Anodic Aluminum Oxide Formation, Porous Templates, and Corrosion Protection
This community focuses on the electrochemical creation of oxide layers on aluminum and other metals, primarily to produce corrosion-resistant surfaces, nanoporous templates for filtration and sensing, and dielectric materials for capacitors.
The work centers on the anodization process, where aluminum alloys are treated in acidic electrolytes such as sulfuric or oxalic acid to form controlled oxide films. Recurring themes include the fabrication of nanoporous anodic alumina (AAO) membranes with tunable pore sizes, the study of barrier layer properties for electrolytic capacitors, and the enhancement of corrosion resistance in aerospace and industrial applications. The research also extends to the formation of nanostructured oxides on stainless steel and the use of anodic films as substrates for depositing nanowires or other functional materials.
The largest share of the community's output is found in aluminium research, accounting for 3.5% of all aluminium studies, with 1,112 papers in this group. Tantalum research follows with 438 papers, representing 1.3% of that element's tracked literature.
The community comprises 5,160 papers, published most frequently in the Journal of The Electrochemical Society, Electrochimica Acta, and Thin Solid Films.
Recent work continues to focus on the optimization of anodization parameters for creating 3D nanoarchitectures and through-hole membranes, as well as the development of predictive models for the degradation of aluminum electrolytic capacitors.
