© 2020 by Begell House, Inc.Austenitic steel (18% Cr, 10% Ni) surface layer structure, phase and element composition after compression plasma flows treatment (at the energy absorbed by the surface layer 25 J/cm2 per pulse) have been investigated in this work. The findings showed that plasma impact led to the formation of the crystallized after-melting layer with the thickness of ~ 20 µm after 7 plasma pulses containing columnar-like crystallites of γFe with the diameter of ~ 0.5 µm grown in the <100> direction and oriented almost perpendicularly to the surface. The weight loss of steel samples was linearly dependent on the number of pulses. The mean value of the weight loss for steel during plasma impact was 2.6 mg/cm2 per pulse, which was greater than that for iron (0.74 mg/cm2 per pulse). The interaction of oxygen from the vacuum chamber and outward diffusion of titanium and aluminum from the bulk of steel resulted in the formation of the surface discontinuous oxide film containing Ti and Al atoms.
