For the electrolyte electropolishing of a stainless steel or of a nickel alloy using this electrolyte, and its application to the decontamination

摘要

The invention concerns an electropolishing electrolyte composed of a mixture of glycolic acide, nitric acid and water in the following concentrations: glycolic acid: 152-538 g/kg, nitric acid: 170-568 g/kg, water: 280-678 g/kg. The invention also features a method for the electropolishing of a stainless steel or of a nickel alloy such as an Iconel utilizing this electrolyte, which is particularly useful in the decontamination of surfaces contaminated by radioelements, especially in the nuclear industry.
