Galvanic area effect/proximity
Galvanic area effect/proximity
(OP)
I have a general galvanic corrosion question, I'm early in the design phase so I have no firm details as yet. I know a large anode/small cathode is ideal, but in general will the anode corrode faster at the contact point with the anode (e.g. a steel housing with a Ti connector body) or will the low electrical resistance of the anode allow for a more uniform corrosion of the anode ?? My thoughts are there will be little or no difference, am I right ?
Thanks for any input.

Are the two items connected? good contact? is there a seal or gasket?
What about the conductivity of the electrolyte?
In general there will be more attack next to the contact. If there is fluid under the connection then you are really screwed.

I wouldn't recommend a threaded connection.
