Navy Successes and Challenges in Cr6+ Minimization

Abstract

Naval Aviation Enterprise Position on Cr6+ and Path Forward. Cr6+ is used in 10 major metal finishing and corrosion protection processes, with many sub-processes. Cost impact is highest for compliance when removing Cr6+ containing coatings, especially sanding at FRCs. Application of most materials can be achieved while complying with regulations. Alternatives can be implemented during design and production by OEMs and subcontractors and at Navy and contractor facilities which carry out O, I and D-level maintenance. Many uses include critical engineering applications including adhesive bonding, wear surfaces and corrosion protection on high-strength steels, and protection of critical structure. Compliance with memos and expected DFARs contract language will increase cost of acquisition environmental and corrosion support. Implementation of alternatives is not trivial and requires a risk reduction approach, especially for primers. RDT&E needs to be prioritized and linked to Cr6+ goals.
