“…Despite continuous improvements and developments, making blades for gas-turbine engines (GTE) is still costly, whereas their wear-out essentially prevents long-term operation of gas turbines. Insignificant geometric deformations that might be sustained in operation render even the most expensive blades useless [1].…”

This paper dwells upon using the VPr11-40N high-temperature brazing powder as a cladding applied by a laser to restore the height of the airfoil of a turbostarter blade in an NK-12MP turboprop, while also making the edge more wear-resistant. It has been found out that laser cladding generates a highly homogeneous structure with lesser gradient of hardness over the clad area compared to furnace brazing. Abrasive-wear tests have shown that this braze resists abrasive wear better than the blade substrate material (superalloy JS6К heat-resistant intermetallic alloy).

“…Single crystals alloys are characterized by the presence of primary carbides of spherical, block or script-like morphology [14][15][16][17][18][19]. The main method for studying such fine structures is x-ray spectroscopy, which fully makes it possible to determine the main characteristics of the fine structure [20][21][22][23][24].…”

In this work, theoretical modelling of the thermodynamic processes of the release of excess phases is carried out using the CALPHAD method. As well as a practical study of the structure and distribution of chemical elements in carbides, depending on alloying using scanning electron microscopy. It has been established that in typical carbides, for the system Ni-11.5Cr-5Co-3.6Al-4.5Ti-7W-0.8Mo-0.06C, there is a tendency to degeneration and phase reactions depending on the level of alloying with the given elements. The mathematical dependences of the influence of alloying on the temperature of precipitation (dissolution) of carbides and the change in the chemical composition of the alloy on the content of elements in carbides are established. The obtained dependences were experimentally confirmed using scanning electron microscopy on nickel-based superalloys.
