Considerations about obtaining some different distinct qualities of protection layer of metallic surfaces by covering in different electric fields

This article describes some of the characteristics of charged particles in a constant electric field. For static electrical fields, when the voltage in the powder layer exceeds the value of the dielectric rigidity, a back-corona phenomenon takes place, leading to the appearance of "craters" on the surface that represents the protection layer. This is the core of our research in this domain, with a focus on the use of some variable of the electric field.
