Or is this very different from the hot salt baths I'm thinking of that are typically used for heat treat?
It's the following...
Distilled water with Sodium Carbonate and Potassium Sodium Tartrate. I believe I have that all figured out. Now I need to figure out how to determine the volts and amps to the surface area of the parts I'm stripping. Does anyone know what the formula is for determining this?
4-6V DC & a current density of 4-8A/in^2 is the suggested control limits per AMS 2448. Some specifications just give a requirement of 4-6V with no specific current density.
Also heating the tank to 140-150 would probably help dissolve the hardened constituents at the bottom. 140-150 is the recommended operating temp during stripping to keep the salts in solution
