BACKGROUND Corrosion protection is critical to long term ejection seat reliability and operation Cadmium plating is used extensively in Propellant Actuated Devices PAD items. PROs Good corrosion protection Thin enough for threads good lubricity. CONs Cadmium plater pool is drying up EPA regulates cadmium in air Cadmium toxic, carcinogenic. OBJECTIVES Find a non-proprietary replacement, low toxicity, plating that provides corrosion protection which is equal to or greater than existing cadmium plating Evaluate our low VOC plating system on the replacement coating Assure that cadmium replacement doesnt induce hydrogen embrittlement Qualify the replacement system.
