Abstract	The atmospheric corrosion behavior of benzotriazole treated Cu-based coins in synthetic sweat was investigated. Electrochemical impedance spectroscopy showed that the protective effect of BTA on copper coins gradually failed in synthetic sweat with the prolongation of immersion time. The copper coin coated with BTA protective film had a faster corrosion rate under cyclic wet-dry test of regularly wetting synthetic sweat. From the composition analysis of protective film and corrosion products, BTA not only complexed with Cu2+ Cu2+, but also reacted with Zn2+/Ni2+. The thickness of the patina layer can reach to 100 mu m after 240h accelerated experiment, and the corrosion products were simple in composition, mainly basic Cu-2(OH)(3)Cl and oxides of Ni and Zn. However, BTA had little protective effect on copper in synthetic sweat, and didn't affect the composition of final corrosion products.
