Sažetak
In the paper, a novel process named the High-Voltage Electropolishing (HVEP) is proposed to gain the specific surface properties on the treated metallic material. The AISI 304L stainless steel as the biomaterial was used for the HVEP treatment. Another feature of this work is using a concentrated phosphoric acid solution within the copper nitrate as electrolyte. The main purpose of the HVEP processing in that kind of electrolyte was to incorporate the copper ions into the passive surface film. Such a modified surface nanolayer was studied by means of the X-ray Photoelectron Spectroscopy (XPS) to reveal the composition of the obtained film. The comparison of the numerical results, dependent on the voltage applied, was performed. Moreover, the Cr/Fe and Cu/P ratios were determined to show the advantages of this electrochemical HVEP treatment.
