Abstract
Electro Discharge Coating (EDC) has emerged as a significant
advancement in surface engineering, particularly in applications demanding
enhanced surface properties such as wear resistance, corrosion resistance, and
thermal stability. The technique leverages the principles of Electro Discharge
Machining (EDM) while integrating material deposition capabilities, enabling
simultaneous machining and surface enhancement. This review investigates the
mechanisms, process parameters, material selection, and technological
developments surrounding EDC. A detailed comparison of coating thickness and
wear resistance between EDC and conventional methods such as electroplating and
thermal spraying is provided. Furthermore, recent developments in powder
metallurgy, pulse current optimization, and hybrid processes are examined.
Updated references and graphical data illustrate the progression and potential
of EDC as a future-forward coating solution in industrial manufacturing.
