The invention relates to a micro-nano electrochemical deposition
machining method based on a
liquid drop Taylor cone, and belongs to the technical field of micro-
nano manufacturing. The method comprises the steps that liquid drops containing deposited
metal ions are firstly put between a
metal probe and a workpiece, and the materials of the probe are deposited materials; the probe and the workpiece are both immersed in an insulating medium, and the insulating medium and water are not compatible; the probe and the workpiece are connected with the positive pole and the negative pole of a direct-current power source respectively; the liquid drops do
reciprocating motion between the probe and the workpiece under the action of an
electric field; and when the liquid drops are close to the probe and the workpiece, the
Taylor cone is formed on the surfaces of the liquid drops under the action of the
electric field, by means of the electrochemical action generated during contact of the
liquid drop Taylor cone, the probe and the workpiece,
metal atoms of the metal probe are changed into metal cations to enter the liquid drops, then the metal cations are carried by the liquid drops to the surface of the workpiece and conveyed to the surface of the workpiece through the
liquid drop Taylor cone, the metal cations obtain electrons on the surface of the workpiece to be changed into atoms to be deposited, and therefore micro-nano electrochemical deposition
machining is achieved.
