ABSTRACT:
Electrochemical machining of ceramic particulate and metal matrix surfaces, and of other uneven or discontinuous surfaces, is conducted using an electrode which has a porous metal working face. Relatively low electrolyte pressures of the order of 5 kPa and low flow rates of the order of 6 ml/s/cm.sup.2 of electrode surface are used. Preferably the electrode face is made of sintered powder. Facing the electrode upward and the workpiece surface downward enables machining of workpieces without unwanted flow of electrolyte onto areas away from the machined surface.
