Abstract
In this research, discharge duration and pulse frequency were studied to determine the optimum conditions for creating a single crater. In addition, the relationships between pulse frequency and the surface characteristics of a whirling electrical discharge texturing (WEDT) processed were determined. It was 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 decreased owing to the removal of protrusions. With honing, the surface roughness of the textured surface expectedly led to a reduced friction coefficient.
