چکیده
|
The purpose of this paper is to evaluate the electrochemical kinetics parameters of galvanic corrosion inhibition of the copper alloy- steel alloy couple,exposed to cooling tower water. polyvinyl alcohol was utilized to evaluate the inhibition behaviour under galvanic couple conditions. polarization technique was used to evaluate the corrosion rate data. barnartt's three point method and mclaughlin method were used to evaluate the kinetics parameters. the results were compared with the results of conventional tafel extrapolation method.
