N2 - The synthesis of hard composite coating on titanium alloy by laser cladding of Al/Fe/Ni+C/Si 3N 4 pre-placed powders has been investigated in detail. SEM result indicated that a composite coating with metallurgical joint to the substrate was formed. XRD result indicated that the composite coating mainly consisted of γ-(Fe, Ni), FeAl, Ti 3Al, TiC, TiNi, TiC 0.3N 0.7, Ti 2N, SiC, Ti 5Si 3 and TiNi. Compared with Ti-3Al-2V substrate, an improvement of the micro-hardness and the wear resistance was observed for this composite coating.
