Pecularities of the steel electroexplosive copper plating and subsequent electron-beam treatment

Annotation

The surface relief and structure peculiarities of steel 45 (0.45 wt. % С) after electroexplosive copper plating and subsequent electron beam treatment are investigated by methods of scanning and transmission electron microscopy. It is established that the copper concentration in surface layer is increased in 2 times with the growth of electron beam pulses number. The high speed crystallization of modified layer is accompanied by microhardness growth of surface layer under the small impulse number (5 and 10 pls.). The further increase of irradiation pulses number leads to essential decrease of surface layer microhardness.
