| Abstract | Carboxylic acids with different carbon chains have different corrosion behaviors on copper tubes. In this paper, corrosion behavior and corrosion mechanisms of copper tubes in formic acid (HCOOH) and acetic acid (CH3COOH) were analyzed by vapor corrosion tests, electrochemical tests, contact angle examination, optical microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. The corrosion process of copper tubes in the HCOOH environment is more complex than in the CH3COOH environment and HCOOH is easy to cause "ant nest" corrosion on copper tubes. The corrosion rate is faster and the surface of the copper tube is more easily corroded in the CH3COOH environment due to the formation of unstable and loose corrosion products, Cu(OH)(CH3COO)(2)center dot 2H(2)O. The results of the contact angle examination showed that the contact angles of HCOOH and CH3COOH on copper tube surface were 25 degrees and 9 degrees, respectively, which means that CH3COOH is more likely to be absorbed by the surface of the copper tube evenly. Differences in the wettability of these two carboxylic acids with copper tubes are the main reason for the different corrosion phenomena. The corrosion mechanisms of copper tubes in carboxylic acid are also discussed. |
