Deanohh,
I work on a lot of small craft at my friends shop and own boats of my own. Sacrificial zincs on boats and outboards, outdrives, etc. work because they have a medium for current flow, i.e. water. The zincs do nothing for corrosion when the boat or motor is out of the water.
There are a number of corrosion processes. Corrosion control is a BIG DEAL in aviation and there are no zincs on any Naval aircraft that I have ever seen as they just wouldn't work. OK, seaplanes, I've never seen one...
Google corrosion types. It will be an interesting read. There are many types.
