“…Alloying elements included in the nickel sublayer should modify the coating, and the sublayer becomes an obstacle to the dissolution of refractory alloy elements in the diffusion coating layer. In some cases, thin (~ 3-5 μm) anti-diffusion barrier layers of metal carbides are used, made, for example, by highenergy plasma chemistry (Muboyadzhyan et al, 2010;Muboyadzhyan, 2010;Muboyadzhyan, 2011;Kablov et al, 2007). It was mentioned that condensation-diffusion coatings have significantly higher protective properties compared to conventional condensed coatings.…”

“…Another step forward was the original high-energy ionplasma technology developed at FSUE "VIAM" and the creation of ion-plasma systems MAP-1M, MAP-2, MAP-3. A significant amount of developed thin-layer ion-plasma diffusion, condensed, and condensation-diffusion coatings for protecting turbine blades from hightemperature gas corrosion using this method is presented in literature (Muboyadzhyan et al, 2010;Muboyadzhyan, 2011;Kablov et al, 1999;Kablov et al, 2007). The main chemical systems with these coatings, their abbreviations and applications are given in works (Muboyadzhyan, 2011;Kablov et al, 1999;Kablov et al, 2007).…”

Currently, in many industries, special attention is paid to increasing the reliability and economy of the products. Solving problems requires the use of materials that can work in difficult conditions, which determines the relevance of the problem stated in the article. The purpose of the article was to conduct a critical analysis of coatings developed in Russia that are diverse in composition, technological and operational properties, from the standpoint of the possibility of using them to provide a reliable material protection system under conditions that cause high-temperature gas corrosion and surface layer erosion. The main methods of materials protection were considered in the work: thermal spraying, plasma spraying, electron beam, plasma electric arc cathode spraying, vacuum deposition, chemical-thermal treatment, diffusion coating based on aluminum. Among the more effective methods, the method of self-propagating high-temperature synthesis, the method of high-energy plasma chemistry, the methods of physical deposition in vacuum are noted. The types of coatings were also highlighted and their short characteristics were given. Particular attention was paid to heat-resistant coatings based on refractory enamels since their advantages include low cost and the possibility of applying them directly to parts. A number of technical solutions have been identified that protect the alloys from high-temperature gas corrosion and erosion under long-term operation in aircraft products at high temperatures. The results of the article may be useful for further research since individual developments are uninformative from the standpoint of solving specific problems and require expensive bench testing of the claimed technical result.

TiN/ZrN multilayers can effectively improve the erosion resistance of metals, particularly titanium alloys employed in aero engines. To explore the corrosion damage mechanism of TiN/ZrN nanoscale multilayers (nanolaminate), a novel [TiN/ZrN]100 nanolaminate coating was deposited on Ti-6Al-4V alloys by multi-arc ion plating method. Salt spray corrosion tests and hot corrosion experiment were carried out to evaluate the corrosion resistance of the coating. The corrosion and damage mechanisms were explored with the help of detailed microstructure, phase composition and element distribution characterizations. The salt spray corrosion tests showed that the [TiN/ZrN]100 nanolaminate coating possessed good corrosion resistance, which protected substrate against the corrosion. The low temperature hot corrosion tests showed that the oxidation occurred on the surface of the coating, which improved the oxidation resistance of the sample. However, the oxidized droplets squeezed the coating, and destroyed the oxidized layers. As a result, the coating was peeled off from the substrate. The research highlights the corrosion resistance of the novel TiN/ZrN nanolaminate coating and offers a support for their application in engine compressor blade.
