Abstract
The impact of reactions at the various interfaces in the developing oxide structure are explored: the substrate-oxide boundary, the oxide-electrolyte boundary, and along the knitlines in the oxide structure, as they affect oxide growth during the anodizing process. Reactions of various microstructural features and defects at the substrate surface are discussed in terms of Surface Activation Polarization effects and Concentration Polarization effects, to further explain why some react by way of the process parameters to form anodic oxide and some do not, while others confound the process causing side reactions to occur. The impact of various interfacial phenomena changes in the oxide structure can be determined using the corrosion model for the anodizing process based in the Tafel Equation, introduced in Chap. 5, and is further developed in this chapter.
