Dịka ọkọlọtọ siri dị, ngwa igwe eji eme ihe na kichin ga-enwerịrị ọgwụgwọ mgbochi corrosion. Ihe mkpuchi elu ma ọ bụ ihe mkpuchi kwesịrị inwe ike iguzogide ule nnu nnu acetic acid nke awa 24 (ASS). A na-ekewa ikike mgbochi corrosion nke ngwaahịa ahụ n'ime akara ule dị iche iche: ngwaahịa dị mma (ọkwa A) ga-enwetarịrị ọkwa 10, ngwaahịa B ga-enwetarịrị ọkwa 8, yana ngwaahịa Grade C ga-enweta ma ọ dịkarịa ala ọkwa 7.

Enwere ụdị nnwale ịgba nnu atọ: ịgba nnu nnu na-anọpụ iche (NSS), spray acetate (AA SS), na ọla kọpa accelerated acetate spray (CA SS). N'ime ha, ule ịgba mmiri na-anọpụ iche bụ nke a na-ejikarị eme ihe. Ọ na-agụnye ịgbasa ihe ngwọta sodium chloride 5% n'ime ụlọ ule na ogo Celsius 35 iji mee ka corrosion gbasawanye na gburugburu mmiri oké osimiri. A na-enyocha arụmọrụ corrosion dabere na uru pH, na-eji nnu na-anọpụ iche sitere na 6.5 ruo 7.2, yana nnu acid sitere na 3.1 ruo 3.3.
