Microstructure and Properties of Laser Cladding Fe-Al Intermetallics
Abstract:
Fe-Al intermetallics coatings are prepared on an aluminum alloy ZL114A by laser cladding pure Fe and Al powders. The microstructure and hardness of the coatings are analyzed by using optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and microhardness testing machines. The results show that a fine surface quality can be obtained under a suitable process parameter of laser. The laser cladding layers are mainly consisted of FeAl, FeAl3, Fe2Al5 and Fe3Al phases. The two cladding layers (60Fe-40Al, 90Fe-10Al) have high microhardness, which achieve HV520 and HV890.
