Abstract
Investigation of phase and element composition of iron modified by compression plasma flows generated by quasi-stationary plasma accelerator has been performed. The energy density absorbed by the sample surface was about 15 J/sm2 per pulse that under the test conditions corresponds to the flow power density of 1.5Ã105 W/cm2. According to Auger spectroscopy data, concentration of nitrogen in the surface layer reached to â¼20 at%. Modified layer with the thickness of tens of micrometers containing ε-Fe2+xN phase and nitrogen austenite (γN) has been formed.
