Nanopore formation dynamics during aluminum anodization
In this paper it is analyzed the nanopore phenomenon which appears during aluminum anodization. The main framework is related to nonlinear partial differential equations of Kuramoto-Sivashinsky type, which describe the dynamics of metal-oxide and oxide-electrolyte interfaces. The approximate evolution equations are derived from the electrochemical anodization model, that represents the potential field governed by a Laplace equation with nonlinear boundary conditions at the moving oxide-electrolyte and metal-oxide boundary interfaces, by linearizing the boundary conditions while maintaining the homogeneous solution. Several numerical examples illustrate the abstract results established in the present paper.
