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.‎

Topics:

Aerospace/Defense/Military
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.‎
