Abstract: (273 Views)
The inhibition behavior of 1H-benzotriazole on corrosion of mild steel and Aluminum alloy 1050 in single and couple modes was investigated in sea water by immersion, Tafel polarization and electrochemical impedance spectrometry methods. The results indicated that an increase in inhibitor concentration cause to enhance in inhibition efficiency for both MS and AA1050 in single mode. In this case, the use of 0.01 M BTA caused to 50 and 70 percent reduction in corrosion rate of mild steel and AA 1050, respectively. BTA adsorbed on both MS and AA1050 surfaces physically according to the Langmuir adsorption isotherm. BTA was adsorbed on mild steel surface chemically when mild steel coupled to AA1050 which in turn caused the corrosion rate of mild steel to reduce more than 95 percent with respect to reference sample.
