“…CrN/CrCN coating produced at the C 2 H 2 flow rate of 30 sccm had lower CoF (0.63) than CrN coating (0.69), but higher wear: the width of the wear track was 180.9 µm and 171.5 µm, respectively. Better wear resistance of the multilayer coating compared to the monolayer have been obtained testing CrN and DLC coatings with or without Fe 3 Al-based interlayer [139]. Similar results of wear resistance of the multilayer coatings have been also obtained in References [13,140,141].…”

Due to the increasing maintenance costs of hydraulic machines related to the damages caused by cavitation erosion and/or erosion of solid particles, as well as in tribological connections, surface protection of these components is very important. Up to now, numerous investigations of resistance of coatings, mainly nitride coatings, such as CrN, TiN, TiCN, (Ti,Cr)N coatings and multilayer TiN/Ti, ZrN/CrN and TN/(Ti,Al)N coatings, produced by physical vapor deposition (PVD) method using different techniques of deposition, such as magnetron sputtering, arc evaporation or ion plating, to cavitation erosion, solid particle erosion and wear have been made. The results of these investigations, degradation processes and main test devices used are presented in this paper. An effect of deposition of mono- and multi-layer PVD coatings on duration of incubation period, cumulative weight loss and erosion rate, as well as on wear rate and coefficient of friction in tribological tests is discussed. It is shown that PVD coating does not always provide extended incubation time and/or improved resistance to mentioned types of damage. The influence of structure, hardness, residence to plastic deformation and stresses in the coatings on erosion and wear resistance is discussed. In the case of cavitation erosion and solid particle erosion, a limit value of the ratio of hardness (H) to Young’s modulus (E) exists at which the best resistance is gained. In the case of tribological tests, the higher the H/E ratio and the lower the coefficient of friction, the lower the wear rate, but there are also many exceptions.

“…The best wear resistance was achieved by the coating with the highest H/E ratio. Additionally, in References [129,139], there was shown that the higher the resistance to plastic deformation, the lower the wear rate. However, not all investigations confirm this relationship.…”

“…In recent years, numerous articles have reported the use of non-thermal plasmas at atmospheric pressure to convert complex molecules into fragments for deposition purposes. The variety of results sought range from the creation of hydrophobic/ hydrophilic surfaces for biocompatible or anti-fog materials [1][2][3][4] to ultra-hard, wear-resistant layers for the semiconductor and aeronautic industries [5][6][7]. Other applications of non-thermal plasmas at atmospheric pressure include the production of nanostructures using organosilicon and organotitanium precursors [8], the abatement of harmful greenhouse effect gases such as perfluorinated compounds [9], the conversion of CO 2 molecules into valued products [10][11][12] or the generation of reactive neutral species for plasma medicine [13,14].…”

A combination of optical emission and absorption spectroscopy of argon 2p –1s transitions (Paschen notation) combined with collisional-radiative (CR) modelling of argon 2p states was used to characterize microwave argon plasmas at atmospheric pressure in presence of N2, O2, and H2 admixtures. In particular, the neutral gas temperature (obtained from the broadening of argon 2p 2–1s2 and 2p 3–1s2 emission lines), the number density of argon 1s5 atoms (obtained from absorption spectroscopy of the argon 2p 9–1s5 transition using a tunable laser diode), the electron temperature (obtained from the comparison between measured and simulated argon 2p -to-1s relative line emission intensities), and the electron density (obtained from the Stark broadening of the Hβ line and argon relative line emission intensities) were recorded as a function of the axial distance along the microwave plasma column. The results show that, for a given position in the plasma and a higher amount of admixture in the nominally pure argon plasma, the neutral gas temperature increases and the electron number density decreases, while the electron temperature and the population of argon metastable atoms first decreases and then increases at higher concentrations. With such information, a detailed analysis of the electron power balance was performed. It is found that less than 1% of the admixture in the argon plasma already absorbed more than 80% of the microwave power. Part of this energy is used for neutral gas heating, mostly through electron-impact excitation of rotational levels.

“…The tests involved loading samples of SS and PEEK against 10 mm diameter alumina balls, as shown in Figure 2 . Similar to other studies [ 22 , 23 , 24 ], alumina was selected as the counterpart material due to its increased and improved mechanical and chemical inertness qualities. The samples cemented to zirconia were carefully mounted on a 3D-printed PLA holder attached to the specimen support.…”

Tribological Behavior of TiO2 PEEK Composite and Stainless Steel for Pediatric Crowns

Dental decay still presents a major health problem among children. Its treatment usually requires the use of stainless steel crowns. This study compares the wear behavior of 316 L stainless steel and polyetheretherketone (PEEK) composite under identical test conditions. The wear tests were conducted in a reciprocating ball-on-plate tribometer (Plint TE67/R) using alumina balls as a counterface and artificial saliva as a lubricant at 37 °C to faithfully mimic oral conditions. The coefficient of friction (COF) and specific wear rate (k) values were determined and SEM/EDS examinations were performed to identify the predominant wear mechanisms. Results showed that PEEK exhibited a significantly lower coefficient of friction (COF = 0.094 ± 0.004) and thus lower wear volume (ΔV = 0.0078 ± 0.0125 mm3) and higher wear resistance, with an average value of specific wear rate of k = 9.07 × 10−6 mm3N−1m−1 when compared to stainless steel (COF = 0.32 ± 0.03, ΔV = 0.0125 ± 0.0029 mm3, k = 1.45 × 10−5 mm3N−1m−1). PEEK was revealed to be a potential material for use in pediatric crowns due to its high wear resistance while overcoming the disadvantages associated with steel at both an aesthetic and biological level.
