“…Atomic force microscopy (AFM) is an effective very‐high‐resolution tool in the investigation of surface structure (Méndez, Reyes, Trejo, Stępień, & Ţălu, ; Naseri et al, ; Sobola, Ţălu, Solaymani, & Grmela, ; Stach et al, ; Ţălu et al, ). Analysis of high resolution AFM images by image processing technique can reveal the specific distribution pattern and complexity of the 3‐D surface structures (Smagoń et al, ; Solaymani et al, ; Ţălu et al, ; Zavarian et al, ).…”

Introduction: In this study, a stereometric analysis of the three dimensional (3‐D) surfaces of the Ag/DLC nanocomposite synthesized by RF‐PECVD was performed. Materials and methods: Atomic force microscopy in noncontact mode was used to study surface morphology in correlation with multi‐parametric statistical analysis. The associated parameters of segmented motifs in conformity with ISO 25178‐2:, 2012 have been extracted using MountainsMap® Premium software. The mathematical algorithm computes detached watersheds of hill or dale motifs and determines the maximum and minimum points of motifs. Results and discussion: The stereometric analyses with MountainsMap® Premium software provided detailed information on the 3‐D surface topography of samples. Fractal analyses revealed the fractal nature of the performed samples is in correlation with the deposition time of samples. Detailed information of manufactured Ag/diamond‐like carbon (DLC) nanocomposite is given based on the information about the surface structure, properties, and performance characteristics. The performed analysis allows the high‐resolution modeling of Ag/DLC nanocomposite surface microtexture with motif analysis (intrinsic characteristics disclosure and characterization of surfaces fractal), in order to be included in computer interactive simulation algorithms. Conclusion: It was found the fractal dimension decreases with the increase of the deposition times on samples.

N + ions were incorporated into nickel-coated 316 stainless steel (SS) at room temperature using different energies (10, 20, and 50 keV) and a fluence of 5 × 10 17 N + cm −2. The microstructure, surface morphology, and corrosion inhibition of the obtained materials were investigated and compared with the properties of the untreated steel using several analytical techniques. The X-ray diffraction patterns indicated the formation of nickel nitride with the ion implantation process. The surface morphology of the samples was studied by atomic force microscopy and statistical and multifractal analytical methods. Moreover, the potentiodynamic polarization test in 3.5% NaCl solution was carried out to evaluate the corrosion properties of the samples. These studies revealed that the generalized fractal dimension, Dq, is dependent on the ion implantation energy and the symmetry of the multifractal singularity spectra, f (α), which is related to the uniformity of the sample. In this manner, the lowest value was obtained for the sample prepared with the maximum ion implantation energy. Also, the increment of the implantation energy yields to increase the corrosion resistance. The simultaneous decrease of the corrosion current density (Icorr) and the increase of the corrosion potential observed with the N + ion-implantation indicate that treated samples are more resistant to corrosion than the untreated steel, and the highest corrosion protection was observed for the maximum implantation energy (50 keV). The correlation between corrosion resistance, structural and surface morphology induced by implantation is discussed.

“…Particularly exceptionally are silver thin films. Silver is one of the highest electrically conductive (6.3 × 10 7 S/m) materials among all the metals; thus, 2D Ag thin films can be excellent candidates in flexible electronics [15,16]. On the other hand, nanostructured Ag thin films show improved plasmonic [17,18], electrical and antimicrobial properties with exceptional uses as surface enhanced Raman scattering (SERS) active substrates [19], components for microelectronics and microelectromechanical systems [20] and antibacterial coatings [21].…”

“…In recent years, different methodologies have been proposed to synthesize silver thin films and 2D assemblies of nanoparticles and nanowires. One of the main goals of these production methods is to control the structure of nanomaterials to obtain unique structures with engineered properties, exploring the dependence of their properties on the parameters of synthesis using different analytical and imaging techniques [16,[22][23][24]. Among Fractals are infinitely complex patterns that are self-similar across different scales.…”

Nowadays, there is a great interest in designing and fabricating thin films with unique morphologies to improve the surface properties for various applications. In this regard, atomic force microscopy (AFM) is widely used to investigate the surface morphology of thin films. The high spatial and vertical resolution makes AFM capable of extracting surface micro-roughness information precisely. In this study, Ag-DLC films were deposited on different substrates using the RF-PECVD method. The morphological properties were studied by AFM analysis according to ISO 25178-2: 2012.The results of analyzing the AFM data demonstrate that a copper substrate is a good option for the fabricated silver film in this study, and it is a relatively ideal surface in terms of fractality.
