 This study examined the effects of electrolytic plasma processing on removing defective layers from damaged parts produced during electrical discharge machining, EDM. It found that applying plasma electrolytic polishing, PEP, after EDM improved the surface quality and mechanical properties of the parts. Additionally, the combination of EDM and PEP increased the fatigued life of the parts without failure up to 109 cycles. Further research is needed to ensure consistent removal of the unwanted defective layer.
