Öğe Corrosion inhibition of brass in presence of terdentate ligands in chloride solution(Pergamon-Elsevier Science Ltd, 2005) Asan, Abdurrahman; Kabasakaloğlu, M.; Işıklan, Muhammet; Kılıç, ZeynelThe inhibition of two terdentate ligands, 2-[(E)-pyridin-2-ylimino)methyl)]phenol and 2-[(pyridin-2-ylamino)methyl]phenol, abbreviated L, and L, respectively, on the corrosion of brass in 0.10 M NaCl solution under various conditions, has been studied by means of the potentiostatic polarization and AC impedance methods. The studies show that terdentate ligands, L-1 and L-2 inhibit the corrosion of brass in chloride solution and that the inhibiting efficiency increases with an increase in their concentrations. Self-assembled films of these substances were also prepared on the brass surface. These films improved significantly the protecting ability of brass surface to corrosion in 0.10 M NaCl solution. When the films were modified with benzotriazole (BTA), the quality and corrosion resistance of films improved markedly. (c) 2004 Elsevier Ltd. All rights reserved.
