What is it about?
Electrical discharge coating (EDC) is an emerging surface modification technology to produce such hard coatings by using electrical discharges to coat a layer of material on workpiece surface to modify and enhance the surface characteristics or create new surface functions. This paper presents a comprehensive overview of EDC technologies for various materials, and summarizes the types and key parameters of EDC processes as well as the characteristics of resulting coatings.

Why is it important?
The findings show that the powder mixed electrical discharge machining and powder metallurgy electrode methods are effective solutions for realizing EDC and this process brings many advantages in enhancing the surface properties and creating surface functions of metal and other materials.
Perspectives
This paper offers a comprehensive overview of the essential principles and prominent aspects within electrical discharge coating process, along with insights into its applications and prospective developments. We anticipate that this will prove valuable to individuals engaged in the realm of surface modification.
