Abstract: The inhibitive property of (heptadecafluoro-1, 1, 2, 2-tetrahydrodecyl) trimethoxysilane on 304 stainless steel has been investigated by electrochemical measurements.Resultsshowed that the presence of (heptadecafluoro-1, 1, 2, 2-tetrahydrodecyl) trimethoxysilane decreased the self-corrosion current density, increased the charge transfer resistance and pitting corrosion potential of 304 stainless steel, and that the corrosion inhibition efficiency was up to 96%.
