Wear Through Gold Plating Can Give Salt a Path into Connector Base Metal

What the evidence preview establishes

Sodium chloride attacked worn contact regions where gold was removed and nickel or base metal was exposed. Corrosion then traveled beneath the plating and deeply into the connector metal.

Why this case matters

Evaluate connector corrosion as an interaction between environment and worn plating. Map salt, wear tracks, exposed layers, and subsurface attack before blaming nominal plating thickness alone.
