My purpose is to have data in order to make an FEM modeling for predicting the corrosion rate on this cans, depending on the content type and on the characteristics and the internal features, e.g. top surface of the container.
Try to measure PR for pure Tin cans not exposed to electroplating or any coating then test another with food using fresh water as electrolyte. Then check the synergetic effect of food corrosion rate to the pure Tin. Hopefully it will work.
Carlos,
You should drill a hole on one end to introduce a counter and reference electrodes. After that you can proceed in the usual way.
Hello Carlos,
the measurement of PR for food-metal interfaces should work the same way as for other non-liquids, e.g. soil. See for example http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6110218 Figure 7, where a cylindrical shaped container is used.
Kind regards
David
While the use of LPR is relatively simple, as others have said, I don't understand how you are planning to use the data obtained in an FEM model. LPR estimates the average corrosion rate in free corrosion conditions, but the use of an FEM model implies that you are concerned with the spatial distribution of corrosion, which in turn implies that you are concerned with galvanic corrosion, and hence not free corrosion conditions. Perhaps you can explain?
