Atmospheric corrosion of bell bronze in an urban environment

What is it about?

To protect and preserve the bronze bells, which represent an ancient and modern multicultural heritage, one needs to understand precisely how they have changed over time. A comparative study of the corrosion facies that developed on the internal and external profiles of a bell exposed to an urban atmosphere for 90 years was conducted. In addition, this corrosion was compared to that of a bell exposed to a marine atmosphere for an equivalent amount of time. An original D218O-labeled atmosphere re-corrosion protocol and mass nanospectrometry analysis were used to study the microinfiltration properties of the urban patina.
