“…Maddu J et al [34] reported a 20 μm thick copper coating with a conventional copper electrode and optimized the process parameter with grey relational analysis, and the result shows micro-cracks, coating thickness, and material deposition increases with the increase in current and pulse duration. Muralidharan B et al [35] experimentally investigate electric discharge deposition using a solid electrode with magnetic field, and the results show deposit increased by magnetic field effect. Khan MY et al [36] explain about EDC process and gives an overview on Coating with different types of electrodes, especially Coating with solid electrode.…”

Electric discharge coating (EDC) process is a competitive surface coating technology that alters the desired surface characteristics. EDC process deposits the material on the substrates from the sacrificial electrode by spark erosion process with the potential advantage of depositing any materials. This paper extensively reviews the work carried out in the EDC process and suggests areas of improvement for easy adaptability in industrial applications. Here, the variants of the EDC process, the route map for process parameter selection, the advantage over conventional methods, and coating characterization are discussed. The review sequentially presents the fundamental process, detailed analysis of tool and workpiece materials used, process parameters, and applications. EDC process has continued to be a key solution for many industrial needs, with the critical advantage of enhancing the substrate's serviceability and protecting against corrosion, thermal stress, and other adverse environmental conditions. The scope of the work is discussed in detail, with potential industrial and biomedical applications suggesting avenues for researchers and industrialists.

“…Very few literature are available to exhibit the significance of input process parameters on the deposition performance. 15 In this work, experiments are formulated by the design of experiments (DOE). CCD is one of the alternative methods to the factorial design for designing the experiments, reported by Box and Hunter.…”

“…So this idea of material transfer can be further developed to create microfeatures by additive process. Researchers 13–15 reported a layer formed by the EDD process and studied the influence of significant input parameters on the deposition process. In the present research work, attempts have been made to develop and enhance the deposition mechanism.…”

“…Literature 19–21 shows that the application of magnetic field is used in the welding research areas, to increase the quality of welding by confining the plasma discharge. From the EDAX compositional analysis of Muralidharan and Chelladurai 15 along with the tool material deposited, the inclusions of carbon and oxygen are also observed over the workpiece in the EDD process with air as the dielectric medium.…”

The requirements of microfeature-based systems are essentially increasing due to their usage in every major field. Market needs microproducts with more functionality, information processing ability integrated together with compact size. Electro-discharge deposition process is an emerging nonlithographic, additive process to manufacture high aspect ratio 3D microfeatures. The current research work develops and investigates the application of magnetic field and shielding gas in the electro-discharge deposition process with experimental work and simulation model. Response surface methodology model is developed to perform parametric analysis and to ascertain the significance of introducing magnetic field and shielding gas in an electro-discharge deposition process. Results from atomic force microscope and optical image microscope shows that at higher magnetic field the deposition height increases with reduced width. From the EDAX compositional analysis, it is noted that the presence of shielding gas increases the percentage of copper composition and reduces the carbon and oxygen composition in the deposited material. The obtained results confirmed that the presence of magnetic field and shielding gas significantly improves the deposition process.

“…It is proposed to apply a thin layer of solid grease on the surface of the workpiece to increase the discharge gap. Muralidharan et al [32] introduced permanent magnets and protected them by inert gas in the process of EDM deposition. The direction of magnetic field was perpendicular to the discharge channel.…”

An additive manufacturing (AM) method for the deposition of metallic layer in micron scale on monocrystalline silicon wafer surface by high voltage induced weak electric arc machining (HV-μEAM) has been proposed. The process characteristics of HV-μEAM are analyzed to fulfil the metal material deposition. The influence of the processing parameters on the deposition effect were studied with copper as additive electrode material. Using the optimal parameters, a number of complex trajectory deposition experiments have been carried out and a QD character-type deposition layer with a height of 139.09 μm has been obtained. The deposition has good continuity and high forming precision. It is proven that the new method is achievable and efficient for patterning metallic materials in the micro- and nano-scale on the silicon substrates surface.
