Development of a novel measuring methodology, based on local impedance measurements, for the study and the prevention of the local corrosion of copper

    Project Details

    Description

    Local corrosion of metals is a very fast process which is difficult to detect, and therefore it has to be avoided. Also copper can in some cases be locally attacked, e.g. by pitting corrosion. In order to be able to protect metals against local corrosion, the mechanism of the underlying reactions need to be known.The aim of this project is to develop a methodology to investigate local corrosion processes. After that, a method to protect copper against local corrosion will be searched for. Recently, a new technique based on electrochemical impedance spectroscopy (EIS) has been developed to study local electrochemical reactions. It is called LEIS (Local Electrochemical Impedance Spectroscopy). The introduction of this technique in corrosion system would mean a break-through in this field. Making use of LEIS, a model will be formulated for the reactions taking place on a locally corroding Cu surface. Afterwards, a method for corrosion protection will be developed, modeled and optimized.
