Cadmium Replacement Using Pulse Plating And Ionic

2018-2-5  good replacement for cadmium needs to be sufficiently sacrificial to protect steel substrates, but not be too electronegative to give an unnecessarily high corrosion rate. Any candidate materials should also be galvanically compatible with both steel and high strength aluminium aircraft alloys. Other important property considerations include hydrogen embrittlement, resistance to aircraft fluids,

Cadmium Plating Alternatives - SERDP-ESTCP

2021-7-30  Cadmium plating is used for two primary purposes: 1. To provide sacrificial corrosion protection to steel components. 2. To provide galvanic compatibility between electronegative materials such as Al and Mg, and more noble materials such as stainless steels. Cd plate is normally chromated with a typical hexavalent chromium conversion coating.
