“…It should be mentioned that such behavior was reported in numerous studies for both hydrogen-free and hydrogenated DLC films containing silicon or SiO x [8,[33][34][35][36]. G peak position downshift to 1505 cm −1 [21], 1495 cm −1 [23], 1480 cm −1 [12] and even as low as 1460 cm −1 [17,19] was reported. In those studies, the changes were explained by the increased sp 3 /sp 2 carbon bond ratio.…”

“…Silicon doping of DLC films resulted in reduced internal stress, increased hardness, and improved high-temperature tribological properties [15]. Reduced internal stress and friction coefficient of DLC:Si films as compared with undoped DLC films are presented in [16,19]. It was shown that friction coefficient of DLC:Si films in ambient air was lower than the friction coefficient of the…”

“…Properties of DLC films can be additionally controlled by introducing chemical elements other than carbon or hydrogen [1,[3][4][5][6][7][8]. Particularly, silicon is one of the most often used DLC dopants [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Reduced internal stress and friction coefficient, as well as increased thermal resistance, while keeping high hardness of Si doped diamond-like carbon films were reported [9].…”

In the present research diamond-like carbon (DLC) films containing 4–29 at.% of silicon were deposited by reactive magnetron sputtering of carbon target. Study by X-ray photoelectron spectroscopy revealed the presence of Si–C bonds in the films. Nevertheless, a significant amount of Si–O–C and Si–Ox bonds was present too. The shape of the Raman scattering spectra of all studied diamond-like carbon containing silicon (DLC:Si) films was typical for diamond-like carbon. However, some peculiarities related to silicon doping were found. Studies on the dependence of DLC:Si of the optical transmittance spectra on the Si atomic concentration have shown that doping by silicon affects linear, as well as nonlinear, optical properties of the films. It is shown that the normalized reflectance of DLC:Si films decreased with the increased exciting light fluence. No clear relation between the normalized reflectance and photoexcited charge carrier relaxation time was found. It was suggested that that the normalized reflectance decrease with fluence can be related to nonlinear optical properties of the hydrogenated diamond-like carbon phase in DLC:Si film.

“…3e shows that the Si 2p spectra exhibit three different peaks at binding energies of 100.8 eV, 102.045 eV, and 103.0 eV, which were assigned to Si-C, Si-O-Al, and Si-O-C bonds, respectively. 24 These results confirm that PFDS was grafted onto the anodic Al 2 O 3 surface and are strong evidence of the super hydrophobicity of the aluminum substrate.…”

“…The C 1s spectra ( Fig. 3c) exhibit six different peaks at the binding energies of 294.1 ev, 291.6 ev, 289.6 ev, 288.8 ev, 285.5 ev, 283.8 ev, which were respectively assigned to the bonds [22][23][24] the -CF 3 , -CF 2 , -CH 2 -CF 2 came from PFDS. Owing to the low surface energy -CF 3 and -CF 2 components, the anodic Al 2 O 3 layer modified with PFDS is strongly water repellent, as also confirmed in later experiments (CA).…”

Material corrosion induced by temperature variations is one of the main threats to materials immersed in complex and changeable marine environments. Superhydrophobic surfaces (SHS) are promising for protecting the underlying metal from corrosion. However, temperature variations in underwater environments have hindered the practical application of SHS, thus, their corrosion protection ability is limited. However, slippery liquid infused porous surfaces (SLIPS) can compensate for the aforementioned defects of SHS. In this research, a kind of SLIPS was designed over aluminum for marine corrosion applications using a three-step procedure, consisting of anodization, fluorination and solvent exchange method. The as-prepared SHS and SLIPS were characterized with scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and wettability measurement, and their corrosion properties were investigated by electrochemical impedance spectroscopy (EIS). With the perfluorinated lubricant and aluminium oxide coating, the SLIPS presented high corrosion resistance (2.06 × 10 9 Ω cm 2) in a broad temperature range.
