Electrical discharge texturing

Advances in engineered surfaces for functional performance

“…17 and 18 show the inkjet printing of a steel surface with parallel gaps and in multi-steps with chevron-like gaps, respectively. Electrical discharge texturing (EDT) [11,181] Micro EDM [46] Electrical beam texturing (EBT) [64] Ion beam texturing (IBT) [54,142] Chemical etching…”

Skin-pass rolling I—Studies on roughness transfer and elongation under pure normal loading

“…Several experimental studies on roughness transfer in skin-pass rolling are noted in literature [5][6][7][8][9], but very few theoretical/ numerical studies related to the subject are found. Applying slipline field analysis Sutcliffe [10] studied separated indentation of a plate with multiple punches.…”

A study on the characteristics of electrical discharge textured skin pass mill work roll

“…Successive discharges at high frequencies produce many randomly placed overlapping craters. The shape and the depth of the craters, which determine the surface roughness of the rolls, depend mainly on the operational parameters such as discharge current, discharge duration, and polarity used [4][5][6]. Compared with traditional shot blasting texturing, EDT allows higher number of peaks at constrained average surface roughness, which can be obtained in a higher repeatability.…”
