Photo-induced passivation: A new corrosion mitigation strategy for bronze artefacts
Source abstract
Abstract
The corrosion behaviors of four ternary Cu-Sn-Pb alloys with varying tin contents were investigated to determine the impact of tin content on the photo-induced corrosion of bronze. Photo-induced passivation, which effectively inhibits corrosion, was observed in all the investigated Cu-Sn-Pb alloys, even those with relatively low tin content, and a possible mechanism was proposed. Based on these findings, photo-induced passivation treatment was applied to two types of artificially patinated bronzes, achieving inhibition efficiencies of up to 82 % and 93 %. This method offers a novel corrosion mitigation strategy for bronze artifacts, capable of avoiding contamination of archaeological artifacts by foreign substances.
