Problems solved by technology

[0003] The atmospheric corrosion sensor involved in the invention patent CN201710628969.7, the invention patent CN201711322517.2, and the invention patent specification CN201210520336.1 has the following problems: the sensitivity in the atmosphere is poor due to the large distance between the positive and negative electrodes, especially in the relative In case of low humidity, the sensor can only be used in solution or when it rains
There is still a problem in the invention patent CN201710628969.7 and the invention patent CN201711322517.2: the cathode material and the anode material are corroded and cross-contaminated in the atmosphere. If the sensor is used for a long time, it needs maintenance, otherwise it will cause data distortion
[0004] Atmospheric corrosion sensors with high sensitivity and long life are still lacking

Abstract

The invention discloses an atmospheric corrosion sensor. The atmospheric corrosion sensor comprises an anode material layer, a cathode material layer and an insulating material layer between the anodematerial layer and the cathode material layer. The anode material layer and the cathode material layer are respectively configured to connect with a wire or a probe in order to connect with the atmospheric corrosion sensor with an external current detection device. The anode material layer, the cathode material layer and the insulating material layer are configured to be completely consistent with one another and can be closely packed together in a sheet-like shape. The invention further discloses a method for manufacturing the atmospheric corrosion sensor. The method comprises a step of tightly laminating an anode material layer, an insulating material layer and a cathode material layer, and a step of constructing the anode material layer, the insulating material layer and the cathode material layer in the same shape and having grooves and / or holes aligned with each other.

Description

technical field [0001] The invention belongs to the field of atmospheric corrosion monitoring, and in particular relates to an atmospheric corrosion sensor and a manufacturing method thereof. Background technique [0002] According to relevant domestic and foreign standards, the evaluation of atmospheric corrosion mainly relies on one-year exposure corrosion test or one-year environmental corrosion factor monitoring for corrosion classification, which is time-consuming and laborious, and continuous corrosion data cannot be obtained, and the corrosion process cannot be characterized . Since the corrosion of metals in the atmosphere is mainly electrochemical corrosion, the atmospheric corrosion sensor relies on the corrosion current generated in the atmosphere by the potential difference between the two cathode and anode materials to achieve continuous detection of atmospheric corrosion, which can well solve the above problems. [0003] The atmospheric corrosion sensor involv...
