“…Topographic images obtained by the AFM technique can provide several stereometric parameters that, recently, have been used to study many fabricated physical systems, mainly thin films, for example, (Dallaeva et al, 2012; Ito et al, 2020; Rezaee et al, 2020) or biological, such as biofilms (Matos et al, 2020), leaves (Ramos, Matos, & da Fonseca Filho, 2020), insect structures (Zaneta, Sebastian, Ştefan, Dinara, & Zygmunt, 2017), and teeth (Nezafat et al, 2019). Based on the information generated by these parameters, various aspects of the physical properties of the surface such as flatness, roughness, shape of rough peaks, texture symmetry, density, and texture direction can be better understood.…”

Dinizia excelsa Ducke under three different cut conditions were carefully analyzed. The morphology and stereometry of different wood cutting surfaces (longitudinal radial, longitudinal tangential, and transversal) were studied by SEM and AFM. The results obtained in this study suggest that both the height parameters and the advanced stereometric parameters of the surfaces did not reveal a significant difference, indicating that the spatial patterns do not change according to the type of cut. In this way, the surface microtexture does not vary depending on the cut type. Similarly, the Hurst's coefficients did not show any significant difference in the spectrum of the PSD fractal region. On the other hand, Minkowski functionals presented a morphological difference between the samples. These results showed that the microtexture of the wood surface does not change as a function of the type of cut submitted to the same polishing process.

“…Transition-metal nitride coatings have high hardness, good chemical inertness and high resistance to wear and corrosion. These characteristics make them promising candidates for resisting severe tribocorrosion in marine environments [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The binary chromium nitride (CrN) coatings were developed in order to enhance resistance to wear and corrosion in high speed rotating parts; however, these coatings showed unsatisfactory service life in industrial applications [13].…”

Transition-metal nitride coating used to protect the electronic connector devices in marine environment is required to have high electrical conductivity and good corrosion resistance. This study synthesized a novel CrN–Pt coating with a dense growth texture. Pt addition induced a pronounced increase in electrical conductivity and corrosion resistance. The resistivity decreased from 0.0149 Ohm·cm in the CrN coating to 0.000472 Ohm·cm in the CrN–Pt coating, while the corrosion current density decreased from 24 nA/cm2 in the CrN coating to 6.3 nA/cm2 in the CrN–Pt coating. The results of the above studies confirm that Pt doping has significant advantages in improving the electrical conductivity and corrosion resistance of nitride coatings for potential applications in the marine environment.

“…One of these influences is corrosion, a destructive process that destroys the metallic structure and causes material failures and structural damage. Special attention is thereby paid to the corrosion behavior of stainless steels [1]. Numerous marine structures and fittings are most often made of stainless steel, because of its comparably good corrosion resistance in sea water, while having high strength and Young's modulus much higher than aluminum alloys.…”

In this work, a single-layer TiO2–ZrO2 thin film is deposited on the AISI 316L austenitic stainless steel by the sol–gel process and the dip coating method to improve its corrosion resistance properties. For the sol preparation, titanium isopropoxide and zirconium butoxide are used as the precursors, yttrium acetate hydrate is used for the ZrO2 stabilization, i-propanol as the solvent, nitric acid as the catalyst, acetylacetone as the chelating agent, and the distilled water for the hydrolysis. The deposited films are annealed at 400 °C or 600 °C. Morphology and phase composition of the sol–gel TiO2–ZrO2 films and powders are analyzed by scanning electron microscopy (SEM) equipped with EDX detector and X-ray diffraction (XRD), respectively. The thickness of the sol–gel TiO2–ZrO2 films deposited on the stainless steel is determined by glow discharge optical emission spectrometry (GD-OES). The corrosion behavior of the stainless steel, coated by amorphous films, is evaluated in 3 wt% NaCl and 0.5 mol dm−3 HCl by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. It is found that the sol–gel TiO2–ZrO2 films with the amorphous structure, deposited by the sol–gel process, and calcined at 400 °C significantly enhance the corrosion properties of AISI 316L in both chloride media.
