Title: Wettability Gradients On Anodized Aluminum Effects Of Surface Chemical Reactions

Abstract: Wettability variation of aluminum electrode surfaces was determined using a Wilhemly-type apparatus, in which the pull force exerted by the electrolyte solution on the electrode was measured at each switching of the electrode potential, for a periodically reversed step potential. The data obtained for aluminum and amalgamated electrodes show that metal-liquid surface tension is sensitive to the applied potential mainly through its effect on the chemical composition of the interface. The gradient of wettability induced by chemical reactions generates a displacement of the meniscus during the periodic polarization pulses. Wettability of aluminum surfaces in contact with H2SO4 solutions depends on the acid concentration, in agreement with previous results for iron-sulfuric acid systems.
