ABSTRAKT

VT6 titanium alloy surface modification is carried out by electroexplosive alloying with a plasma formed in explosion of a titanium foil with a weight powder sample of boron carbides with subsequent irradiation by a pulsed electron beam. The formation of an electroexplosive alloying zone of thickness up to 50 µm with a gradient structure, characterized by the decrease in the concentration of carbon and boron with increasing distance to the treatable surface has been revealed. Subsequent electron-beam treatment of the alloying zone leads to smoothing of the alloying area surface and is accompanied by the formation of a multilayer structure at a depth of 30 µm with alternating layers with different degrees of alloying having the structure at the submicro- and nanoscale level.
