Titanium matrix composite coatings were fabricated on Ti-6Al-4V substrate by laser cladding using powder mixtures of Ti+Cr3 C2 and Ti+TiB2 , respectively. The chemical compositions and microstructures of the coatings were analyzed using scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD). Microhardness was measured by a microhardness tester. The results showed that Cr3 C2 particles were dissolved and deposited to form dendritic TiC in the upper section and spherical grain TiC in the bottom of Cr3 C2 +Ti coating. Most of TiB2 was dissolved in the molten pool by laser irradiation, then formed TiB with fine needles and coarse needles in the TiB2 +Ti coating. A few quasi-melted TiB2 particles with irregular shape at the bottom of the coating were observed. The average microhardnesses were approximately HV850—HV1000, HV800—HV1050 in the Cr3 C2 +Ti and TiB2 +Ti coating, respectively, which were 2～3 times higher than that of Ti-6Al-4V substrate.
