Setup and selection of cleaning methodologies In the case of metallic artefacts, corrosion rate can be measured by means of in situ electrochemical techniques. It is therefore possible to evaluate, for example, the effect that cleaning has on degradation rate. It is important to check that all the undesired or […]

Measurement and monitoring of degradation rate by means of non-destructive and in situ methodologies Measurement and monitoring by means of non-invasive or micro-destructive technologies is an important research topic for the MaMeCH laboratory. In particular, galvanic sensor have been set up for the continuous monitoring of gilded bronzes. In addition, […]
Protective coatings and corrosion inhibitors Benzotriazole (BTA) despite its toxicity is still the most frequently used corrosion inhibitor by restorers. Also in terms of protective coatings, an optimal product has not yet been identified because it is hard to combine on a single product different requirements such as: good protection, […]
Monitoring and conservation of Ghiberti’s Porta del Paradiso TThe project was initially related to the selection of the optimal solution for the exposition to the public of the Porta del Paradiso. Thank you to the use of galvanic sensors, which simulate the actual artefact in terms of composition and stratigraphy, […]
Atmospheric corrosion of copper alloys The project, coordinated by the KTH of Stockholm (Prof. I. Odnevall Wallinder) and funded by the European Copper Institute, is aimed at the study of the degradation processes of copper based alloys exposed outdoor and involves the exposition of samples in several European sites. Particular […]
