Abstract
An investigation of the effect of the addition of certain ‘surface-active’ materials to electrolytes used in electrochemical machining was undertaken. Concentrations of only a few parts-per-million of additive affected the flow rates of the electrolyte, the settling rates of the reaction products and the dissolution of the anode. It was found that electropolishing of Fe in NaCl solution could be brought about although dissolution efficiency was reduced. The additives, however, were found to mechanically degrade under high turbulence; a dis-association mechanism for the degradation is suggested.
