Production of Micro-holes on Duplex Stainless Steel 2205 by Electrochemical Micromachining: A Grey-RSM Approach

Electrochemical micromachining (ECMM) is a non-traditional micro-fabrication technology developed to produce complex geometries on very hard and electrically conducting surfaces. Typical applications of ECMM include aerospace components, medical devices and gas turbine blades. Duplex stainless steel 2205 (DSS 2205) is an exceptional corrosion-resistant iron alloy with a nearly identical volume of austenite and ferrite. In the present work, ECMM...
