Abstract
An article for texturing an electrode having a tip hardness and a tip contour is disclosed. The article includes a plate having an upper surface and a lower surface, and an indentation in at least one of the upper and the lower surface. The indentation includes a textured surface having a plurality of asperities. The textured surface has a hardness greater than the tip hardness of the electrode. The texture of the textured surface is imprinted into the tip of the electrode in response to the tip of the electrode and the textured surface being pressed against each other.

An article for texturing an electrode having a tip hardness and a tip contour, the article comprising:
- a plate having an upper surface and a lower surface;
- and
- an indentation in at least one of the upper and the lower surface, the indentation having a textured surface comprising a plurality of asperities, the textured surface having a hardness greater than the tip hardness of the electrode;
- wherein the texture of the textured surface is imprinted into the tip of the electrode in response to the tip of the electrode and the textured surface being pressed against each other;
- wherein each of the plurality of asperities are disposed at the textured surface so as to traverse concentric circular paths in response to rotation of the plate about an axis perpendicular to the plate.
A method of texturing an electrode having a tip hardness and a tip contour, the method comprising:
- placing a tool between a first electrode and a stop surface, the tool having an upper surface and a lower surface, an indentation being in at least one of the upper and the lower surface, the indentation having a textured surface comprising a plurality of asperities, the textured surface having a hardness greater than the tip hardness of the first electrode;
- pressing the first electrode against the tool such that the tip of the first electrode is pressed against the textured surface of the tool, thereby imprinting the texture of the textured surface into the tip of the first electrode;
- and
- reversing the pressing action and removing the tool from between the first electrode and the stop surface.
