We learn about the electrochemical processes that cause galvanic corrosion when two different types of metal are electrically connected and immersed in an electrolyte.
New!
We discuss how to minimize the risk for corrosion by choosing the right materials, surface coatings, and construction methods.
New!
We explore how to use a bonding system and sacrificial anodes to keep corrosion at bay. We also briefly look at impressed current systems.
New!
Stray-current corrosion can be much worse than galvanic corrosion. We examine various examples of stray-current corrosion and how you can minimize the risk on your boat.
