Preventing corrosion by attaching a aluminum plate?
If someone suggested attaching a titanium plate to an steel structure immersed in seawater, what might they be trying to achieve?
I was thinking simply a protective coating, because titanium is not very reacture, and so could not act either as an inhibitor or as a sacrifical anode, but that seams really stupid, so i doubt anyone would actually have done it.
In this case the steel would corrode, acting as an anode, while the titanium acts as a cathode, right?
umm, isn't the material undergoing oxidation the one that corrodes? because the atoms turn to ions and electrons? and reduction is where material builds up? or am i missing something?
I really am not familure with all of Titanium's properties. I did find a referance to it being very resistant to corrosion from sea water, so if it were to be used as a outer layer on the submerged steel, it could according to theory protect the steel from corrosion. This assuming it was applied in a manor to keep all sea water from reaching the steel. They may as well just skip the steel and build the structure out of Titanium alone as try that.
You are correct in it not being a anode, a good cost effective anode for a submerged structure is a magnesium anode.
I can't find a chart showing the electrical voltage potential of Titanium, but assume it it low on the scale because it is referred to as highly corrosion resistant. Normal carbon steel is in the -400mv to -600mv range, magnesium is about -1700mv aluminum is about -1400mv so the higher the voltage potential the product will be a anode to the smaller number.
Your question title mentions aluminum, that would be a anode to steel, but the body of the question talks only about Titanium, so I tried to address the question as Titanium.
