Abstract

The surface relief and structure peculiarities of steel 45 after electroexplosive copper plating and subsequent electron beam treatment were investigated by scanning and transmission electron microscopy methods. It has been 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 hardness growth of surface layer under the small pulse number (5 and 10 pls.). The further increase of irradiation pulses number leads to essential decrease of surface layer hardness.
