Electrochemical corrosion test device and method for electrochemical corrosion testing

摘要

A corrosion test apparatus 100 configured to detect a corrosion property of a sample 1 by an electrochemical measurement includes an electrode holder 10 configured to receive and electrically contact the sample 1 so that the sample 1 forms a main electrode 11 for electrochemical measurement and a sample surface 2 of the sample 1 received by the electrode holder 10 is exposed, the electrode holder 10 having an electrochemical measurement counter electrode 12 positioned at a distance from the sample surface 2 of the sample 1 held by the electrode holder 10, and the electrode holder 10 is configured for releasably receiving the sample 1 and the counter electrode 12 and the sample 1 with the electrode holder 10 relative to each other are positioned so that when a temperature change of the sample 1 below the dew point on the sample surface 2 a Betauungs Nied impact is formed, which forms an electrolyte compound 3 between the counter electrode 12 and the sample 1. A method for investigating the corrosion of a sample with the corrosion test apparatus 100 will also be described.
