Electrochemical and laser micromachining of dual phase duplex stainless steel 2205

Abstract

The micro/nano-manufacturing sector has been particularly influenced by the revolution in electronics. As a result, the use of conventional machineries in micromachining is gradually fading away due to the challenges associated with the high tool wear rate, insufficient machining rigidity, high vibrations, difficulty in removal micro-level chips, higher heat generation, and induced stress in the workpiece. Researchers around the world are currently studying several non-traditional machining techniques with a view to effectively implement them in manufacturing industries, accounting for the rapidly increasing demand for micro parts. newlineThe most popular grade of duplex stainless steel is 2205, which has several advantageous characteristics that are shared by ferritic and austenitic steels. Stainless steel has an exceptional resistance to corrosion because of the large amounts of chromium and molybdenum that it contains. Heat exchangers, pressure vessels, tanks, tubes, and pipes are constructed out of grade 2205 steels. Micromachining applied to fields such as medicine, robotics, photonics/optics, and aerospace engineering. newlineElectrochemical Micromachining (ECMM) is a non-traditional micro fabrication technology developed to create complex contours on tough and electrically conducting surfaces. ECMM applied to aerospace parts, medical instruments, and gas turbine blades. Duplex stainless steel 2205 (DSS 2205) is a unique corrosion-resistant iron alloy with a nearly identical volume of austenite and ferrite. In the present work, ECMM employs to produce a series of thorough micro-holes on a DSS 2205 sheet. Electrode materials for micro-hole making experimentations involve the usage of Brass and Copper Tungsten alloys. newline
