摘要: Abstract The effect of leaching rain on the corrosion behaviour bronze UNSC83600 was investigated as to influence alloying elements (Cu, Sn, Zn, Pb) through dropping tests simulating a severe runoff condition with solution reproducing natural acid rain. Corrosion followed time monitoring both samples and solutions (up 30 days) by SEM, EDS, Raman spectroscopy, XRD, AAS. patina behaves porous layer enriched in stable tin compounds allowing uniform dissolution Cu, Zn partly Pb. Laboratory results are good agreement field studies outdoor bronzes unsheltered condition.
