Fe-Al Intermetallics coatings are prepared on ZL101 substrate by laser cladding pure Fe and pure Al powders. The microstructure and hardness of the coatings and interface between the coating and substrate are analyzed by using optical microscopy, SEM, X-ray diffraction (XRD), and microhardness testing machines. The results show that the bonding zones between substrate and coatings are sawtooth-liked structure. The coating mainly constitute of FeAl and Fe3Al phases. All the three coatings (Fe-Al, 2Fe-Al and 3Fe-Al)have high microhardness, which achieve 744 HV, 603 HV and 795 HV respectively.
