A wear resistant hard particles reinforced intermetallic composite coating is fabricated on TA15 titanium alloy by the laser cladding process using 54.51Ti-37.68Ni-7.81B4C powder blends as the precursor materials. Microstructure and worn surface morphologies of the coating are characterized by optical microscopy (OM), scan electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDS). Wear resistance of the coating is evaluated under abrasive wear condition. Results indicate the hard particles including additional B4C and in situ synthesized titanium boride and titanium carbide are uniformly distributed in the TiNi/Ti2Ni dual-phase intermetallic matrix. The coating has high hardness and exhibits excellent wear resistance. The mainly wear mechanism of laser clad coating is slight micro-cutting and plastic deformation.
