	abstract = {<p>Summary A facile nonsubjective method was designed to measure porous nonconductive iron oxide film thickness using a combination of a focused ion beam (FIB) and scanning electron microscopy. Iron oxide films are inherently nonconductive and porous, therefore the objective of this investigation was to optimize a methodology that would increase the conductivity of the film to facilitate high resolution imaging with a scanning electron microscopy and to preserve the porous nature of the film that could potentially be damaged by the energy of the FIB. Sputter coating the sample with a thin layer of iridium before creating the cross section with the FIB decreased sample charging and drifting, but differentiating the iron layer from the iridium coating with backscattered electron imaging was not definitive, making accurate assumptions of the delineation between the two metals difficult. Moreover, the porous nature of the film was lost due to beam damage following the FIB process. A thin layer plastication technique was therefore used to embed the porous film in epoxy resin that would provide support for the film during the FIB process. However, the thickness of the resin created using conventional thin layer plastication processing varied across the sample, making the measuring process only possible in areas where the resin layer was at its thinnest. Such variation required navigating the area for ideal milling areas, which increased the subjectivity of the process. We present a method to create uniform thin resin layers, of controlled thickness, that are ideal for quantifying the thickness of porous nonconductive films with FIB/scanning electron microscopy.</p>},

	abstract = {Coatings formed on 2024-T3 aluminum alloy were studied by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) after dipping in zinc phosphating (ZPO) baths at different acidities, for different lengths of time, and with or without Ni2+ additive. The overall objective was to learn more about the role of Ni2+ on the ZPO coating mechanism, particularly since this additive is believed to improve corrosion protection for the Al alloy. Secondary phosphates dominate the coatings when the Ni-containing solution is adjusted to starting pH values of either 3 or 5, while tertiary phosphate is predominant at pH 4. AlF3 precipitates during the early stages of the coating process. Ni2+ has two main roles in the mechanism. First, the rate of increase in local solution pH is retarded by the slower kinetics of reactions involving Ni2+ compared to Zn2+,leading to thinner ZPO coatings when Ni2+ is present in the coating solution. Second, most Ni2+ deposition occurs during the later stages of the coating process, by nickel phosphate deposition and/or by formation of a Ni-rich oxide. (c) 2006 Elsevier B.V.

	abstract = {Coatings formed on 2024-T3 aluminum alloy were studied by scanning electron microscopy (SEM) and scanning Auger microscopy (SAM) after dipping in zinc phosphating (ZPO) baths at different acidities, with or without the Ni2+ additive. The objective was to learn more about the ZPO coating mechanism on the different microstructural regions of 2024-T3. When the initial coating solution pH is 4 (optimal acidity), a slower etching rate at the Al-Cu-Fe-Mn intermetallic particle{\textquoteright}causes significant precipitation of ZnO, which differs from the coating on other regions of the surface where phosphate predominates. The larger crystals (similar to mu m dimension) on the matrix and the Al-Cu-Mg particle contain more phosphate compared to other areas on the surface. When Ni2+ is added to the coating solution, the Al-Cu-Mg particle is more thickly coated compared to when the Ni2+ is not present. The slower rate of precipitation when Ni2+ is present in the coating solution increases the exposure of the alloy substrate to the acidic environment, so allowing more dissolution of Mg and Al from the Al-Cu-Mg particle. This results in the particle becoming more cathodic in nature, and therefore more coating deposits at this location. Evidence from SAM supports the presence of NiAl2O4, hypothesized in Part I, forming at coating pores later in the process. (c) 2006 Elsevier B.V. All rights reserved.},

	abstract = {Dilute chromic acid and the organosilane bis-1,2-(triethoxysilyl)ethane (BTSE) were compared by their abilities to act as post-treatment rinses for samples of 2024-T3 aluminum alloy, which had previously been coated by zinc phosphate. The first approach is conventionally used to improve corrosion protection, but alternatives are needed because of environmental concerns with Cr(VI). Variations in conditions for application of the final rinse, especially through changes in solution concentration, were compared by measuring polarization curves, which provide an indication of corrosion stability. These comparisons were related to coating morphology, which was studied using scanning electron microscopy (SEM), and to studies of chemical composition with X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray (EDX) spectroscopy. Immersion tests in NaCl solution were applied to post-treated zinc phosphate coatings that had been formed on mirror-polished alloy surfaces. Overall, the post-treatment in 4\% BTSE at 25 degreesC appears to provide a comparable corrosion resistance to that found when the final rinse is done in a conventional CrO3 Solution (concentration 0.5 g/l) at 70 degreesC. At the microstructural level, initial observations were also made for comparing the effects of the post-treatments at protecting alloy matrix areas adjacent to Al-Cu-Mg second-pbase particles.
