Hello,
I found a method for small-scale electropolishing:
Variable DC supply, 0-24V to 1A
Solution of 60% phosphoric acid, 20% sulphuric acid, and 20% water as
electrolyte. Stainless rod to serve as cathode, part to be polished
attached to anode. Start with 100 mA for a few seconds; inspect part
with magnifier.
I was proposing to use a variac with a 120V to 24V transformer and a
simple bridge rectifier with appropriate capacitors... Set whatever
voltage gives me 100 mA using the variac. Does anyone have any
experience doing this on a small scale? Any electropoloishing tips
and tricks would be greatly appreciated. Thanks for your help!
