“…At the high wavenumber region (Figure 3), four peaks appeared at wavelengths of 2750 cm −1 , 2848 cm −1 , 2917 cm −1 , and 2953 cm −1 , respectively. The band at 2750 cm −1 indicates the presence of ethyl group [32] and the other peaks correspond to sp 3 -CH 3 configuration [33], sp 3 -CH 2 (asymmetrical) [34], and sp 3 -CH 3 (asymmetrical) bonds [35]. The asymmetrical vibration sp 3 -CH 2 is due to the sp 3 -hybridized carbon to hydrogen and tetrahedral carbon structure [36], and is the highest absorption band at 1000 W. Additionally, it has been reported as a result of hydrogen bonds in the form of sp 3 -CH 2 and sp 3 CH 3 groups [37].…”

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

“…Nevertheless, on the EDS spectrum shown in Fig. 5 (b), the formation of polymers was discounted due to the absence of hydrogen, which is expected from polymers due to H-C bonds [6]. A randomly chosen initial sample thought to be Al was used.…”

In this study, we present the development and characterization of a homegrown magnetron sputtering system (MSS) constructed from repurposed materials. Borosilicate glass slides were used as the substrate material, while Al, Fe, and Cu were employed as target materials. The system was validated, optimized, and successfully utilized for the deposition of Cu, Al, and Fe films onto the glass substrate. The resulting samples were analyzed for their structure, morphology, photoluminescence, and electrical conductivity using XRD, EDS, SEM, and the 4-point probe method. Our findings indicate that the MSS produces results that compare favorably with standard sputtering equipment, but with significant potential for further refinement. Overall, our work highlights the feasibility and versatility of utilizing homegrown sputtering systems for a range of research applications.
