-adị mfe ịnweta corrosion oxidative, na-ebute nchara n'elu ígwè.

Iji dozie nsogbu nke metal corrosion, ndị mmadụ chepụtara mgbochi nchara.Ụkpụrụ ya na-emegide nchara na-agụnyekarị ụkpụrụ mgbochi na ụkpụrụ nchebe cathodic.

Nke mbụ, otu n'ime ụkpụrụ ndị na-emegide nchara nke agba agba agba bụ ụkpụrụ mgbochi.Agba mgbochi nchara nwere ihe ndị nwere ike ịmepụta ihe nkiri nchebe.Ihe nkiri nchebe a nwere ike ikpuchi elu igwe, na-egbochi ikuku na ikuku mmiri ma gbochie ha imebi ígwè.Igwe ihe nkiri a na-echebe ihe nkiri na-ekere òkè n'ichepụta ígwè ahụ site na gburugburu ebe obibi, si otú ahụ gbasaa ndụ ọrụ nke ngwaahịa ígwè.

Ụkpụrụ mgbochi ọzọ nke nchara bụ ụkpụrụ nke nchebe cathodic.Agba mgbochi na-enwekarị ion metal ụfọdụ.Ions ígwè ndị a nwere ike ịmepụta ihe mgbochi electrochemical na-echebe n'elu ígwè ahụ, na-atụgharị ígwè ahụ ka ọ bụrụ anode, si otú ahụ na-ebelata mmeghachi omume oxidation n'elu igwe ma na-ebelata ọnụ ọgụgụ corrosion nke ígwè ahụ.Nke a na-egbochi nchara nwere ike ịmepụta nchebe cathodic dị ka zinc, aluminom na ọla ndị ọzọ, si otú ahụ nweta mgbochi nchara nke ọma.

N'ozuzu, ụkpụrụ mgbochi nchara nke agba agba agba na-egbu oge na-egbu oge nke corrosion metal site na mgbochi na nchebe cathodic, ma na-echebe àgwà na ndụ ọrụ nke ngwaahịa ígwè.Ya mere, na ngwa injinia n'ezie, ọ dị ezigbo mkpa ịhọrọ agba mgbochi nchara kwesịrị ekwesị, nke nwere ike ịbawanye ndụ nke ngwaahịa ígwè ma belata ụgwọ ọrụ.
