How does oxidation of aluminum make it corrosion resistant?
Aluminum has a very high affinity to oxygen. When a new aluminum surface is exposed in the presence of air or any other oxidizing agent, it quickly develops a thin, hard film of aluminum oxide (or hydrated oxide in non-stagnant water). This aluminum oxidation is precisely what makes aluminum so corrosion-resistant.
What happens to aluminum hull in salt water?
them in salt water the least noble or anodic metal will begin to corrode. Aluminum is extremely anodic and the selection of fasteners, wire, fittings etc is very important. The purpose of a zinc anode is to allow the anode to corrode before the aluminum hull.
