The Behavior of Intermetallic Compounds in Aluminum during Sulfuric Acid Anodizing, Part 1: Al-Mn, Al-Fe, Al-Mg2Si, Al-Cr Alloys

The 1971 Carl E. Huessner Gold Medal Award was given to J. Cote and co-workers for the Best Paper appearing in Plating or the AES Technical Proceedings in 1970. Actually a two-part paper beginning in 1969, the first installment of the paper is republished here in a series on the AES/AESF/NASF Best Paper Awards. Their work presents very important work on how the anodizing process reacts with the other materials alloyed in with commercial aluminum grades.

Sulfuric / Organic Electrolytes and Total Quality Improvement (TQI) for Present / Future Anodizing Requirements

After the last 12 years of developmental improvements and successful operation in production and selective brush anodizing, we present formulations for the new revised three-part organic acid blend. This ionic active blend detailed here can benefit all sulfuric anodize electrolytes to meet today's more demanding quality, specifications and production requirements.

New Selective Brush / Cell Anodizing Technology Using Sulfuric / Organic Mixed Electrolytes for Dimensional Restoration of Difficult Alloys

This paper presents new innovative problem-solving technology for Type I, II and III selective brush and repair cell anodizing.  Discussions include: (1) anodizing difficult alloys (2000/7000 series) without burning; (2) unique amino complex organic acid protection of the aluminum/anodize surface during processing and (3) high speed anodizing in selective cell operations, including heavy thickness anodize repair procedures.

Nanoporous Anodic Oxides: Fabrication, Applications, Sensing and Biosensing

Numerous metals are subjected to anodic oxidation. As a result, one can obtain amorphous barrier-type oxides, crystalline barrier-type oxides or amorphous nanoporous oxides. This paper provides details of sensing techniques and recent advances in the development of NAA-based sensing and biosensing technologies.

Nanostructure of Porous Anodic Aluminum Oxide: Advances in Surface Engineering

Porous alumina membranes of anodic aluminum oxide (AAO) are widely used for the fabrication of various nanostructures and nanodevices.  Over the last decade, nanowires, nanotubes and nanodot arrays, have been fabricated by the deposition of various metals, semiconductors, oxides and polymers inside the pores of AAO membranes.  These structures are produced by changing the anodization conditions, during electrochemically self -ordering of AAO.  One can obtain amorphous barrier-type oxides, crystalline barrier-type oxides or amorphous nanoporous oxides, but fabricating binary nanostructures is challenging.  Here, we review methods to  achieve diverse binary nanostructure arrays, including material, dimension and morphology.
