Electrochemical Study of a Hydrophobic Film of γ-Al₂O₃/Hdtms on Low Carbon Steel

The corrosion phenomenon affects several low carbon steel structures leading to excessive expenditure on coatings and other alternatives. However, the used usually contain compounds that pollute environment. Therefore, environmentally friendly, economical transparent or films have been developed. sol-gel method is a reliable way for development of anticorrosive films, as case alumina silica films. In this work, protective capacity an alumina/HDTMS film was studied. sintered at 350, 450 550 °C then 1% HDTMS deposited. ability γ-Al 2 O 3 /HDTMS evaluated by Electrochemical Impedance Spectroscopy (EIS) Potenciodynamic Polarization Curves (PDP). electrochemical results showed Al provided better protection compared metallic substrate. contact angle degree measured determined hydrophobic superhydrophobic properties.
