The title question is a bit incomplete:What maximum current is expected platinized Pt-electrode per area? I'm not very educated in electro chemistry, but have been study both chemistry and physics. I'm thinking of the variables within this question, among more it may depend on what's in the solution. But I was more thinking of what would happen if the amperage was very high in a Pt-electrode; could this ever get erosion? I believe that if the current is too high relative to its area, this would only get heated. Correct me if I'm wrong.

An example of this electrode is:

You get also physical damage of the electrode in long therm,, because of development of hydrogen or oxygen, depending using as cathode or Anode. Its a kind of of cavitation effect.

Ok, cavitation effect, like propellers are exposed to. In examples you have seen, has it been question about hours, tens or hundreds of hours?

[Hunter2]

Some hundred of hours I would say

Ok, well I think I try my reaction with graphite electrodes, they were very cheap. If it's about hundreds of hours, I think my Pt-electrodes are damaged after a while. They are relatively expensive in comparism to graphite, so I give the latter a try. Thanks for your comments.
