Corrosion Resistance of Modified Silane Films Formed on AZ31 Magnesium Alloys

摘要：

This present work investigated the corrosion behavior of AZ31 magnesium alloy substrates pre-treated with bis-triethoxysilylpropyl tetrasulfide silane modified with cerium nitrate. The corrosion behavior of the pre-treated substrates in 0.005M sodium chloride solutions was assessed by potentiodynamic polarization, open circuit potential and electrochemical impedance spectroscopy (EIS). The results showed that the silane pre-treatments improved the corrosion resistance of the AZ31 magnesium alloy substrates in the presence of chloride ions. Especially the addition of cerium nitrate played an important role in reducing the corrosion activity.
