Feasibility Study of Natural Honey Use as Corrosion Inhibitor in Protecting the Bronze Artifacts (original) (raw)

Bronze disease is the most important phenomenon giving rise to the destruction of the bronze objects. There are various methods for preventing and slackening the disease. In this regard The use of corrosion inhibitors in the field of historical metal protection has been widely considered. But, the most important method which is also the best method offered for such a purpose is the use of benzotriazol (BTA) and 2-amino-5-mercapto1,3,4-thiadiazol (AMT) inhibitors. Under ideal circumstances, these inhibitors deliver good inhibition and can control the disease. The most important problem posed by such inhibitors is their being toxic and carcinogenic. In the current research paper, the natural inhibitors residing Honey in concentrations ranging from 1600ppm to 2000 ppm in sodium chloride corrosive solution, 0.5M, were applied on a bronze alloy in a percentage similar to the archeological alloys, 10% Wt Sn, Cu-10Sn composition. The effects were evaluated by the use of Potentiostat device...
