摘要 |
The invention provides an electrochemical noise method, apparatus and system for estimating parameters of interest related to corrosion rates of an electrically conductive article, the method comprising: placing a working electrode, a reference electrode, and a counter electrode in an environment of interest; measuring potential at open circuit between the working electrode and the reference electrode over time; placing the working electrode under potentiostatic control; measuring current between the working electrode and the counter electrode for a predetermined period of time, the period of time of measurements may be extended to include a transient event; and estimating the corrosion rate. |
