“…And reports composition layer mainly constituents of W, Cu, and their carbides, coat layer formation depends on the composition of powder metallurgical electrodes, compaction load, and machining parameters such as current, pulse on time, and voltage. Tyagi R et al [100] investigate EDC process using a mixture of copper and brass powder green compact electrode on mild steel substrate, and reports that a coated layer consists of Cu, CuZn, and Fe. Arun I et al [101] explain the influence of silicon powder on PMEDC process on stainless steel, silicate layer formed improved the wear resistance of the substrate.…”

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.

“…Besides, the mixture of two or more powders has a significant effect on the rate of material deposition and tool wear [117]. A binding powder is added in the green compact to improve the efficiency of the EDC process [122]. This binding powder material provides strength to the green compact and also helps in enhancing its conductivity when the other powder is less conductive [123].…”

Electrical discharge coating (EDC) process is used to deposit material on workpiece surface from sacrificial or green compact tool electrode in an electrical discharge machine. The paper presents the mechanism of EDC using green compact electrode and powder mixed dielectric methods. The tool electrode material, electrode size, process parameters, and type of dielectrics can directly affect the surface integrity of workpiece. Here, a process map of EDC as a function of process parameters, its classification, advantages, and applications for a wide range of engineering materials offers a proper template for the evaluation of coating phenomena. This study shows that EDC is an economic process as compared to other costlier techniques. Additionally, the effect of various EDM and EDC parameters on surface integrity and tribological behavior of deposited coatings is studied with their pros and cons. Finally, the current research trends of EDC and its challenges are elaborated.
