Abstract

The invention relates to the field of atmospheric corrosion protection, in particular to a method using liquid drop self-bounce effect to improve an atmospheric corrosion protective property of a sample. Hydrophobic treatment is conducted on the surface of the metal sample to form a nanoscale surface, then condensation treatment is conducted on the nanoscale surface, thus liquid drops are formed on the nanoscale surface of the sample, the liquid drops self-bounces, thus the liquid drops are changed from a wetting state to a non-wetting state, and thus the atmospheric corrosion protective property of the sample surface is improved. According to the method using the liquid drop self-bounce effect to improve the atmospheric corrosion protective property of the sample, atmospheric corrosion protective theories are enriched, theoretical basis is also provided for the development of the corrosion protective technology based on the liquid drop self-bounce effect of a super-hydrophobic surface, and the method using the liquid drop self-bounce effect to improve the atmospheric corrosion protective property of the sample has potential application value in the field of atmospheric corrosion protection.

Description

Technical field

[0001] The invention relates to the field of atmospheric corrosion protection, in particular to a method for improving the atmospheric corrosion protection performance of samples by using the self-bouncing effect of liquid droplets. Background technique

[0002] Atmospheric corrosion is an important issue that threatens the safe service of metal facilities. According to statistics, 80% of metal components are used in the atmosphere, and the direct economic losses caused by atmospheric corrosion in countries around the world account for about 1.5%-3% of the GDP. To deal with atmospheric corrosion, the current general protection methods are mainly to improve the corrosion resistance of the material itself or to isolate the substrate from the corrosive medium, which are often some passive protection methods. In these cases, the corrosive media present on the metal surface can induce corrosion to a certain extent. Therefore, the development of new and efficient meta...
