Session 1: Aerospace/Defense Response to REACh

Abstract Number:

3

The audience will see normalized data on the success of a ‎hexavalent chromium free aluminum ‎sacrificial paint. This is an ‎exciting development in the trek to a more environmentally ‎responsible ‎aero industry.‎

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 which are equal to or better than have ‎been difficult. Many attempts have resulted in ‎failure. A body of ‎results will be shared substantiating efficacy of a leading ‎‎replacement. Performance testing includes cyclic-synthetic-sea-‎water (salt spray/humidity/ambient) ‎corrosion testing, continuous ‎neutral salt spray corrosion testing, cyclic salt spray/humidity ‎corrosion ‎testing, cyclic salt spray/heat/humidity corrosion testing, ‎heat resistance testing, fluid resistances ‎testing, adhesion testing, ‎conductivity/resistivity, metallography, quality, stripping, and ‎touch up.‎
