Abstract(s)
The corrosion of brass in deoxygenated nonbuffered
and buffered artificial and natural seawater was
studied. The weight gains and the average corrosion rates
of brass samples, immersed in both media during periods of
1 week, 1 and 3 months, were determined.
The morphology of the corroded surfaces, with and
without the corrosion products, was analyzed by visual
observation and scanning electron microscopy (SEM).
Energy dispersive spectroscopy (EDS) was used for the
identification of the corrosion products and X-ray diffraction
(XRD) for the identification of the crystalline
corrosion products.
In general it was concluded that deoxygenating and
buffering, at pH 9, both contribute to enhance the corrosion
of brass in seawater
