The Influence Of Bipolar Electrochemical Cell Geometry On The Studies Of Pitting Corrosion, Amin Kazem Ghamsari
USF Tampa Graduate Theses and Dissertations
Bipolar electrochemistry (BPE) is a technique that provides a wireless alternative totraditional electrochemistry to elicit redox reactions. It has been utilized in different applications, including studying localized corrosion, gradient electrodeposition, propulsion of micromotors, and water treatment. The popularity of the method is not solely dependent on its wirelessness but more due to the simultaneous presence of cathodic and anodic poles on the same surface, which also begets its name as bipolar. The concept of the method is based on the polarization of conductive objects in an electric field in the presence of an electrolyte. In BPE, instead of controlling the …
Impedance Analysis Of Anodized Aluminum And Structural Bridge Tendons, Justin Silnutzer
Impedance Analysis Of Anodized Aluminum And Structural Bridge Tendons, Justin Silnutzer
USF Tampa Graduate Theses and Dissertations
This is a two-part thesis with the overall investigation technique being electrochemical impedance spectroscopy (EIS). In the first part, EIS is used to estimate the layer thickness of anodized aluminum oxide. This required the development of an appropriate electrical circuit model; that with parameters that correspond to physical properties of the oxide. In this work, it was found that for thicker oxides of which the outer porous layer is greater than 12 microns, impedance may be used to estimate the outer layer thickness. However, further research is required to understand the role of outer porous layer structure on the impedance …
