Galvanic corrosion refers to a type of
- corrosion between two pieces of material.
- electrochemical plating process between metal layers.
- uniform surface corrosion across the exposed area.
Explanation from PART66Online
Galvanic corrosion is an electrochemical attack that occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, the less noble metal corroding preferentially. It is therefore corrosion between two materials, not a deliberate plating process or the even surface attack that characterises uniform corrosion.

"two pieces of material" - this is a sloppy question - one piece of "material" could be plastic and the other metal!

this isnt sloppy,galvanic corrosion or electrochemical as it is also called,to happen needs 2 things:1 2 different pieces of material and secondly the presence of an electrolyte.
