摘要

As deposited trivalent chromium and cerium based passivations on electroplated LHE γ-ZnNi can have electrical contact resistance < 5 mΩ/in~2 specification using optimized deposition conditions. The electrochemical response of the as-deposited passivation layers is dependent on the type of material and process used. (1) Cerium based passivations have a single time constant response that implies a simple barrier response. (2) The TCP and CrCC passivations have two time constants that infer an active electrochemical response in addition to being a physical barrier.
