Abstract

Deterioration phenomena occurring on outdoor-exposed cultural heritage have been the subject of several studies, but relatively few works have investigated the specific role of Particulate Matter (PM) in the corrosion of metallic artefacts. To face the latter aspect, a device called “Deposition Box” was recently designed and validated to get rid of variables such as wind and rain in collecting ambient PM on different materials. In any case, beside necessary field exposures, accelerated ageing tests are also required to isolate and better understand deterioration mechanisms due to specific variables. For this reason, preliminary tests have been performed to set-up a methodology to reproduce and analyze the effect of PM on quaternary bronze (G85) specimens through accelerated ageing in climatic chamber.
