Titanium boride layers were produced by plasma paste boriding on Ti6Al4V at 973–1073 K. Formation rates of the Ti boride layers have parabolic character at all temperatures. Boron diffusivities were estimated using a diffusion model including incubation times. Activation energies of boron in TiB2 and TiB were 136 and 63 kJ/mol respectively.
