Electrolytic plasma process (EPP) was used as a fast annealing treatment on ball milled surfaces. With localized melting of EPP, the surface morphology and the chemical composition can be drastically changed. Annealed, ball milled and EPP treated stainless steel 304 samples were examined and EPP treatment has been shown to improve the overall corrosion and localized corrosion. Materials were characterized by X-Ray Diffraction, SEM. The 24 hours of exposure in NaCl solution, the sample open-circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy were measured to estimate the anti corrosion properties.
