Influence of Gaseous Dielectric Environments on Dry Electro Discharge Coating of Al 6061 Alloy with Zirconia–Copper Electrodes

Key Points

• Dry electro discharge coating resulted in improved adhesion under specific gaseous dielectric conditions, highlighting environment’s role.
• Notably, experiments indicated an increase in coating quality when applying zirconia-copper electrodes in gaseous dielectric settings.
• Analysis across various environments showed variations in coating morphology and surface characteristics based on the dielectric type.
• Future studies should investigate long-term durability of coatings produced in these environments and their applications.
