Implication

Theoretical modeling study reveals mechanisms linking anodization parameters to pore geometry in aluminium, indicating determinants of stationary porous oxide growth.

Key Points

To formulate a theoretical model describing porous oxide structure formation and stationary pore growth during the electrochemical anodization of aluminium.
Formulated coupled transport and reaction equations incorporating anodic oxide growth across both oxide/electrolyte and oxide/aluminium interfaces.
Integrated electrochemical and field-enhanced dissolution alongside a three-dimensional electric field and current distribution in the scalloped barrier oxide layer.
Derived analytical expressions for stationary pore growth to evaluate relationships between internal electric fields, pore geometry, and process variables (applied voltage, temperature, and electrolyte pH).
Established analytical relationships directly linking pore geometry and barrier oxide electric fields to applied anodization voltage, temperature, and pH.
Demonstrated qualitative and quantitative consistency between the derived analytical expressions and existing experimental anodization measurements.
