I propose to carry out an electrolytic etch on a stainless steel plate like so:
One of electrodes must be the stainless steel plate which is being etched and the surface layer must be removed.
I'm aware such an electrolytic etches can produce harmful by-products such as Chlorine (NaCl electrolyte), Chromium compounds and more.
If it is possible, What electrolytes and electrodes can I use to prevent the production of these substances?
Would it be possible to create safer Chromium compounds? If I can't, what other non-electrolytic options do I have?
