Description
The corrosion behaviour of mild steel in maize
juice, acidified maize juire and acetic acid environments
was studied in this investigation. The observed
corrosion reaction of the steel's surface in these
environments seems to be predominantly that of
general corrosion. The acetic acid environment was
found to be the most corrosive. The maize juice was
the least aggressive environment and this might be
due in part to the firm formation that tends to
passivated the steels surface. The strength properties
(load-to-failure and time-to-fracture) decreased with
increase in exposure time in the three environments.
The hydrogen atoms prod1,1a:d during the corrosion
reaction could diffuse into the steel matrix to cause
hydrogen embrittlement of the steel.
