Краткое описание

Structural and phase changes caused in Armco iron by compression streams are studied. It has been shown that on hydrogen embedding into the surface layer of a sample to a depth not exceeding 0.5 mm, the processing in this mode can he regarded as the thermal effect of plasma flow on surface layers thicker than 1 µm. As a result of the plasma flow treatment, the near surface layers are formed during rapid solidification from a melt. An increase in microhardness from 3.5 ± 0.2 GPa to 5.2 ± 0.6 GPa was observed.
