In situ reaction synthesized TiB reinforced titanium matrix composites were fabricated using rapid non-equilibrium synthesis techniques of laser cladding. Titanium matrix composite were laser cladding treated on Ti-6Al-4V using Ti and B powder mixture, and the designed weight fractions of B were 10 wt.% in the starting powder mixture. The composite coating mainly consists of α-Ti and TiB. The reinforcement TiB is dispersed homogeneously in the composite coating with pre-placed powder thickness of 0.5mm. The influence of pre-placed powder thickness on microstructure of laser cladding coatings was discussed.

A titanium matrix composite coating reinforced by in situ synthesized TiB and TiC was deposited on Ti6Al4V by laser cladding. Microstructural analyses were made by means of X-ray Diffraction (XRD), Optical Microscopy (OM), Scanning Electron Microscopy (SEM) and Electron Probe Micro-Analysis (EPMA). The solidification process was also discussed in detail. The results show that the coating is composed of -Ti cellular dendrites and a eutectic in which a large number of needle-shaped TiB whiskers and a few equiaxial TiC particles are embedded. A thin dilution zone with a thickness of 50 m is observed at the interface, and consists of a few TiB and TiC and a large number of lamella grains in which a thin needle-shaped martensitic microstructure is exist. The solidification process could be divided into four stages: nucleation and growth of primary -Ti phase, precipitation of a binary eutectic -Ti+TiB, precipitation of a ternary eutectic -Ti+TiB+TiC and solid transformation from -Ti to -Ti.
