Session 1: Aerospace/Defense Response to REACh

Abstract Number:

23

The research and development of any coating system is time ‎consuming and fraught with ‎failure. When success is achieved in ‎an area as challenging as the aerospace industry demands, it is ‎‎valuable to summarize and reflect on the process. ‎

Topics:

Aerospace/Defense/Military

Hexavalent Chromium is a known carcinogen, repro-toxin, and ‎mutagen. Its elimination is of high importance to the aerospace ‎industry which has struggled to find high performing ‎alternates. Legacy aluminum sacrificial paints have traditionally ‎utilized hexavalent chromium to prevent corrosion and oxidation ‎of steels. Due to the high performance nature of these coatings, ‎work to approve alternate coatings have been difficult. Many ‎attempts have resulted in failure.‎
The process of developing a novel hexavalent-chromium-free ‎aluminum sacrificial paint will be summarized. The history, ‎failures, and key factors will be summarized. This presentation is ‎intended to be tandem with the Rolls-Royce presentation on the ‎testing results of this novel coating system.‎
