Critical Factors for the Transition from Chromate to Chromate-Free Corrosion Protection

Abstract

Because of increasing regulatory pressure to eliminate chromium from surface finishing, the Department of Defense (DOD) and Department of Energy (DOE) have committed to replace chromate-based metal finishing in present and next generation systems. At issue is whether this change will occur in a timely manner without performance or cost penalties that could compromise operational readiness. Additionally, undue delay in determining and implementing new corrosion protection practices poses enormous risk for existing assets. To facilitate this transition an understanding of important functions of chromate corrosion protection that must be replicated in new surface finishing methods is needed. This study was carried out to address those needs.
