【 摘 要 】

Complex modification of a surface of commercially pure titanium is realized. Firstly plasma is created by electrical explosion of a carbon-graphite fiber, of which surface was placed nanosized TiB2powder. Then the surface of technically pure titanium is processed with this plasma. Finally, the modified surface was irradiated by an electron beam. Formation of multi-layer multiphase nanosized structure is revealed. It is shown that the maximum microhardness reached in a near-surface layer exceeds microhardness of a initial material more than by 10 times. Wear resistance of a blanket increases in 7.5; the friction coefficient decreases by 1.15 times.
