Investigation of Corrosion Protection by Chemically Applied Patina on Artistic Bronzes

Abstract

Increase of pollution in recent years, requires monitoring of the corrosion behavior of artistic bronzes coated with syntetic patina, in urban atmosphere. This present work aims to investigate the corrosion rezistance of various artificial patina currently used in bronze sculpture. Electrochemical and microscopic methods were used to investigate the protective effect of several chemically produced patinas on artistic bronze.
