The corrosion of mild steel in maize juice, acidified maize juice and acetic acid environments.

摘要

The corrosion behaviour of mild steel in maizeudjuice, acidified maize juire and acetic acid environmentsudwas studied in this investigation. The observedudcorrosion reaction of the steel's surface in theseudenvironments seems to be predominantly that ofudgeneral corrosion. The acetic acid environment wasudfound to be the most corrosive. The maize juice wasudthe least aggressive environment and this might beuddue in part to the firm formation that tends toudpassivated the steels surface. The strength propertiesud(load-to-failure and time-to-fracture) decreased withudincrease in exposure time in the three environments.udThe hydrogen atoms prod1,1a:d during the corrosionudreaction could diffuse into the steel matrix to causeudhydrogen embrittlement of the steel.
