Rhenium in single crystal nickel-based superalloys for gas turbine engine blades

Development of new materials for hot duct components, including those for the gas turbine engines of the VI generation, is a high priority task. Single crystal nickel-based superalloys for gas turbine engine blades and directional solidification technology created by VIAM allow to increase the gas temperature at the turbine inlet and therefore to improve power density, efficiency and service life of gas turbine engines. Experimental results concerning an effect of alloying elements, particularly rhenium, on the physical, chemical and structural parameters of single crystal nickel-based superalloys are given. It was shown that rhenium is more efficient than tungsten, molybdenum and other alloying elements to increase rupture strength of single crystal nickel-based superalloys.

Keywords: single crystal nickel-based superalloys, segregation of elements, microstructure, phase stability, rhenium

Development of an experimental technology for production of VZHL21 superalloy castings

An experimental technology for casting of blades from new nickel-based superalloy (VZHL21) was developed. Design of feeding gate system was selected and researched. The mold composition was chosen on the base of experiments. Some optimal parameters of investment casting of blades for terrestrial gas-turbine engine NK-36ST were determined: temperature of the ceramic mold, temperatures of alloy overheat and pouring. An influence of processing conditions of casting and ceramic mold composition on macro- and microstructure was studied. Researches of an experimental batch of casting blades were performed by nondestructive methods (NDT methods) to detect metallurgical defects. Macrostructure and microstructure of cast blades of an experimental batch were investigated.

Keywords: superalloys, investment casting, ceramic mold, blade, macrostructure, microstructure

Modern methods for deposition of thermal barrier coatings on GTE turbine blades

The article describes two methods of deposition of a ceramic thermal barrier coating (TBC) on turbine blades, which are widely used in mass production of gas turbine engines (GTE) - electron beam physical vapor deposition (EB-PVD) and atmospheric plasma spraying (APS). Further trends in development of these methods - electron beam directional vapor deposition (EB-DVD), production of TBC with directional vertical cracks (DVC), solution precursor plasma spraying (SPPS) are described as well. Some new processes for production of TBC such as plasma spraying physical vapor deposition (PS-PVD) and magnetron medium frequency sputtering of Zr- and Hf-based targets being under developing at VIAM are considered. Differences in microstructures, thermal conductivity, heat- and erosion resistance of the produced coatings are also discussed.

Keywords: thermal barrier coating (TBC), YSZ, gas turbine engine, atmospheric plasma spraying (APS), electron beam physical vapor deposition (EB-PVD), plasma spraying physical vapor deposition (PS-PVD)

Thermal diffusion processes for saturation of internal surface of GTE turbine blades made of advanced high temperature superalloys with refractory elements and carbon

The processes for formation of a barrier layer based on rhenium, tantalum or carbides of refractory elements for the subsequent deposition of a diffusion aluminide coating to protect the internal surface of single crystal blades of GTE made of rhenium- and rhenium-ruthenium bearing superalloys were considered. It was shown that the barrier layer prevents formation of the secondary reaction zone (SRZ) under the heat-resistant coating in case of long-term exposure to high temperature, which causes the alloy softening. Phase composition of the surface layer of a heat-resistant alloy was studied after diffusion saturation of its surface with rhenium, tantalum and carbon. Kinetics of powder carburizing of rhenium- and rhenium-ruthenium bearing superalloys and phase composition of the surface layer upon carburization process was investigated.

Keywords: turbine blades, carbon-free heat-resistant rhenium and rhenium-ruthenium bearing Ni-based alloy, high-temperature gas corrosion, thermal diffusion heat-resistant coatings, internal surface of blades, barrier layer, thermal diffusion saturation of the surface with carbon, thermal diffusion saturation of the surface with rhenium, thermal diffusion saturation of the surface with tantalum, secondary reaction zone (SRZ), topologically close-packed phases (TCP phases)

Technology for production of ion-plasma heat-resistant bonding sub-layers with increased aluminum content for advanced TBCs

Possibility of formation of ion-plasma heat-resistant bonding sub-layers for thermal barrier coatings (TBCs) with an increased content of aluminum in β-phase was considered. It was shown that during cyclic tests of TBCs with (Ni-Cr-Al-R)+(Al-Ni-Y) sub-layers, where R - Y, Ta, Re and H, at 1150-1200°С, chipping of the ceramic layer of TBC happened after 30-40 cycles. Microstructural studies of specimens after thermal cycling tests showed the presence of refractory elements (diffused from the condensed layer of the coating) in the heat-resistant bonding layer. That caused a critical growth of bonding oxide layer and, as a consequence, chipping of the ceramic layer. A technology of double-staged aluminizing of the heat-resistant sub-layer was suggested for elimination of this defect. Upon deposition of an Al alloy layer on the condensed layer, it was subjected to vacuum diffusion annealing followed by deposition of the second Al layer and a repeated annealing. It was shown that an increase in aluminum content in the external layer of the heat-resistant coating provides formation of homogeneous oxide layer of lower thickness that increases the time before chipping of the ceramic layer more than two times.

Keywords: ion-plasma coatings, heat-resistant coatings, thermal barrier coatings, heat-resistant bonding layers, thermally grown oxide

Study of damping capacity of ion-plasma coatings

The possibility of application of ion-plasma coatings to reduce the oscillatory amplitude of the free end of VT6 titanium alloy specimens was shown. Coatings were deposited by high-energy vacuum-plasma technology. The tests were conducted on a vibro-dynamic stand under conditions of the first bending mode resonance. It was shown that the factor of merit of the oscillating system could be used for evaluation of the damping capacity of ion-plasma coatings.

Keywords: high-energy vacuum-plasma technology, ion-plasma damping coating, factor of merit, damping decrement

Ring magnets with radial texture for dynamically tuned gyroscopes

Magnets are used as components of dynamically tuned gyroscopes (DTG) and accelerometers, which are the basic devices for the inertial navigation. An optimum design of magnets for dynamically tuned gyroscopes (DTG) is a ring magnet with radial texture (RMRT). The article is focused on the production technology of RMRTs and methods of their control. Calculations of the shrinkage of a ring magnet with radial texture, the field at the axis and texture inclination angle in its plane have been made. It was demonstrated that theoretical calculations of parameters are closely correlated with experimental data for the material of the following composition (%at.): (Nd 0.93Dy 0.07) 15.5(Fe 0.99Co 0.,01) restAl 1.1Ti 1.3B 6.7. It was found out that the main inhomogeneity of the texture is located in the area adjacent to the inner diameter of the ring

Phase composition of Nd-Dy-Fe-Co-B sintered materials

Nd-Dy-Fe-Co-B materials are used for production of ring magnet with radial texture (RMRT). Magnets are used as components of dynamically tuned gyroscopes (DTG) and accelerometers, which are the basic devices in the inertial navigation. An optimum design of the magnet for dynamically tuned gyroscopes (DTG) is a ring magnet with radial texture (RMRT). The article is focused on the study of phase composition of Nd-Dy-Fe-Co-B sintered materials. It is demonstrated that the phase composition of (Nd 1- хDy х)-(Fe 1- уCo у)-B sintered materials is influenced by Co content. The phase (Nd, Dy)(Fe, Co) 4B is found out at (Nd 1- хDy х)-(Fe 1- уCo у)-B sintered materials. It is shown that the content of the main magnetic phase (Nd, Dy) 2(Fe, Co) 14B is reduced sharply with increasing Co content. Approximating polynomials correlating composition of (Nd1-хDyх)-(Fe1-уCoу)-B material with that of the main magnetic phase (Nd1-хDyх)2(Fe1-уCoу)14B and allowing determination of (Nd, Dy) 2(Fe, Co) 14B phase composition were found.
