Metal corrosion na-ezo aka na mbibi nke metal na-emepụta site chemical ma ọ bụ electrochemical edinam nke gbara gburugburu, na mgbe na njikọ na anụ ahụ, n'ibu ma ọ bụ ndu ihe, ya bụ, mbibi nke metal n'okpuru omume nke gburugburu ya.
Ụdị corrosion metal a na-ahụkarị nke ihe na-ekpo ọkụ efere bụ ndị a:
Nrụrụ n'ụdị n'elu elu niile ekpughere na ọkara, ma ọ bụ n'akụkụ ka ukwuu, mmebi nke corrosion nke macro edo ka a na-akpọ corrosion otu.
Crevice corrosion siri ike nrụrụaka corrosion na-eme n'ime oghere na akụkụ ndị kpuchiri ekpuchi nke elu igwe.
Kpọtụrụ corrosion Ụdị metal ma ọ bụ alloy dị iche iche nwere ike ịkpọtụrụ ibe ha, na-emikpu na ngwọta ngwọta electrolyte, enwere ugbu a n'etiti ha, ọnụ ọgụgụ corrosion nke ikike ígwè dị mma na-ebelata, ọnụ ọgụgụ corrosion nke ike metal na-adịghị mma na-abawanye.
Igwe nbibi na-emebi emebi bụ ụdị mmebi nke na-eme ka usoro mmebi ahụ dịkwuo ngwa n'ihi mmegharị nke dị n'etiti etiti na elu igwe.
Nhọrọ corrosion Ihe omume na ihe mmewere dị na alloy na-emebi emebi bụ nke a na-akpọ corrosion nhọrọ.
A na-akpọ ikpochapụ corrosion n'otu n'otu n'otu obere ntụpọ dị n'elu igwe nke ịdị omimi nke corrosion dị ukwuu na-akpọ pitting corrosion, ma ọ bụ corrosion pore, pitting corrosion.
Intergranular corrosion Intergranular corrosion bụ ụdị corrosion nke na-akacha mma na-emebi ókèala ọka na mpaghara dị nso n'ókè ọka nke ígwè ma ọ bụ alloy, ebe ọka n'onwe ya adịghị emebi emebi.
Mbibi Hydrogen Mbibi nke ọla na ngwọta electrolyte site na infiltration hydrogen nwere ike ime n'ihi corrosion, pickling, cathodic nchedo, ma ọ bụ electroplating.
Mgbaji corrosion nrụgide (SCC) na ike ọgwụgwụ corrosion bụ ihe mgbaji na-akpata site na njikọta nke corrosion na nrụgide tensile na ụfọdụ usoro ígwè-ọkara.
