AF Cr(VI) Minimize Roadmap: Phase 1 Results

Abstract

Hexavalent chromium is widely regarded as the highest performing corrosion control treatment for aluminum components. However, due to serious environmental and health risks related to its use, regulations regarding hexavalent chrome exposure are becoming increasingly restrictive. In response, DoD acquisition chief, John J. Young, Jr., published a memo in April 2009 directing all Services to use hexavalent chrome substitutes whenever possible. Yet in many weapon systems, its use has continued due to the lack of chrome-free substitutes able to meet MIL-SPEC requirements and laboratory testing. Hexavalent chrome continues to be used in primers, coatings, and sealants across the Services and aerospace industry. This presentation will discuss efforts the Air Force has already made and its current course in finding suitable replacements for hexavalent chrome.
