The problems like water quality deterioration and fluctuation occurred in Yellow River become more and more severe.Therefore
the complex solution containing HEDP
PBTCA and Zn2+with a certain concentration was developed and used as inhibitor for condenser tube material(316Land 317Lsteel)in deteriorated Yellow River water.The polarization curves show that
the corrosion currents of 316 Land 317L in the deteriorated water decreased obviously.The electrochemical impedance spectroscopy(EIS)test results imply that
two capacitive impedance arcs appeared in the EIS of 316 Land 317L
indicating there were two cathode reactions controlled by active process.Some of the morphologies of scaling products on surface of 316 Land 317Lchanged from flake film to spheroid and rod like.
