Corrosive Effect

Abstract The electrode potential behavior of aluminum investigated in buffer solutions of pH 4-8 containing varying concentrations of chloride ions, shows that the electrode potential does not respond to variations of pH. It changes linearly with pCl yielding a more or less constant Eo′ value of —0.54 volt. The corroding effect of the chloride ions supposedly is restricted to the adsorption of these ions on the surface and the electrode behaves as one of the second type. The oscillograms obtained both with the pure metal and with its alloys indicate that the surface oxide resists the corrosive effect up to a 0.1-N [CI–]. At higher concentrations, the electrode surface is appreciably activated acquiring relatively high double layer capacities, prominent passivity being achieved only on passing appropriate amounts of electricity. 6.4.2

Adsorbed Sulfur

The influence of the H2S concentration on the charge required for oxidation of the adsorbed sulfur and on the nonstationary currents passing through the electrode was studied while hydrogen sulfide was introduced into the solution. At higher concentrations, more sulfur atoms are adsorbed on one platinum surface atom. Upon decreasing the concentration one atom of sulfur per one surface atom results and the number of sulfur atoms blocking two surface atoms starts growing gradually.

When sharp metal filaments of W, Fe, Nb or Ta are observed in the field-ion microscope (FIM), their appearance is differentiated primarily by variations in regional brightness. This regional brightness, particularly prominent at liquid nitrogen temperature has been attributed in the main to chemical specificity which manifests itself in a paricular array of surface-atom electron-orbital configurations.Recently, anomalous image brightness and streaks in both fcc and bee materials observed in the FIM have been shown to be the result of surface asperities and related topographic features which arise by the unsystematic etching of the emission-tip end forms.
