Abstract


Changing environmental regulations, market needs, and materials of construction continuously drive the evolution of aerospace coatings and application processes. Boeing actively pursues a continuous improvement strategy for its products to meet these changing demands. This strategy is based on extensive internal R&D programs as well as significant collaborations with suppliers, universities, as well as small and large businesses. This paper will review some challenges involved in developing new, more environmentally friendly coatings and will focus on current approaches to eliminate hexavalent chromium in future coating systems and processes.
