In this study the corrosion behaviour of bronze has been compared to that of both the pure alloying elements and the metallic materials approximately reproducing the composition of the dendritic and interdendritic phases. The results show that bronze is affected by the galvanic corrosion of copper-rich dendritic regions, stimulated by the nobler tin-rich interdendritic phase. When 3-mercaptopropyl-trimetoxy silane (PropS-SH) is applied on bronze the practical nobility of the interdendritic zones re-mains higher than that of the dendrite cores, but the galvanic activity of both regions is greatly reduced.

Abstract

In this study the corrosion behaviour of bronze has been compared to that of both the pure alloying elements and the metallic materials approximately reproducing the composition of the dendritic and interdendritic phases. The results show that bronze is affected by the galvanic corrosion of copper-rich dendritic regions, stimulated by the nobler tin-rich interdendritic phase. When 3-mercaptopropyl-trimetoxy silane (PropS-SH) is applied on bronze the practical nobility of the interdendritic zones re-mains higher than that of the dendrite cores, but the galvanic activity of both regions is greatly reduced.
