Item Description

The present specification deals with the description of a training device for the introduction to the Cathodic Protection discipline.

The specification limits its view over the functions of the training bench, giving the primary list of experiments with which the student can try by himself to practically deepen into the phenomena of the corrosion control of metals in contact with the electrolyte. The theoretical study that precedes the experiments is reported in the manual, essential part of the bench. In this book the background and the scope of the experiment are easily explained.

The bench provides facilities to study the case of isolated systems, as well as the case of systems where different metals are coupled together. Particular attention is given to the presence or not of several kinds of insulating materials over the surfaces of the samples, in order to demonstrate the different behavior of the same material when coated or bare.

The bench provides suitable devices to highlight the concept of the free corrosion potential, measured with easy to use reference electrodes and means suitable to build with a certain accuracy the polarization curves.

Protective techniques are represented as per sacrificial anodes systems of several type of metals as per impressed current Cathodic Protection systems, with the possibility to see which is the
explanation of the use of constant voltage, constant current and constant potential feeders.

The bench is provided with measuring facilities characterized by suitable sensitivity and accuracy.

A suitable multi‐channel interface can connect the bench to a PC in order to record the experiment results and give the trace for further studies.
