THE ACCELERATED CORROSION BEHAVIOUR IN SALINE ENVIRONMENTS OF SOME SAMPLES MADE OF TOMBAC, COPPER AND ALUMINIUM

The corrosion tests from this paper simulate the exposure conditions in different environments of some samples made from yellow tombac, copper and aluminium. For the tombac samples a salt fog chamber was used, the copper and aluminium samples a 3% NaCl solution was prepared and the exposure time being 144 h at 35 oC temperature. The samples surface morphology before and after the corrosion tests were analyzed by means of the scanning electron microscope (SEM). Also, the crystalline structure of the metallic samples was assayed with the X-ray diffractometer (XRD).
