Abstract

The corrosive aggressiveness for scrap iron made up by two
non-ferrous scrap from copper and aluminum was determined form the
evaluation of deposition rate from chloride ions, sulphur dioxide and setting
dust from atmosphere. Besides, the corrosion rate in steel carbon test tube,
copper and aluminum formed their mass differences when it was compared
with the samples before and after the environment studied. For this, three
expositions sites one out and two in the storehouse were chosen where the
contaminants attracting were placed, and electrochemical sensors for the
determination of humidity and the air temperature, as well as metallic
probes. It was confirmed that the scrap iron is placed in a zone of high
corrosive aggressiveness determined by the presence of an industrialmarine-
urban atmosphere according to values obtained from deposition rate
from chloride ions and sulphur dioxide. This fact facilitated to estimate
the loss of masses in metallic probes because they increase in function of
the expositions time. According to the results the steel scrap in carbon and
aluminum are the ones that could have more estimated losses for a year of
storage.
