Elimination of Hexavalent Chromium-Cadmium for Sustainment – Phase III

NCMS Project #: 142073

Problem: Transitioning away from Cd/Cr6+ to ZnNi is needed to ensure the safety of commercial operators and maintainers who work regularly on bridges, commercial vehicles and other legacy vehicles. ZnNi is a highly effective replacement for Cd/Cr6+ and Zn/Cr6+. This initiative intends to address the challenges inherent to this transition and the solutions derived will be extensible to the public and across the DOD.

Benefit: By taking the carcinogenic elements out of the workplace both the employee and employer should see a reduction in costs and lost workdays. In addition to environment savings, these coatings can potentially reduce corrosion and reduce the overall maintenance demand across all sectors.

Solution/Approach: Phase III intends to refine and implement the processes developed in previous phases  by conducting a Bill of Material (BOM) analysis across several ground vehicle platforms, developing a list of fasteners that need to be migrated to ZnNi by identifying and defining replacement ZnNi fasteners, and analyzing a baseline cost estimate required to complete the replacement across multiple ground combat vehicle systems.
