“…The tribological test of TiAlN, TiAlSiN, CrN/TiAlCrSiN and CrN/CrCN/DLC coatings showed that no correlation between H/E or H 3 /E 2 ratio and the wear resistance [148]. Similarly, the tests of TiAlN(Ag,Cu) and AlNiTiSiB(N) coatings did not confirm this relationship [135,149]. Lack of such correlation was also noted in Ref [134].…”

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.

d Zr targets. The synthesis of the coatings was carried out by varying the discharge power in the Ti5 well as a variation in the deposit temperature at room temperature 130° and 260°C. The coatings were characterized by means of X-ray diffraction (XRD), evidencing the formation of the phase that belongs to the solid solution (Zr, Ti)N, scanning electron microscopy (SEM), UV-Vis spectroscopy and hardness and pin-on-disc tests. The thickness was measured through interferometry with values between 662 and 481nm for the deposited coatings. According to the failure mechanism in the scratch test, the best results were obtained with a power of 170W and 260°C with a cohesive failure Lc1 = 2.1N and an adhesive failure Lc2 = 4.7N.

“…ZrB 2 -based coatings can be produced by a wide variety of techniques, including plasma deposition [21][22][23], diffusion saturation [24], salt electrolysis [25], electrospark deposition [26,27], chemical vapor deposition [28] and arc-PVD [29]. Magnetron sputtering offers several advantages, including low surface roughness, substrate geometry retention [30,31], low content of pores and structural defects [32,33], high adhesion to the substrate when the preliminary ion etching is applied [34][35][36], precise control of the structural characteristics via the adjustment of the sputtering parameters [37], the versatility of the used substrates [38][39][40][41] and uniform depth-wise distribution of the elements in the multi-element coatings [41][42][43].…”

The coatings ZrB2 and Zr-B-N were deposited by magnetron sputtering of ZrB2 target in Ar and Ar–15%N2 atmospheres. The structure and properties of the coatings were investigated via scanning and transmission electron microscopy, energy dispersion analysis, optical profilometry, glowing discharge optical emission spectroscopy and X-ray diffraction analysis. Mechanical and tribological properties of the coatings were investigated using nanoindentation, “pin-on-disc” tribological testing and “ball-on-plate” impact testing. Free corrosion potential and corrosion current density were measured by electrochemical testing in 1N H2SO4 and 3.5%NaCl solutions. The oxidation resistance of the coatings was investigated in the 600–800 °С temperature interval. The coatings deposited in Ar contained 4–11 nm grains of the h-ZrB2 phase along with free boron. Nitrogen-containing coatings consisted of finer crystals (1–4 nm) of h-ZrB2, separated by interlayers of amorphous a-BN. Both types of coatings featured hardness of 22–23 GPa; however, the introduction of nitrogen decreased the coating’s elastic modulus from 342 to 266 GPa and increased the elastic recovery from 62 to 72%, which enhanced the wear resistance of the coatings. N-doped coatings demonstrated a relatively low friction coefficient of 0.4 and a specific wear rate of ~1.3 × 10−6 mm3N−1m−1. Electrochemical investigations revealed that the introduction of nitrogen into the coatings resulted in the decrease of corrosion current density in 3.5% NaCl and 1N H2SO4 solution up to 3.5 and 5 times, correspondingly. The superior corrosion resistance of Zr-В-N coatings was related to the finer grains size and increased volume of the BN phase. The samples ZrB2 and Zr-B-N resisted oxidation at 600 °C. N-free coatings resisted oxidation (up to 800 °С) and the diffusion of metallic elements from the substrate better. In contrast, Zr-B-N coatings experienced total oxidation and formed loose oxide layers, which could be easily removed from the substrate.
