Description

technical field [0001] The invention relates to an automatic dry-wet cycle device for corrosion test samples. Background technique [0002] Atmospheric corrosion tests often need to study the influence of dry and wet state changes on the metal corrosion process caused by day and night, wind, frost, rain and snow weather changes. In the laboratory, a dry-wet cycle device is usually used to continuously change the state of the corrosion sample to simulate the natural environment. Wet and dry cycle changes for corrosion testing. At present, the manual method is usually used to lift the sample in the solution or the liquid level of the solution to realize the dry-wet cycle. Since the corrosion test usually needs to be cycled once or several times a day, and it is carried out continuously for more than dozens of days, this manual operation is a waste of manpower. The efficiency is low, and it cannot meet the requirements of long-term accurate automatic measurement. Contents of...
