The Robert L. Kersman Award of Excellence for best paper is named for Robert (Buzz) Kersman of Lorin Industries in Muskegon, Michigan, who was instrumental to the formation of the Council, helping to fund and organize the early meetings.
Using Optical Areal Measurement Methods to Assess the Surface Shape and Texture on Aluminum Anodized Surfaces
Andres Arasanz, Niels Schwarz, Aitor Matilla, and Jordi Marine, Sensofar
STERRAD® Testing of Color Anodized Finishes
Mark Jozefowicz, Reliant Aluminum Products
Medical device application of color anodized aluminum requires that the finish withstand multiple sterilization treatments. STERRAD® sterilization subjects parts to a highly oxidative environment that often results in color fade. The results of an investigation carried out on a variety of organic and inorganic colors sealed by six methods using conventional technologies was presented.
Cost Reduction in Anodizing Using New Auto Filter
Stefan Strasser, Lenzing Technik GmbH

Stefan discussed how successful installations of the filter in dyeing and seal-bath sections have proven the above mentioned potential.
Enhancing the Use of Anodized Aluminum by Demonstrating to Decision-Makers the Increased Value of Colored Aluminum in Terms of Surface Properties, Appeal, as well as Cost.
Dr. Klaus Dieter Baumgart, Clariant International AG
His paper challenged the perception that colored anodized aluminum is more expensive and more difficult to process than other materials such as powder coated metals and plastics. Dr. Baumgart explained that when the multi-step process challenges of producing colored anodized aluminum are taken into account from the very first design phase with designers, OEM and brand decision makers, that perception is proven wrong

Electrochemical Kinetics, Transport & Pattern Formation in Anodizing
Dale Barkey, Ph.D., University of New Hampshire
The formation of anodic oxide finish is examined as a far-from-equilibrium electrochemical phase-formation process. In this view, the growth of a highly ordered oxide phase is related to competition among electrostatic and diffusive driving forces, surface kinetics, and spare charges. The framework is compared with published models of oxide growth as well as experimental data from this laboratory.

Rinsewater Reduction Calculator
Warren John Fullen, Boeing Corporation
Regulatory and cost drivers have increased the focus on rinsewater reduction at the Boeing Plant in Auburn, Washington. The first step in making reductions is to determine the amount of rinsewater required for a given process, taking into account requirements driven by health and safety, applicable specifications and part quality. This can be accomplished with the Rinsewater Reduction Calculator (RRC), which uses a Microsoft Access database to model single, double counter current, and triple counter current rinse tanks. Implementing timer settings generated with the RRC in place of subjective practices has reduced rinsewater usage by more than 50%.
