Electrochemical Reduction of Industrial Baths Used for Electropolishing of Stainless Steel

Table 1

Presentation of the gloss and weight of samples “as received” and samples electropolished in a bath without ER and with ER (EP process parameters: t = 45–180 min, I = 1.75 A, i = 0.05 A·cm⁻², q = 2.25–9.00 Amin·cm⁻², and T = 55°C).
