在 430 不锈钢表面制备了 1 H,1 H,2 H,2 H-全氟癸基三乙氧基硅烷( PFDS) 自组装膜。 通过分析傅里叶变换红外光谱、接触角、极化曲线和交流阻抗谱、在三氯化铁溶液中的腐蚀形貌,研究了 PFDS 自组装膜的吸附及其对不锈钢电极的缓蚀作用。 结果表明:组装时间为 2 h 时,PFDS 膜表现出较好的抗腐蚀性, 150 ℃ 固化1 h 后,自组装膜具有更优异的抗腐蚀性能。

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.
