Surface characterization of a corroded bronze-leaded alloy in a salt spray cabinet
The corrosion products of a TM 23 bronze-leaded alloy (Cu 72%, Pb 15%, Zn 8% and Sn 5%) were obtained in a salt spray cabinet after exposition during 120 h and 1000 h. The products obtained were studied using scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. The major products of bronze-leaded corrosion were oxides and basic salts of Cu, CuCl2 center dot 3Cu(OH)(2), and Pb, Pb(OH)Cl. The results can be attributed to a kinetic control of the corrosion reactions. (c) 2007 Elsevier B.V. All rights reserved.
