“…Since the pioneering work of Organ [1] on corrosion structure developed on archaeological bronze artifacts, numerous advancements have been made to understand patina growth in several areas around the world [2][3][4][5][6][7][8][9][10][11]. These investigations revealed many similarities, such as a high tin content within the corrosion layer, and a mostly isomorphic alteration preserving the original morphology of the ancient artifacts.…”

This paper establishes a comparison between the interface exhibited by an archaeological bronze alloy when previously submitted to a burial environment and a chloride electrolyte. The SEM-EDAX analysis shows that the archaeological surface exhibited a three layered structure characterized by a tin enrichment at the inner layer, the succeeding layer being only by copper species, the outer layer is relevant of the burial environment. This corrosion structure is to be regarded as Type I morphology described in the literature for bronzes exhumed in the northern side of the Mediterranean Sea. When submitted to chloride solution, the open circuit potential of material tends to constant values after five days of immersion time. The evolution of the resulting interface was characterized using EIS and the spectra obtained were tentatively fitted using a simple electrical equivalent circuit. When, the interface attained the steady state, the interface shows a patina with two layered morphology similar to the archaeological one.

“…It is generally accepted that in the corrosion of bronze, the alloy behaves similarly to metallic copper. 8 This model is, however, insufficient to describe reality, as most of the time other alloying elements are present in the cast alloys and will also influence the corrosion.…”

Micro-Raman spectroscopic analysis of different species of copper sulfates was carried out. Products such as antlerite, brochantite, posnjakite, langite and chalcanthite were investigated. These products are most likely to be formed as the result of atmospheric corrosion of copper alloys, e.g. bronze in sulfur-bearing environments. A database containing the characteristic Raman spectra was set up. This database was then used to investigate some specimens of copper alloy artefacts, that had been exposed to the atmosphere. It was shown to be possible to identify the nature of the corrosion products formed, using micro-Raman spectroscopy.
