Discharge duration and pulse frequency are studied to determine the optimum conditions for creating a single crater. In addition, the relationships between pulse frequency and surface characteristics using Whirling Electrical Discharge Texturing (WEDT) are determined. It is confirmed that the texture-area ratio and the total removal volume of craters, but not crater diameter or crater depth, can be controlled by adjusting pulse frequency. Moreover, after honing, surface characteristics decrease owing to the removal of protrusions. With honing, the surface roughness of the textured surface leads to a reduced friction coefficient as expected.
