Duplex Surface Modification of 304-L SS Substrates by an Electron-Beam Treatment and Subsequent Deposition of Diamond-like Carbon Coatings

In this study, we present the results of effect duplex surface modification 304-L stainless steel substrates by an electron-beam treatment (EBT) and subsequent deposition diamond-like carbon coatings on roughness corrosion behavior. During EBT process, beam power was varied from 1000 to 1500 W. The successful DLC confirmed FTIR Raman spectroscopy experiments. showed a presence C–O, C=N, graphite-like sp2, mixed sp2-sp3 C–C bond vibrations. topography studied atomic force microscopy. rise in leads decrease deposited coatings. studies resistance samples have been performed using three electrochemical techniques: open circuit potential (OCP), cyclic voltammetry (polarization measurements), non-destructive impedance (EIS). measured potentials suggest that these are corrosion-resistant even medium, containing corrosive agents such as chloride ions. It can be concluded most specimen is coating electron-beam-treated SS substrate
