didates that may meet the requirements. The findings were then used to derive a path forward to demonstrate/validate the most-promising alternatives for the specific needs and applications of OO-ALC. FUTURE WORK Having established the test methods and acceptance criteria for replacing sodium dichromate sealers, as well as available candidates for testing, the effort will focus on testing and data evaluation. It is anticipated that this work will identify a candidate that can meet the needs of OO-ALC with respect to an anodizing seal. Once this candidate has been identified, thoroughly validated through testing, and recommended for use at OO-ALC, the process of modification of the relevant technical order (TO) for conducting anodizing and sealing operations at OO-ALC will be initiated accordingly. The replacement of sodium dichromate in this application will reduce the environmental burden and increase worker health and safety at OO-ALC. ABOUT THE AUTHORS Rob Mason is a Senior Materials and Process Scientist at Concurrent Technologies Corporation (CTC) in Largo, Fla. In this role, he provides technical support to CTC���s clients in government and commercial industry. His current work includes providing support to inorganic coating activities conducted by the Air Force Research Laboratory (AFRL). Mr. Mason has more than 20 years cumulative experience in surface engineering, coatings R&D, and testing and evaluation methodology development, and has co-authored over 50 technical publications and presentations on these subjects. He earned his B.S. in Chemistry from Fairleigh-Dickinson University, New Jersey. He is a member of the National Association of Surface Finishers (NASF), NACE International, and Toastmasters International. Sarah Clark is an Associate Chemical Engineer at CTC in Dayton, Ohio. Her main responsibilities are providing project management and technical project support to various inorganic coating focused projects. Ms. Clark is subtask lead for the Dichromate Sealer Replacement Subtask of the Inorganic Finishing Technologies Task Order for the AFRL. She is responsible for providing budget management and technical planning, as well as leadership and oversight to the technical staff supporting the Subtasks. Ms. Clark holds a Bachelor of Science in Chemical Engineering from the University of Dayton with a minor in Environmental Engineering. Dr. Melissa Klingenberg is an Advisor Engineer at CTC in Johnstown, Pa. She provides overall support to the Environmental Technologies Discipline with particular emphasis in the laser decoating and inorganic finishing areas. Her primary inorganic finishing responsibilities lie in innovative coating and surface finishing processes, with her areas of expertise being advanced vacuum deposition/surface finishing technologies and plating processes. Dr. Klingenberg received a B.S. in Chemistry and engaged in post-baccalaureate studies in biology at the University of Pittsburgh at Johnstown. She received an M.S. in Manufacturing Systems Engineering at the University of Pittsburgh and a Ph.D. in Materials Engineering at the Pennsylvania State University. Dr. Klingenberg has been an active member of NASF since 1994, and has presented and/or written numerous papers for NASF and AESF events and publications. Dr. Elizabeth Berman is a Senior Research Engineer in the Materials & Manufacturing Directorate of the AFRL at Wright-Patterson Air Force Base, Ohio. She has 17 years expe381
