and step 3: taking out the plate-shaped sample after the set corrosion time is up, performing surface characteristic characterization on the corroded and non-corroded plate-shaped samples, obtaining the surface micro-morphology and roughness r of the sample before and after corrosion by using a laser confocal microscope or a scanning electron microscope, and obtaining the apparent contact angle theta of the sample before and after corrosion by using a contact angle measuring instrument;
and 4, step 4: carrying out a pool boiling experiment on a corroded plate-shaped sample and a non-corroded plate-shaped sample to obtain the surface heat exchange characteristics of the sample material before and after corrosion, and specifically comprising the following steps: boiling curve, critical heat flux density and corresponding surface temperature;

As shown in fig. 2 to 4, different microstructure arrays can change the roughness and wettability of the material surface, thereby affecting the heat transfer characteristics of the material surface. In addition, the capillary wick effect brought by the microstructure also has great influence on the formation of critical heat flow density in the boiling heat exchange process of the material surface. As mentioned above, in addition to the laser processing method, chemical etching and other methods can obtain a microstructure surface with smaller dimension and higher processing precision on the surface of the metal material. Besides the microstructure surface, a chemical method can be used for preparing a porous coating on the material surface, and the coating is densely distributed with nano-scale porous structures, so that the hydrophilicity of the material surface is greatly influenced. In addition, other surface modification methods such as nanofluids, chemical vapor deposition, and the like are used to improve the heat transfer characteristics of the material surface.
As shown in fig. 6-8, the microstructure of the metal surface modified plate sample after corrosion. In addition, a pool boiling experiment is carried out on the plate-shaped surface modified samples before and after corrosion on the basis of microstructure measurement, and heat transfer characteristics of different samples under a pool boiling working condition are tested, so that a comparison result of influence of an actual corrosion working condition on the surface boiling heat transfer characteristics of the surface modified plate-shaped material can be obtained.
Through specific practical experiments, after a plate-shaped sample subjected to surface modification is placed in a high-temperature high-pressure reaction kettle with the temperature of 310 ℃, the pressure of 10Mpa and the pH value of 8.5 for continuous corrosion for 300 days, the sample is taken out and surface appearance and surface characteristic representation are carried out, the surface appearance of the sample after corrosion is shown in figures 6-8, the original microstructure on the surface of the sample is corroded and changed into a multi-scale and multi-level microstructure, the surface contact angle of the microstructure is also changed, and part of the surface of the sample is changed from hydrophobic before corrosion to super-hydrophilic after corrosion, so that the surface heat exchange characteristic of the sample is greatly influenced.
By adopting the method, the influence result of long-time corrosion on the surface characteristics and the heat exchange characteristics of different materials in an actual application scene can be obtained, and the result is used as an important reference basis for material selection in the actual application scene.
The foregoing embodiments may be modified in many different ways by those skilled in the art without departing from the spirit and scope of the invention, which is defined by the appended claims and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
