Problems solved by technology

[0004] To sum up, for electrochemical samples in the prior art, for irregular or small samples to be tested, it is often necessary to seal the non-corrosion surface by means of mosaic, etc., and the process is cumbersome.
When measuring the area of ​​the surface of the sample to be tested, the measurement error is relatively large for the irregular sample to be tested
In addition, the relative position of the electrode used in the corrosion process and the sample to be tested is not easy to fix, and the electrochemical corrosion experimental device needs to be improved.

Description

technical field [0001] The invention relates to the field of material corrosion performance detection, in particular to an electrochemical test sample and a preparation method thereof. Background technique [0002] Electrochemical testing plays an important role in the characterization of metal corrosion, and is characterized by strong scientificity, fast accuracy, high precision, and good operability. Compared with the traditional weight loss method and salt spray corrosion test, it is easier to quantitatively evaluate the corrosion rate and corrosion resistance of materials. However, due to the characteristics of the electrochemical test, the preparation of the sample is particularly critical. The acquisition of the effective test area of ​​the sample directly affects the repeatability and stability of the later corrosion current density and AC impedance data, that is, the surface of the sample must have a certain The exposed surface area of ​​the sample, the remaining su...
