![]() At the bottom of the coatings, an inhomogeneous mixing zone with an increased concentration of Fe was formed at the “substrate–coating” interface, a thick layer with a Fe50-Ni25-Al25 at. ![]() % Fe, which appeared due to the partial melting of the steel substrate. ![]() The coatings mostly consisted of grains elongated perpendicular to the substrates, with a strong texture along the grain growth direction. The structure of the coatings was investigated using optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), electron backscatter diffraction (EBSD), and X-ray diffraction (XRD). NiAl-based intermetallic coatings were obtained using non-vacuum electron beam cladding on low-carbon steel.
