Electrochemical Deburring of Molybdenum, Aluminum and Stainless Steel

Abstract:

Sharp edges left after chemical milling and blanking are presently being mechanically removed at high cost. The sharp edges would be areas of high current density in electrochemical operations and could be easily removed in electrochemical l solutions. The criteria of a good electrochemical deburring solution were leveling characteristics and removal rate. Various solutions were evaluated for breaking sharp edges on molybdenum, among them being 25 percent by weight nitric acid, nitric-hydrofluoric acid solution for milling molybdenum and variations of Turco 105 steel etchant. These solutions were successful in a leveling action on sharp burrs, but would not round the side edges. A combination of nitric acid leveling and side edge burnishing produced the most promising results. Aluminum and stainless steel deburring was evaluated in proprietary solutions, with good results obtained in polishing and breaking of sharp edges.
