“…The corrosion current values can be determined from cathodic tangent slope and corrosion potential. 54 Corrosion rates of copper-coated PPCs in a year were calculated as illustrated in Table 8 and 9. The testing results in 1 M methanol solution demonstrated that copper-coated PPC 3 had the lowest E corr and the highest I corr corrosion rate as shown in Table 8.…”

“…In the course of exploitation, the defects inherent in condensed multicomponent ion-plasma coatings (presence of a micro drop fraction in plasma that leads to low local adhesion even after high-temperature diffusion annealing; no uniformity of phase components distribution over surface and depth; high roughness of coating) may lead to reduction of heat resistance of coating and its resistance to SOC. Some measures are needed for their leveling (Kahraman et al, 2016;Sentry et al, 2018). Therefore,it is expedient to modify surface layers of condensed ion-plasma coatings using a highcurrent pulsed electron beam (HPEB) ( The objective of the present work is an investigation of the effect of modifying coating surface layers on resistance to SOC by using HPEB condensed ion-plasma NiCrAlY coatings.…”

Recently, the emergence of accelerators of high-current electron beams and powerful electron ion beams has contributed to the creation of unique effects of concentrated energy flows on materials. Upgrading of production processes and development of new technological processes of both domestic aircraft propulsion engineering and aviation arms remain topical and needed. Engine operational reliability depends on that of turbine blades. They are the most loaded details because they are experienced to action of static, dynamic and cyclic loadings as well as are subjected to cyclic thermal stresses. Therefore the main objective of our paper is to analyze the effect of high-current electron beam irradiation on-resistance of sulfide-oxide corrosion (SOC)of Ni-Cr-Al-Yion-plasma coatings. To achieve this purpose, beam irradiation was performed using the RITM-SP complex automated electron-beam setup. Modification of surface layer of SDP 2+VSDP16 ion-plasma coating by microsecond high-current electron beams of selected mode made it possible to increase considerably the SOC resistance. An analysis of the surface and microstructure of samples after SOC testing enabled to determine different effects of medium on sample coating depending on the state of the sample surface. When investigated samples microstructure, we found that after modification certain cracks on sample surface did not develop in the course of testing. It was found that some craters were not necessarily centers of corrosion damage origin, i.e., the existence of given types of craters and their impact on SOC resistance stability are ambiguous.

“…The TiN coating is one of the first PVD-deposited nitride coatings. This coating is still actively used in various fields, including increasing the corrosion resistance of products made from titanium alloys and steels of various compositions [21][22][23][24][25][26][27][28][29][30]. It had been reported in the literature that the TiN coatings did not provide complete corrosion protection [21,31,32] and that they only experienced slight corrosion along the grain boundaries of the TiN coatings when they were exposed at a temperature of 500 • C onto the NaCl crystals [31].…”

In this work, the mechanical properties and corrosion resistance of Cr-CrN, Ti-TiN, Zr-ZrN, and Mo-MoN coatings deposited by the physical vapor deposition (PVD) method on Ti-6Al-4V alloy were compared. The phase composition of the coatings, their hardness and fracture resistance in scratch tests were determined, and their structural characteristics were also studied using a scanning electron microscope (SEM) and a transmission electron microscope (TEM). The diffraction spectra were made using an automatic X-ray diffractometer. The value of the adhesive component of the friction coefficient fadh of the pair “coated and uncoated Ti-6Al-4V alloy” was investigated in the temperature range of 20–900 °C. The lowest value of fadh was detected for the Zr-ZrN coating at temperatures below 400 °C, while for the Mo-MoN coating it was observed at temperatures above 700 °C. The polarization curves of the coated and uncoated samples were performed in a 3% aqueous NaCl solution. The level of corrosion of the Ti-6Al-4V alloy samples with Cr-CrN, Ti-TiN, Zr-ZrN, and Mo-MoN coatings was evaluated using the Tafel extrapolation method, the iteration method, and the polarization resistance method. The results obtained with these methods indicate that the Zr-ZrN coated sample has the best corrosion resistance in the 3 wt.% NaCl solution, with a corrosion current density of 0.123 μA/cm2.
