چکیده
|
The corrosion inhibition of copper-nickel alloy by benzotriazole (bta) in 1.5. m hcl has been investigated by weight loss and polarization techniques at different temperatures. maximum value of inhibitor efficiency was 99.8% for bta at 35. °c and 0.1. m inhibitor concentration,while the lower value was 86.8% at 55. °c and 0.02. m inhibitor concentration. the non-linear region of the polarization curve near the corrosion potential can be discussed depending on data of over potential as a function of current densities. these data can be analyzed by suggestion of a mathematical model to take into account the effect of mass transfer on activation process. © 2011.
