In Situ Studies of Passive Film Chemistry using X-ray Absorption Spectroscopy
Davenport, Alison J.; Bardwell, Jennifer A.; Isaacs, Hugh S.; MacDougall, Barry; Frankel, Gerald S.; Schrott, Alex G. ( 1993 )The passive film on sputter-deposited thin film Fe and Fe-26Cr electrodes has been examined using in situ X-ray Absorption Near Edge Spectroscopy (XANES). During the x-ray spectroscopic measurements, samples were maintained ... -
Electrochemical Quartz Crystal Microbalance Study of Corrosion of Phases in AA2024
Baek, Y.; Frankel, G. S. ( 2003 )The electrochemical quartz crystal microbalance (EQCM) was used to directly measure the dissolution rate at cathodic potentials, and thus the cathodic corrosion rate, of thin-film analogs of phases in AA2024. Thin films ... -
Electrochemical Behavior of Thin Film Analogs of Mg (Zn,Cu,Al)2
Ramgopal, T.; Schmutz, P.; Frankel, G. S. ( 2001 )The electrochemical behavior of the intermetallic phase Mg(Zn, Cu, Al)2 was studied using thin film compositional analogs prepared by flash evaporation. Characterization by scanning electron microscopy, atomic force ... -
Storage and Release of Soluble Hexavalent Chromium from Chromate Conversion Coatings Equilibrium Aspects of CrVI Concentration
Xia, Lin; Akiyama, Ejii; Frankel, Gerald; McCreery, Richard ( 2000 )The release of soluble CrVI species by a chromate conversion coating (CCC) was monitored quantitatively by ultraviolet-visible spectroscopy. By careful selection of measurement wavelength (339 nm), the CrVI concentration ... -
Pit Growth Study in Al Alloys by the Foil Penetration Technique
Sehgal, A.; Frankel, G. S.; Zoofan, B.; Rokhlin, S. ( 2000 )The foil penetration technique was used to study pit growth in AA1100-O and AA2024-T3. Preliminary work on AA1100-O foils of different thicknesses indicated that the pit growth rate increased with increasing applied ...
