Multifractal Analysis of the TiN/Al2O3 Coating Surface under HCEB Modification

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 remelt-ing 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.
