Increasing of topography homogeneity of the construction materials surface during final ultrasound processing

There was defined a formation at the surface of steel billets during the influence of fluctuating at ultrasound frequencies regular nano-structures indicator. The nano-structures form homogeneous micro layer which differs from the original one by smaller fractal dimension. The possibility to form an orientated micro layer at the surface of thermo-processed billets was shown. The micro layer allows to improve the conditions of contacting for the details of the type of matched friction pairs.
