Atmospheric CORRosion and mechAnical alteration of bronze BELLs: a sound and artistic heritage in danger ? – BellACorr
The bronze bell (22% wt Sn - a / d phases) is a musical and communication instrument, but also by its ornamental epigraphy, a work of art. It is a historical and cultural heritage to be preserved. From its implementation, the bell is subjected to a physicochemical alteration due to an aggressive environment, and mechanical to ring it. Proposing a micro-infiltrating mechanism of its alteration and quantifying the impact on its sound qualities is a major issue for the bell conservation.
