Titanium matrix composite coatings were prepared on TA15 titanium alloy surface through laser melting depositing pre-mixed TA15+30%TiC powders (volume fraction). The microstructure, the hardness and the interface bonding strength of the coating were investigated. The results show that during the laser melting deposition process, original TiC particulates dissolved and re-precipitated fine TiC in the solidification process. The precipitated TiC presented two different morphologies, i.e. equiaxed and dendrite. There were some unmelted TiC particulates in the coating. The hardness of the coating was up to HRC 60. The coating was metallurgical bonded with the substrate. The interface bonding strength was higher than 310 MPa and the shearing strength of the coating were 330 MPa. There was no debonding after bending and thermal shock tests, indicating the good compatibility of the coating with the titanium alloy substrate
