Self-assembled monolayers of 1 H, 1 H, 2 H, 2 H-Perfluorodecyltriethoxysilane ( PFDS ) were formed on the 430 stainless steel surface. The analysis of Fourier transform infrared ( FTIR) spectroscopy, contact angle, polarization curves and electrochemical impendence spectrum, and corrosion morphology in ferric chloride solution were used to study the adsorption of PFDS SAM and its corrosion inhibition performance for 430 stainless steel . The results showed that PFDS SAM exhibited better corrosion resistance at 2 h self-assembling time point, and the PFDS SAM formed at the curing temperature of 150 ℃ for 1 h has more excellent corrosion inhibition performance.
