Zinc Nickel Dip and Brush Plating

August 17, 2017, Time: 11 am CDT
Type: Event

Cadmium has been widely used in the aerospace industry and the Department of Defense (DoD) due to its excellent corrosion resistance, adhesion, and lubricity characteristics. However, cadmium is a toxic metal and human carcinogen and is heavily regulated in the United States and the European Union. The aerospace community has spent years and a significant amount of money developing technologies to replace cadmium in plating and brush plating processes for aerospace parts and critical structural components. Replacing cadmium in plating and brush plating processes has proved technically challenging and has left many in the community accepting the health and environmental risks associated with cadmium. However, recent developments with zinc nickel formulations are a significant step forward in the elimination of cadmium. The new Low Hydrogen Embrittlement zinc-nickel (LHE Zn-Ni) process enables aerospace manufacturing to meet environmental restrictions by replacing cadmium plating. LHE Zn-Ni is applicable to major structural components of aircraft, such as landing gear, as well as consumables such as pins, bearing, bushings, and bolts. Zinc-nickel brush plating can be also used to repair worn and corroded parts, in many cases while the components are still installed on the aircraft.
