“…Nickel alloys are designed to form alumina as a protective oxide and have well-developed aluminide coating systems due to their extensive use in aircraft engines 62 . However, coatings are much less developed for refractory alloys and typically contain metal silicides, which have limited protection below 850 °C and fall off above 1700 °C due to aeroshearing 63,64 . A wide range of potential coating failure modes need to be considered during design, and while there has been considerable progress on understanding the mechanics of coatings 57,65 , often, the material properties are missing.…”

Hypersonic vehicles must withstand extreme conditions during flights that exceed five times the speed of sound. These systems have the potential to facilitate rapid access to space, bolster defense capabilities, and create a new paradigm for transcontinental earth-to-earth travel. However, extreme aerothermal environments create significant challenges for vehicle materials and structures. This work addresses the critical need to develop resilient refractory alloys, composites, and ceramics. We will highlight key design principles for critical vehicle areas such as primary structures, thermal protection, and propulsion systems; the role of theory and computation; and strategies for advancing laboratory-scale materials to manufacturable flight-ready components.

“…To synthesize high-temperature oxidation and corrosion-resistant coatings using the pack cementation technique, metallic substrates (e.g., Ni-based or Co-based superalloys, Fe-based alloys, or titanium alloys [10,17]) are placed in a thermodynamically semi-closed system [16] containing powders of a deposition source (e.g., Al, Si, Cr, B 4 C), a halide activator (e.g., NH 4 Cl, NH 4 F, MgF 2 , KBF 4 ) and an inert diluent (e.g., A1 2 O 3 , SiC) [18][19][20]. Thus, different types of pack cementation processes including aluminizing [21][22][23], chromizing [24][25][26], siliconizing [27,28], and boronizing [29][30][31] are utilized among which the first one is extensively used [19].…”

In this research, the pack cementation method was employed to apply a uniform aluminide coating on a substrate of nickel-based superalloy. The obtained intermetallic coating was synthesized using a pack containing 18Al–80Al2O3–2NH4Cl (wt.%) as the main deposition source, an inert filler, and an activator, respectively. The surface morphology and topography, cross-sectional microstructure, the elemental and phase composition, microhardness of the synthesized aluminide coating were studied using atomic force microscopy (AFM), optical microscopy (OM), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), x-ray diffraction (XRD), and Vickers microhardness indenter as the characterization techniques. According to the 3D topography results, the average surface roughness of the Inconel-600 substrate was about 2.446 ± 0.239 nm compared to 43.558 ± 3.876 nm measured for the produced aluminide coating. Additionally, the synthesized coating consisted of NiAl and Ni2Al3 as major phases considering the XRD spectrum. It is also observed that the deposited aluminide coating had a three-layer structure including an outer layer, an inner layer, and a diffusion zone. The Vickers microhardness measurements indicated a significant increase in the microhardness of the substrate (from 185.6 ± 15.8 Hv to 1130.4 ± 42.5 Hv) after applying the aluminide coating. Moreover, the microstructural variations across the deposited aluminide coating led to different microhardness values obtained for each layer. The highest microhardness was observed in the coating diffusion zone, whereas the lowest value belonged to the outer layer.

“…However, niobium is not resistant to high temperature oxidation. It is oxidized at over 350°C and needs surface protection against material degradation [4][5][6][7]. Various techniques may be used for refractory metals coating, including APS, HVOF, laser alloying, PVD (arc sputtering) and CVD (pack cementation).…”

In this paper, thermal oxidation resistance of silicide-coated niobium substrates was tested in a temperature range of 1300-1450°C using an HVOF burner. Pure niobium specimens were coated using the pack cementation CVD method. Three different silicide thickness coatings were deposited. Thermal oxidation resistance of the coated niobium substrates was tested in a temperature range of 1300-1450°C using an HVOF burner. All samples that passed the test showed their ability to stabilize the temperature over a time of 30 s during the thermal test. The rise time of substrate temperature takes about 10 s, following which it keeps constant values. In order to assess the quality of the Nb-Si coatings before and after the thermal test, light microscopy, scanning electron microscopy (SEM) along with chemical analysis (EDS), X-ray diffraction XRD and Vickers hardness test investigation were performed. Results confirmed the presence of substrate Nb compounds as well as Si addition. The oxygen compounds are a result of high temperature intense oxidizing environment that causes the generation of SiO phase in the form of quartz and cristobalite during thermal testing. Except for one specimen, all substrate surfaces pass the high temperature oxidation test with no damages.
