NCMS Project #: 141039
Problem: Most ground combat and support systems continue to rely on fasteners plated with Cd/Cr6+ or Zinc passivated with Cr6+. 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.
Benefit: By looking for alternative sources for the coatings, maintenance and sustainment work can be accomplished in a safer environment. The costs savings from disposal of environmentally harmful elements as well as healthcare could add up to a significant amount.
Solution/Approach: ZnNi is a highly effective replacement for Cd/Cr6+ and Zn/Cr6+. It provides similar corrosion protection. This initiative is intended to demonstrate and conduct a proof-of-concept that the industrial base can support a transition to ZnNi plated hardware. The project will test this proof of concept on the Self-Propelled Howitzer System (SPHS) – specifically the M109A6 (Paladin) which is currently fielded. This project will gather information and define the process for maintenance and sustainment transition to ZnNi.
