1. A method for measuring localized corrosion and other heterogeneous electrochemical processes comprising the steps of:

  • forming an integrated multi-sensor wire beam electrode system whose working surface simulates a conventional one piece metal electrode surface in electrochemical behavior;

    exposing the working surface of the wire beam electrode to an electrolyte as a conventional one-piece electrode surface to allow localized corrosion or other heterogeneous electrochemical processes to occur;

    measuring local electrochemical parameters from local areas of the wire beam electrode surface by means of wires located at these local areas using read-out means;

    calculating local electrochemical kinetics of localized corrosion and other heterogeneous processes by means of kinetic equations derived based on the wire beam electrode concept.
