A na-akpọ ọnọdụ elu nke ọkpọkọ ígwè dị ka gburugburu ebe obibi na nke a bụ site na mkpuchi ọkpọkọ ígwè na ihe mkpuchi ala gbara ya gburugburu, ọnọdụ ọkpọkọ dị iche na izu anọ nke ala.Ya mere oyi akwa mgbochi corrosion ọkpọkọ bụ ihe mgbochi dị mkpa iji gbochie mbuze ala.Otu ọkà mmụta si mba ọzọ a ma ama tinye n'ihu "3PE oyi akwa nchekwa France", ka ọ dị ugbu a, a na-eji ụzọ mgbochi corrosion eme ihe n'ọtụtụ ebe.

Ọrụ ndị bụ isi nke mkpuchi erw pipe:

1, na-eme ka elu nkeERW ígwè ọkpọkọ free si electrochemical corrosion nke ala ala, bụ isi physics nke nje corrosion nchebe.

2, iguzogide mmegharị nke ala ọkara mgbakasị ahụ, nrụgide kwụ ọtọ na usoro ike abrasion na nhazi nke nchekwa igwe bụ isi.
