“…The works (Muboyadzhyan, 2011;Kablov et al, 1999;Kablov et al, 2007), demonstrate the original technological processes developed at FSUE "VIAM" for producing ion-plasma diffusion, condensed and condensation-diffusion coatings for protecting nickel blade alloys from hightemperature gas corrosion in the temperature range of 1000-1100 °C and 1100-1200 °C. For complex alloying of ion-plasma diffusion coatings, the deposition of condensed nickel-based sublayers is proposed.…”

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.

“…MAP 3 differs from MAP 2 in the possibility of assisted deposition during the bombardment of a substrate by 40 keV gas ions at an ion current density up to 200 μA. Before coating dep osition, the sample surfaces were degassed and then ion etched in a vacuum arc plasma at a bias voltage of 300 V applied to a substrate for 4-5 min in the work ing chamber of a setup before deposition [1,7].…”

“…Such blades represent "open works" with a complex internal space system, which is connected to air con ducting internal space channels and the gas conduit of an engine by a system of perforation holes from 0.2 to 0.8-1 mm in diameter. This structure ensures effective internal jet cooling and external film cooling of the external wall of a blade 1-1.5 mm thick [1][2][3].…”

Heat resistant coatings are considered for the external surface of high pressure turbine (HPT) single crystal blades for promising gas turbine engines (GTEs) made from carbon free nickel superalloys with rhenium or rhenium plus ruthenium. Nickel superalloys covered with heat resistant coatings consisting of heat resistant connecting layers and an external ZrO 2 -(7-8 wt %)Y 2 O 3 ceramic layer are subjected to heat resistance and high temperature tests. The test results are used to choose the heat resistant layer that ensures the highest properties of a composition heat resistant coating. The use of sequential chemical and physical deposition methods for coating layers is shown to be required to protect HPT blades in promising GTEs. Medium frequency magnetron plasmachemical deposition of ceramic layers in heat resistant coatings with a low thermal conductivity is found to be promising.

“…This allows creating wear-resistant multilayer coatings with nanocomposite structure which are characterized by both, high hardness and plasticity. Protective ion plasma sprayed coatings with 2D nanocomposite structure formation, in which the size of structure elements does not exceed 100 nm, on the high-loaded components surfaces is one of the most promising research lines aiming at enhancement of SPE resistance, heat resistance and thermal stability of various products (Kablov et al, 2008).…”

This article presents a description of a test rig for solid particle erosion resistance of construction materials and protective coatings investigation, as well as equipment for preparing products surfaces and protective coatings formation. The authors discuss a method of velocities and trajectories determination of solid particles that impinge on a metal surface using multiple exposure photo registration. The results of a steel 20Kh13 (X 20 Cr 13) specimen with a 2D nanostructured ion -plasma coating solid particle erosion resistance investigation are reported. It is shown that a protective coating increases resistance of blade steel 20Kh13 (X 20 Cr 13) to solid particle erosion by more than twice.
