Abstract
- Preparation of 3-mercaptopropyl)trimethoxylsilane (PropS-SH) film on brass surface and its corrosion resistance performance were investigated by surface energy analysis, Fourier transform infrared reflection (FT-IR) spectroscopy and electrochemical measurements. The results indicated that the generation of PropS-SH sialne film on brass was based on spontaneous reactions to produce Cu-S, Zn-S bond and Si-O-Si bonds. When the brass substrate was covered with the prepared PropS-SH silane film, the dezincification coefficient of brass decreased from 4.45 to 0.47. The PropS-SH silane film was able to minimize the dissolution of both Cu and Zn, improving the corrosion resistance of brass in natural seawater.
