Abstract
New experimental results are presented on the structure and phase composition of hybrid coatings,
which were deposited on a substrate of AISI 321 stainless steel using a combination of plasma-detonation
and subsequent High-Current Electron Beam (HCEB) treatment. Modes of processing at which the remelting
of the material, which allows to obtain high adhesion of protective layers to the substrate surface are
selected. Statistical parameters are calculated within two dimensional multifractal detrended fluctuation
analysis. It is shown that the generalized Hurst exponent of the surface under modification is determined
by a beam current.
