Session 9: Aerospace/Defense/Military Zinc Nickel Advancements
Abstract Number:
95
The audience will benefit from an understanding of how to reduced occupational safety and health concerns associated with exposure to cadmium and cadmium electroplating chemicals through elimination of cadmium, cyanide, and hexavalent chromium through process substitution with zinc-nickel electroplating.

Technologies for Improved Performance or Increased Efficiency
NAVAL AIR SYSTEMS COMMAND (NAVAIR) has recently approved zinc-nickel electroplating as a substitute to cadmium electroplating for high strength steel components commonly associated with landing and arresting gear systems. The qualification effort required a testing program to characterize coating quality, corrosion performance and structural mechanical properties. This data resulted in the development of a new military specification (MIL-PRF-32660) for engineering design. This presentation will discuss material properties, processing, tooling and infrastructure requirements to transition this technology to DoD, OEM and industry manufacturing, repair and overhaul (MRO) facilities for improved coating performance and durability.
