The corrosion rate of SAE 5115 steel located inside a garbage compactor trucks and the corrosion products originated by an aqueous solution called leachates containing dissolved salts and heavy metals at room temperature and for exposure of five years were studied.We conducted accelerated trials using a contaminant such as the above-mentioned slurry.Microscopy techniques and polarization curves were used.Using microscopic techniques, the degree of advance was determined and correlated with the corrosion rate, determining the degree of deterioration due to pitting type corrosion, establishing a direct relationship between the rate of deterioration and the time of onset of pitting corrosion in contact with leachates.
