Electrochemical corrosion test equipment and procedures for electrochemical corrosion testing

摘要

Corrosion test device (100) which is configured for the detection of a corrosion property of a sample (1) by electrochemical measurement, comprising: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) is free of the sample taken by the electrode holder (10), with:the electrode holder (10) has an electrode (12) for electrochemical measurement positioned at a distance from the sample surface (2) of the sample taken by the electrode holder (10), and-the electrode holder (10) is configured for soluble sampling (1), characterized by:The counter-electrode (12) and the sample (1) with the electrode holder (10) can be positioned relative to each other in such a way that, if the temperature changes, the sample (1) is formed under the dipping point on the test surface (2) a beta precipitation is formed, which forms an electrolyte connection (3) between the counter-electrode (12) and the sample (1); andA test chamber (20) in which the electrode holder (10) is arranged with the sample (1) in a gaseous, water-resistant test atmosphere and contains a temperature device (21) with which the temperature of the sample (1) and/or of the test chamber (20) is adjustable.
