“…Erdemir [ 40 ] indicate that highly hydrogenated carbon coatings during a tribological test performed in the open air absorbed more oxygen species and water molecules than other surfaces. Therefore, one of the reasons for the occurrence of better microtribological performance obtained by the lower coefficient of friction for Si-DLC coating (0.214 ± 0.011) compared to DLC coating (0.240 ± 0.011) is linked with the presence of native silicon forms (SiO x ) [ 50 ]. Silicon oxides in combination with the presence of water in the form of water meniscuses enhance the formation of a Si(OH) 4 layer at the top of the investigated surfaces according to the following reaction:

The presented article shows the influence of concentration of perfluoroalkylsilanes in solutions on tribological properties of self-assembled monolayers (SAMs) deposited on three surfaces with different silicon content in the millinewton load range. The SAMs were created using the liquid phase deposition (LPD) method with 1H, 1H, 2H, 2H-perfluorodecyltrichlorosilane (FDTS) and (3, 3, 3-trifluoropropyl) trichlorosilane (FPTS) solutions, for which viscosity and surface tension were estimated. Deposited layers were analyzed in terms of thickness, coverage, wettability, structure and coefficient of friction. The obtained results demonstrated that SAMs created on the silicon-incorporated diamond-like carbon (Si-DLC) coatings possess the best microtribological properties. Systems composed of perfluoroalkylsilane SAM structures deposited on Si-DLC coatings are highly promising candidates as material for microelectromechanical applications.

“…[9] Thus, good adhesion of a-C:H:SiO x films deposited by plasma-assisted chemical vapor deposition (PACVD) is provided to a wide range of substrates, while maintaining excellent physical, mechanical, and tribological properties typical to DLC. [10] The biological performance of a-C:H:SiO x films was studied in several publications. [11][12][13] Randeniya et al [11] studied the effect from Si and SiO x incorporated into the DLC films on osteoblast adhesion.…”

“…SiO x -doped DLC films have relatively high hardness (10-20 GPa), [14] low friction coefficient (0.02-0.2), [9,10] and low wear rate (~10 −7 mm 3 /NÁm). [10,15] To the best of the authors' knowledge, no publications can, however, be found in the literature that address the issue of the a-C:H:SiO x film deposition on PP medical devices, which require sterilization. Sterilization must not cause noticeable changes in the properties, structure, and composition of the biocompatible barrier coating and polymer substrate.…”

Polypropylene (PP) is traditionally used in the production of medical devices, such as catheters, dialyzers, syringes due to its good chemical and thermal resistance, biocompatibility, and low cost. Sterilization can however damage these devices, when the polymer additive releases into physiological fluids, thereby harming the patient health. This article proposes to deposit biocompatible a‐C:H:SiOx coatings onto PP surfaces and studies the coating stability after chemical sterilization. Five different chemical sterilizers, namely, hydrogen peroxide, ethanol, miramistin, formaldehyde, and ethylene oxide are used to compare their effect on the coating stability on the PP substrate. Untreated and sterilized samples are incubated in a liquid synthetic nutrient to obtain extracts that are used for sterility testing and determining the degree of interaction of samples with the nutrient medium. The changes in the coating functional groups and surface morphology are examined by using the Fourier transform infrared spectroscopy and the scanning electron microscopy, respectively. It is shown that the a‐C:H:SiOx coating has a protective effect on the PP substrates subjected to chemical sterilization. The experiment results clearly showed that the ethanol sterilization causes the most serious changes in the structure of PP, and also leads to the barrier coating failure. On the other hand, ethylene oxide sterilization has a minimal effect on the structure of both uncoated and coated PP substrates.

“…To eliminate these negative effects, numerous coating technologies, ion implantation techniques, shot peening, or thermal oxidation techniques can be used. These processes enable changing the nature of the surface via modification of the top layer of a titanium alloy and, at the same time, improving their mechanical, chemical, biological, and tribological properties [ 7 , 11 , 12 , 13 , 14 , 15 ].…”

Comparison of the Physicochemical Properties of Carboxylic and Phosphonic Acid Self-Assembled Monolayers Created on a Ti-6Al-4V Substrate

This study compared the tribological properties in nano- and millinewton load ranges of Ti‑6Al-4V surfaces that were modified using self-assembled monolayers (SAMs) of carboxylic and phosphonic acids. The effectiveness of the creation of SAMs with the use of the liquid phase deposition (LPD) technique was monitored by the contact angle measurement, the surface free energy (SFE) calculation, X-ray photoelectron spectroscopy (XPS), and Fourier-transform infrared spectroscopy (FTIR) measurements. The obtained results indicated that more stable and well-ordered layers, which were characterized by the lowest values of the coefficient of friction, adhesion, and wear rate, were obtained using phosphonic acid as a surface modifier. Based on the obtained results, it was found that the Ti-6Al-4V alloy modified by phosphonic acid would be the most advantageous for practical applications, especially in micro- and nanoelectromechanical systems (MEMS/NEMS).
