<p>The invention relates to an electrolyte for electrochemically polishing austenitic steels comprising 60 % phosphoric acid, 20 % sulphuric acid, 3 ... 5g/l modified collagen, 0.1 ... 0.9 g/l isopropanol and 16.9 ... 14.1 % water. Said electrolyte is applied at a temperature of 60 ... 70A C and a voltage of about 14 ... 18 V, and the polishing of the austenitic steel is achieved at a current density of 20 ... 40 A/dm2. According to the invention, after applying said electrolyte the polished surfaces of the pieces have a roughness of 2.3 to 3 less than the initial roughness.</p> |
