Under the combined action of organic acid atmosphere and SO2 pollutant, the copper matrix exhibits complex corrosion behavior. The corrosion products are agglomerated with each other and even connected with each other in acetic acid atmosphere to form a sheet structure and constitute a new rust layer. In electrochemical tests, it was found that compared with the same concentration of organic acid atmosphere, the material showed a more serious corrosion tendency after adding Na2SO4. The self-corrosion current density is much higher than that of the experimental group without adding Na2SO4, and the charge transfer resistance is also much lower than that of the experimental group without adding Na2SO4. The concentration of organic acids in the atmosphere and the concentration of pollutants in the solution are also important influencing factors. With the increase of the concentration of the two, the material matrix will suffer more serious corrosion damage. In addition, because of its strong acidity, formic acid is easier to ionize H+ in the corrosive medium, thus showing a stronger corrosion ability than acetic acid under the same conditions. TP2 copper workpieces will inevitably encounter the erosion of harmful gases such as organic acids and SO2 in the industrial environment. How to effectively isolate or reduce the impact of these corrosion factors on the material and improve the service life of the material is a direction worth continuing research.
