Abstract

 ARCHEOLOGISTS HAVE LONG BEEN TRYING TO PROTECT OF ANCIENT METAL OBJECTS (ARTIFACTS CORROSION CONTROL). METALLIC CULTURAL HERITAGE ARE COMMONLY TREATED WITH INHIBITORS AND THEN EXHIBITED OR CONSERVED IN MUSEUMS. NOWADAYS BENZOTRIAZOL (BTA) IS ALMOST COMMON CORROSION INHIBITOR FOR BRONZE ARTIFACTS. BUT MANY PROBLEMS ARE THERE IN USING IT FOR NON-PORTABLE OBJECTS.THE STUDY AIMS TO EVALUATE THE ABILITY OF NEW CORROSION INHIBITORS (BTA GEL) TO PROTECT ARCHAEOLOGICAL BRONZE FROM CORROSION. THIS INHIBITOR WAS TESTED ON BRONZE COUPONS. ELECTROCHEMICAL MEASUREMENTS WERE CARRIED OUT TO EVALUATE THE PERFORMANCES OF THE CORROSION INHIBITOR SOLUTIONS AGAINST AQUEOUS CORROSION, AS WELL AS THE BEHAVIOR OF PROTECTED BRONZE SAMPLES IN A CORROSIVE ELECTROLYTE. ARTIFICIAL AGING IN CLIMATIC CHAMBER PROVED THE GOOD PERFORMANCES OF THE TREATMENTS AGAINST ATMOSPHERIC CORROSION, AND THEN WE USED THIS GEL FOR TREATMENT OF THE HISTORICAL BRONZE SAMPLE AND THE EFFICACY OF THE CHANGES ON THE PATINA SAMPLES WAS ASSESSED. FOR THIS PURPOSE, THE DIGITAL LOOP AND SCANNING ELECTRON MICROSCOPY WERE USED. THE STUDY INDICATES THAT THE GEL IS EFFICIENT.
