Popis:	In the current work, a typical NiCrAlY alloy and, moreover, amorphous Fe-based alloys are arc-sprayed for the desired application in cryogenic environments. Nitrogen is used as process gas, while the stand-off distance and number of passes were varied. The results demonstrate coatings with low, but varying porosity and oxide content and mostly high electrical conductivity. Especially the amorphous Fe-based coatings reveal homogeneous coating structures and promising properties. Further investigations regarded the deposition efficiency, tensile adhesive strength, hardness, durability under cryogenic conditions and the thermal diffusivity.
