hello,

I am preparing a galvanic corrosion test between titanium and stainless steel. While reviewing articles focusing on the experimental procedures for galvanic corrosion between dissimilar metals, I noticed that one common method involves drilling a hole into the electrode (in my case, titanium) , connecting it to a copper wire, and then masking the electrode to expose only a defined surface area.

I have two questions regarding this setup:

Any guidance or reference would be greatly appreciated.
