“…Chakraborty S et al [27] discussed a parametric optimization using Taguchi analysis, and observed that the peak current, electrode compaction load, and electrode composition are the major influencing parameters on material transfer rate and surface roughness. Maddu J et al [28] made a review on different parametric optimization techniques for EDC process.…”

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.

“…Solidification of the molten slurry is carried out at high squeezing pressures, which enhance the microstructure and mechanical properties [17,18]. In the fabrication of Al MMCs, many types of aluminum alloys have been adopted, e.g., Al6061 [19], AA2124 [20], Al7039 [21], Al7075 [22], Al A359 [23], Al A356 [24], Al6351 [25], and Al2124 [26], as matrix materials.…”

Among the various types of metal matrix composites, SiC particle-reinforced aluminum matrix composites (SiC p /Al) are finding increasing applications in many industrial fields such as aerospace, automotive, and electronics. However, SiC p /Al composites are considered as difficult-to-cut materials due to the hard ceramic reinforcement, which causes severe machinability degradation by increasing cutting tool wear, cutting force, etc. To improve the machinability of SiC p /Al composites, many techniques including conventional and nonconventional machining processes have been employed. The purpose of this study is to evaluate the machining performance of SiC p /Al composites using conventional machining, i.e., turning, milling, drilling, and grinding, and using nonconventional machining, namely electrical discharge machining (EDM), powder mixed EDM, wire EDM, electrochemical machining, and newly developed high-efficiency machining technologies, e.g., blasting erosion arc machining. This research not only presents an overview of the machining aspects of SiC p /Al composites using various processing technologies but also establishes optimization parameters as reference of industry applications.

“…The I p influenced the MDR and Ra the most. Chakraborty et al 2 conducted research on the impact of electro-discharge coating (EDC) process parameters on Al-6351 with a PM tool of SiC/Cu. Their findings revealed that the T on had the greatest influence, resulting in high microhardness (MH) and low Ra.…”

Utilising electro-discharge machining, powdered metallurgical tool materials are applied to coat the surface pattern-wise. The tool undergoes a thorough blending process followed by hydraulic pellet press. Essential evaluations encompass the determination of material deposition rate, tool wear rate, surface roughness, microhardness, layer thickness and wear rate. Characterisations confirm the presence of tool constituents, provide insights into its constituent's composition and reveal the formation of tungsten carbides on the uppermost surface of the deposit. Significantly, a substantially higher deposition rate of 4.9 mg/min is achieved when a compact load of 10 tons and a peak current of 2.5A are applied. Notably, the top surface exhibits a microhardness of 330.5 HV, while the base material maintains a hardness level of 98.7 HV. The maximum thickness of the deposited layer reaches 293.68 μm under identical conditions. These hard materials serve to mitigate the specific wear rate effectively.
