Abstract
1427394 Electropolishing copper or copper alloy POLITECHNIKA WARSZAWSKA 13 April 1973 18015/73 Heading C7B In a method for the continuous electropolishing of an element made of Cu or an alloy of Cu (e.g. a beryllium bronze wire or a Cu wire), the element is passed through first and second baths containing the same solution; namely a solution containing H 3 PO 4 having a concentration of 75 to 90 wt per cent, and Cu ions having a concentration of 0À05 to 2 gram-ions/litre, and an addition of one or more organic compounds (such as aliphatic alcohols, tertiary aliphatic amines, and/or alkyl ammonium compounds). In the first bath there may or may not be a current density on the element. In the second bath a voltage of between 1À5 and 2À5 volts is applied between the element (as anode) and a cathode. The first bath solution has a constant temperature of 70‹ to 100‹C and the second bath solution has a temperature of 10‹ to 30‹C at the 'inlet' increasing to 60‹ to 140 C at the 'outlet'. The inlet and outlet are the points at which the element enters and leaves the second bath. The electropolishing may be carried out using a constant potential or a constant current.
