Plasma Electrolytic Oxidation (PEO): A High-Performance Coating for Light Metal Alloys
Plasma Electrolytic Oxidation (PEO) offers an innovative approach to high-performance coatings for light metal alloys, providing superior alternatives to traditional hard anodizing. The process transforms the surface of metals like Al, Mg and Ti into a robust oxide layer with customizable properties, tailored for demanding applications in aerospace, semiconductor, and industrial manufacturing.

Polarization and Natural Order - The 56th William Blum Lecture
This paper provides an overview of the parallels between the synthetic order established by non-equilibrium reactions, such as anodizing, which are nano-scale, and the natural order established by equilibrium reactions in nature, many of which are on the macro-scale.

Practical Observations in Surface Chemistry and Boundary Layer Control to Enable Scalable Electrochemical Operation - The 57th William Blum Lecture
This paper is based on the 57th William Blum Memorial Lecture at SUR/FIN 2023, in Cleveland, Ohio on June 8, 2023, by Dr. Tim Hall, recipient of the 2023 NASF Scientific Achievement Award. It focuses on the practical effects of controlling the boundary and surface chemistry on a wide range of electrochemical applications. After a brief introduction to the concept and principles of surface and boundary layer properties during electrochemical processes, the use of this approach in controlling various physical properties during electroplating and electrochemical finishing is discussed, including controlling coating stress and metal composition, as well as enabling simple water-based electrolytes to polish passive or complex materials.
