Abstract

A new experimental electrochemical system was developed for measuring corrosion rates in high temperature dilute electrolyte solutions. The system was tested at temperatures and pressures up to 350 °C and 20 MPa. The low corrosion rates in the aqueous boiler solutions are difficult to quantify using the traditional mass loss and metallography techniques. The newly designed electrochemical system with annular-duct flow-through workingcounter electrode assembly was proved to be efficient for in-situ corrosion studies. The electrochemical impedance spectroscopy (E1S) methods were found the most applicable techniques to measure the corrosion current in the high temperature/very dilute electrolyte solutions at temperatures to 350 °C.
