The present paper studies the material removal evolution, during Plasma Electrolytic Polishing (PeP), on model roughnesses prepared 1050 aluminum alloy (AA), i.e. a quasi-pure aluminum, used as substrate. results obtained in this study confirm significance of applied voltage removal. In particular, minimal to be generate plasma is seen above 230 V. Meanwhile, at higher 300 V, high quality polis...

INTRODUCTION: Titanium and titanium alloys have attracted considerable interest in aerospace, chemical process and biomedical industry due to their biocompatibility, good mechanical properties and excellent corrosion resistance. The chemical stability of titanium results from the presence of a thin but stable surface oxide film, typically a few nanometer thick. In nonaqueous electrolytes contai...
