“…This is indicated by the presence of the following crater types: multi-ring, adjacent and nick-like. It is known (Shulov et al, 2015) that craters of such types are the most dangerous with respect to corrosion resistance (Figure 6).…”

“…analysis of the performed investigations shows (Kablov, 2001;Shulov et al, 2010;Shulov et al, 2013;Shulov et al, 2015;Kosmin and Budinovsky, 2016) that both character and intensity of turbine blade damages at high temperature corrosion are determined by the following factors: (i) anti-corrosion properties of protective coatings, (ii) level of active static and vibration loads, (iii) operating temperature of turbine blades, as well as (iv) concentration of corrosion-active substances in fuel combustion products. In some cases, high-temperature corrosion acts as an independent disturbing factor (Budinovskii and Muboyadzhan, 2003;Shejko et al, 2017;Ivanov et al, 2018;Braceras et al, 2018).…”

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.

“…However, for every 1% reduction in efficiency, the fuel consumption of the aero-engine will increase by 2%. Therefore, it is necessary to monitor the blade tip clearance in real-time to obtain the blade operation status in advance and provide a strong guarantee for the safe operation of the aero-engine [4] .The common measurement methods of tip clearance include probe measurement, capacitance measurement, eddy current measurement, microwave measurement, ultrasonic measurement, reflection intensity measurement, interference intensity measurement, and laser measurement [5] . The optical fiber measurement method has a fast response, strong anti-electromagnetic interference ability, and high reliability, and is suitable for working in harsh, high-temperature, and high-pressure environments.…”

A novel non-contact detecting method of aero-engine blade tip clearance based on an optical fiber sensing system is presented. To eliminate the sensor measurement error caused by the slight change of the reflectivity value of the mechanical end face when the light source angle fluctuates and rotates, a three-coil coaxial fiber bundle sensor is proposed. Relevant experimental results show that the system has the advantages of high measurement sensitivity, small sensing probe volume, strong electromagnetic interference resistance, and high reliability. The application of this technology provides an effective method for dynamic radial gap detection of high-speed rotating machinery.

“…At present, special attention is paid to the development of high-intensity methods of surface engineering of engineering parts of a fairly wide range, as well as their extremely rapid implementation of technological processes created on their basis in the industry. One of the demanded tools for surface engineering can be using high-current pulsed electron beams (HCPEB) of microsecond duration to modify the surface and near-surface layers of parts (Novikov et al, 2010;Uglov et al, 2011;Shulov et al, 2012;Gromov et al, 2013;Shulov et al, 2014;Shulov et al, 2015). The study of the effect of HCPEB irradiation on the surface of the layers of the heatresistant multicomponent ion-plasma coating Ni-Cr-Al-Y under various conditions, as well as the analysis of structural-phase changes occurring upon modification, were the objectives of this work.…”

The development of aerospace engineering and mechanical engineering directly depends on the development of new metal materials and advanced technologies. The problem of creating materials and their types of processing to increase the level of operational properties is relevant in connection with the complication and tightening of working conditions of modern technologies. One of the most important tasks of contemporary aircraft construction is to increase the operational properties of the surface layer. The purpose of the article is to elucidate the effect of high-current electron beams of microsecond duration on changes in the surface layers of the heat-resistant multicomponent ion-plasma coating Ni-Cr-Al-Y under various conditions. Using a complex of metallophysical research methods, the physicochemical and structural-phase states of the surface layer were studied before and after modification of the samples. These samples were coated with heat-resistant condensed ion-plasma coatings of three different compositions using nine high-current electron beams in 9 modes with different values of electron energy and number of pulses in the selected interval of electron energy. An analysis of the structural phase changes occurring during modification was carried out. Cylindrical samples of targets made of heat-resistant nickel alloy ZhS36 coated with ion-plasma condensed multicomponent coating SDP-2 + VSDP-16. These samples were used according to serial technology, both with subsequent modification using highcurrent electron beams and without modification. It was found that chromium in the initial state is unevenly distributed: chromium is present in the particles; the matrix is depleted in chromium. The research results can be useful for scientists to study the properties of heat-resistant multicomponent ion-plasma coatings Ni-Cr-Al-Y and the effect of high-current electron beams on it, as well as for the manufacture of more heat-resistant materials in aerospace engineering and mechanical engineering.
