“…The most loaded unit of aircraft engines is the blade of the first stage of the turbine, which, due to the high thermal stress and corrosion of the external environment, has a short service life of the aircraft engine as a whole [10,11,18,19].…”

With the active development of the mining sector, the share of open pit mining is increasing. It should be noted that the increase in the volume of open-cut mining depends on the volume and methods of excavation works. The main technological equipment performing up to 80% of the total volume of excavation and movement of minerals in open pit operations is hydraulic excavators. Consequently, efficient and highly productive operation of a hydraulic excavator directly affects the efficiency and profitability of mining operations. An important factor of development of mining industry today is to improve the reliability of technological machinery, namely energy efficiency, durability and maintainability of equipment. At the modern stage of development of mining equipment, the use of mine excavators with a hydraulic drive of the working mechanism occupies a wider and wider niche

The influence of various coatings on the corrosion resistance of the valve stem of shut-off valves has been studied. To assess the quality of the obtained coatings, microhardness, corrosion resistance, deformation-strength and tribological characteristics were determined. Researches have shown that the most optimal way of anticorrosion protection for the shut-off valve stem is chromium-plating, which provides corrosion proofing, increases wear resistance and surface microhardness

“…Owing to the use of such coatings, a higher operating efficiency of the turbine blades can be achieved, as less cooling air is needed to maintain the temperature of the blade or shroud. In addition, the service life of the parts increases, because the rate of change in the metal temperature decreases as a result of the heat-insulating effect [5].…”

Ion-Plasma Spraying and Electron-Beam Treatment of Composite Cr-Al-Co-ZrO2-Y2O3 Coating on the Surface of Ni-Cr Alloy

The blades of modern gas turbine engines are complex structures made of heat-resistant nickel alloys with a complex system of internal cavities. The article describes a method of strengthening samples of a heat-resistant Ni-Cr alloy by applying a composite coating (Cr-Al-Co + ZrO2-Y2O3). The alloy prototypes were fabricated by vacuum melting. An ion-plasma technology of a two-layer coating with an inner metal and an outer ceramic layer on the prepared surface of the heat-resistant alloy matrix was developed. The morphology and structure of the alloy prototypes and the investigated composite coating were studied by scanning electron spectroscopy. The total thickness of the two-layer wear-resistant coating was 17–18 μm. The thickness of the inner layer (Cr/Al/Co) is 10–11 μm and the thickness of the outer ceramic coating (ZrO2-Y2O3) is 6–7 μm. To improve the operational characteristics of the material, an electron-beam surface treatment was proposed. The research results showed a sevenfold increase in surface resistance compared with the initial state.
