The paper presents the results of the laser alloying of the surface of Ti-6A1-4V alloy carried out to modify the phase composition of the alloyed zone. Laser treatment was performed on samples coated by graphite and TaB2 powders mixture in order to form titanium borides and carbides as a consequence of the laser irradiation. Topography of the surface of laser melted layer was investigated. The laser melted zone was examined and its microstructure and chemical composition were determined by optical microscope and scanning electron microscope equipped with EDS X-ray detector. The phase composition was investigated using X-ray diffractometry. The Vickers hardness was measured on the surface of crosssections. Abrasive wear resistance was a criterion of the surface layer enrichment efficiency. Laser treatment bas produced surface layer which consists of hard TiC, TiB, TaB2 particles spaced in ductile martensitic matrix. The hardness of the layer increases clearly in comparison with the base material.
