Benzotriazole (BTA) and tolyltriazole (TTA) were used to passivate pure copper chromium bronze alloys for environmental protection. Using the chemical immersion treatment, a dense film of chromium-free passivation layer was formed on surfaces both alloys. Microstructure, crystalline phases bonds layers systematically characterized, mechanisms studied. The mainly consisted CuO, Cu2O, polymers Cu...
