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. Statistical parameters are calculated within two dimensional multifractal detrended fluctuation analyses. It is shown that the generalized Hurst exponent of the surface under modification is determined by a beam current.
