“…The FS approach can also be used to deposit multiple layer o top of each other, known as multi-layer friction surfacing (MLFS) or friction surfacing layer deposition (FSLD), leading to a solid-state layer deposition process. For coating applications, i.e., deposition of one single layer, FS was successfully performed for various material combinations like steels [12], aluminum alloys [13], copper [14], titanium alloys [15], Inconel [16], magnesium alloys [17], and, e.g., aluminum and steel [18] or low carbon steel over Inconel [19]. Further very challenging dissimilar material combinations are also achievable, as, e.g., Al/Ti joints enabled by hybrid approaches of friction stir welding (FSW) assisted by FS [20].…”

Friction surfacing (FS) is a solid-state layer deposition process for metallic materials at temperatures below their melting point. While the bonding of the deposited layers to the substrate is proven suitable for coating applications, so far the mechanical properties of additively manufactured stacks have not been systematically investigated. In particular, the effect of successive deposited FS layers, i.e., repetitive thermo-mechanical loading, on the interface properties as well as anisotropy and strength of the deposited stack is unknown. For this purpose, the mechanical properties of FS deposited multi-layer stacks from dissimilar aluminum alloys have been investigated, characterizing layer-to-layer as well as layer-to-substrate bonding interfaces via micro-flat tensile testing. Furthermore, directional dependencies in the stack and failure mechanisms are analyzed. The results show a homogeneous, fine-grained microstructure with average grain sizes between 4.2 and 4.6 μ m within the deposited material. The resulting tensile properties with no significant directional dependency present an ultimate tensile strength between 320 and 326 MPa exceeding the strength of the AA5083 H112 consumable base material. No difference was obtained in terms of layer-to-layer or layer-to-substrate interface strength. Furthermore, homogeneous hardness was observed within the deposited structure, which is in the range of AA5083 base material’s hardness of 91 HV. The results indicate that the FS process in conjunction with the material used is suitable for additively generated structures and highlight the potential of this solid-state layer deposition technology.

“…Among these, iron aluminides with higher Al content such as Fe 3 Al (DO 3 ) and FeAl (B2) due to their low cost, are being possible substitute materials for high-temperature applications up to 1000 • C in aggressive environment [5][6][7][8][9]. However, iron aluminides have been poorly studied in the environment composed of (Na 2 SO 4 -V 2 O 5 ) molten salt.…”

Corrosion behavior of FeAl-based alloys containing carbon produced through arc melting in argon atmosphere has been studied at 500 °C to 700 °C. The samples were tested in the aggressive environment of molten salts (80%V2O5/20%Na2SO4). The corrosion behavior was observed by weight change method and the layer products formed were examined by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The different phase components were observed in the surface layer after the test in Fe-22Al alloy. A protective Al2O3 layer was confirmed for Fe-22Al alloy containing carbon only. However, an additional TiO layer was also observed in Fe-22Al alloy containing carbon with Ti addition. The microstructural and XRD examinations revealed that this additional TiO layer protects better against penetration of corrosive media. The corrosion resistance behavior of FeAl-based alloys were addressed on the basis of microstructural evidence.
