| Abstract Scope |
This study explores oxide layer optimization in anodized AA6061 by combining Taguchi experimental design with FEM simulation. Samples were anodized in oxalic and sulfuric acids under systematically varied voltage, time, concentration, and temperature. SEM analysis at high magnifications enabled pore size, density, and oxide thickness measurements via ImageJ analysis. These outputs were correlated with COMSOL Multiphysics simulations using the Secondary Current Distribution interface. The model incorporates polarization data to evaluate local current density and oxide growth under varying anodization conditions. Control samples were used to calibrate field–thickness relationships and validate simulation results. By coupling pore-level insights with field-driven oxide growth predictions, we identify parameter domains favoring uniform anodic films. Also, this study offers a structured approach to link experimental pore characteristics with localized electrochemical fields, supporting rapid optimization of anodization conditions for nanoscale engineering. |
