A mechanistic-based understanding of corrosion is needed in order to predict aging characteristics and reliability of either electronic or structural components. Although it is well known that the presence of a halide such as Cl− is necessary for p

Secondary ion mass spectrometry (SIMS) has been used in conjunction with isotopic labeling to determine the extent and rate of passive film hydration on aluminum. The rates at which oxygen- and hydrogen-containing species migrate through the film hav

High purity Al samples were implanted with 35 keV Cl+ then polarized in Cl--free electrolyte in order to ascertain corrosion behavior as a function of Cl content. Electrochemical data indicated implant fluences between 5x1015 and 2x1016 Cl+cm-2 resul

The pitting potential of pure aluminum thin films in 50 mM K 2 SO 4 was measured as a function of implanted Cl fluence. Samples were implanted with 35 keV Cl + at room temperature using fluences from 2.25 X 10 16 to 3.25 X 10 16 ions cm -2 in increme

Insight into the influence of Cl on the pitting behavior of aluminum has been gained using a combination of ion implantation and oxide deposition. High-purity Al thin-film samples were implanted with 35 keV Cl + followed by plasma deposition of an al
