Abstract
A discharge coating apparatus comprises an assembly for applying a vibrational motion in the longitudinal direction of an electrode while applying a voltage pulse in synchronization with the vibration to cause electrical discharge between the surface of a workpiece and the electrode and the formation of a coating layer on the workpiece of the material of the electrode due to the heat produced by the electrical discharge. An additional motion is applied to the electrode to cause the electrode to undergo reciprocal travel towards and away from the suirface of the workpiece at an angle relative thereto. The additional motion can be a rotational motion. The electrode can be formed with a concave portion at its tip or with an axial bore so that only an annulus of the electrode contacts the workpiece. The additional motion can be a skipping movement by utilizing a skipping mechanism consisting of an elastic memebr.
