Update on Alternatives for Cadmium Coatings on Military Electrical Connectors

摘要

The most promising candidate coating processes to replace cadmium and hexavalent chromium in electrical connector applications are technologies that are already being used on electrical connectors to some extent, or demonstrate both considerable promise for the application and sufficient maturity. These include:rn1. Electroplated aluminum (AlumiPlate~?)rn2. Electroplated alkaline zinc-nickel (5-15% nickel in the deposit)rn3. Electroplated tin-zinc (at least 20% zinc in the deposit).
