The paper describes the structure, hardness and wear resistance of electron beam coatings cladded by using of "TiB-titanium binder" composite powders. The powders have been synthesized from titanium and boron powder mixtures by self-propagating high temperature synthesis (SHS) at wave burning mode. The SHS powders were cladded on titanium substrate VT1-0 by electron beam surfacing. A phase composition and a structure of the SHS powders and of the cladded coatings were investigated by X-ray diffraction and optical microscopy. According to structure investigation and hardness measurement in the "coating-titanium base plate" transition zone an adhesion between the coating and the substrate was high. The maximum hardness increase of the coatings strengthened by needle-like titanium monoboride inclusions was 2.2 times and abrasive wear resistance-3.7 times as compared with VT1-0 titanium.
