1. Ihe gbasara gburugburu ebe obibi nke corrosion
Latitude na longitude, okpomọkụ, iru mmiri, ngụkọta radieshon (uv ike, oge anwụ anwụ), mmiri ozuzo, pH uru, ifufe ọsọ, ifufe direction, corrosive sediment (C1, SO2).
2. Mmetụta nke ìhè anyanwụ
Ìhè anyanwụ bụ ebili mmiri electromagnetic, dị ka ike na ugboro nke ọkwa na-ekewa n'ime ụzarị gamma, X-ray, ultraviolet, ìhè a na-ahụ anya, infrared, microwave na ebili mmiri redio.Ihe ngosi ULTRAVIOLET (UV) bụ nke radieshon dị elu, nke na-emebi emebi karịa ụdị ike dị ala.Dịka ọmụmaatụ, anyị maara na ọ bụ ụzarị ultraviolet nke anyanwụ na-akpata ntụpọ gbara ọchịchịrị na akpụkpọ ahụ na ọrịa kansa.UV nwekwara ike imebi njikọ kemịkalụ nke ihe, na-eme ka ọ gbajie, dabere na ogologo ogologo nke UV na ike nke njikọ kemịkal nke ihe ahụ.X-ray na-enwe mmetụta na-abanye n'ime ya, ụzarị gamma nwekwara ike imebi njikọ nke kemịkalụ wee mepụta ion chaja n'efu, nke na-egbu ihe ndị dị ndụ.
3. Mmetụta nke okpomọkụ na iru mmiri
Maka mkpuchi ọla, oke okpomọkụ na iru mmiri na-enye aka na mmeghachi omume oxidation (corrosion).Ọdịdị molekụla nke agba n'elu osisi mkpuchi agba dị mfe imebi mgbe ọ nọ na ọnọdụ okpomọkụ dị elu ruo ogologo oge.Mgbe iru mmiri dị elu, elu ahụ na-adị mfe ikpokọta ma na-eme ka ọnọdụ corrosion electrochemical dịkwuo elu.
4. Mmetụta nke ph na arụ ọrụ corrosion
Na nkwụnye ego ọla (zinc ma ọ bụ aluminom) ha niile bụ ọla amphoteric na acid siri ike na ntọala nwere ike mebie ha.Ma dị iche iche metal acid na alkali iguzogide ike nwere àgwà nke ya, galvanized efere alkaline eguzogide bụ ubé ike, aluminum zinc acid iguzogide bụ ubé ike.
5. Mmetụta nke mmiri ozuzo
Nguzogide corrosion nke mmiri ozuzo na osisi a na-ese ihe na-adabere na nhazi nke ụlọ na acidity nke mmiri ozuzo.Maka ụlọ ndị nwere nnukwu mkpọda (dị ka mgbidi), mmiri ozuzo nwere ọrụ na-ehicha onwe ya iji gbochie mmebi ọzọ, ma ọ bụrụ na a na-eji obere mkpọda kpụzie akụkụ ahụ (dị ka ụlọ elu), mmiri ozuzo ga-edebe n'elu maka a. ogologo oge, na-akwalite mkpuchi hydrolysis na mmiri penetration.Maka nkwonkwo ma ọ bụ mbelata nke efere ígwè, ọnụnọ nke mmiri na-eme ka ohere nke electrochemical corrosion dịkwuo elu, ntụgharị uche dịkwa oke mkpa, na mmiri ozuzo acid dị njọ karị.
