Corrosion also requires an electrolyte to provide a path between anode and cathode. So if kept in dry air these parts would experience little to no corrosion. If submerged in sea water the corrosion rate would be higher.

It also depends on the contact arrangement and relative component sizes of the two metals, and there is a lot of complexity with corrosion locality. Wide area corrosion is often acceptable at low rates depending on the application, but even small amounts of highly localized corrosion can be structurally devastating.

Exactly.Working with marine environments. It's a major factor when selecting fasteners. You don't want the fastener corroding sacrificially to the plate. Ya know?
