Item Simulation of the Formation of Protective Coatings using the Radial Distribution Function of Atoms(Dnipro State Technical University, Kamianske, Ukraine, 2023) Sereda, Borys; Baskevich, Oleksandr; Gulivets, Alexey; Udod, AndreyENG: Studies of the structural factors of alloys, carried out using wide-angle and small-angle X-ray studies, allowed us to identify general patterns for various alloys. The use of apodization of the Fourier distribution of X-ray diffraction (XRD) contributes to the leveling of the effect of the break in the experimental intensity curve and facilitates close-order modeling. It was established that the height of the main peak of the structural factor decreases, and the position slightly shifts towards larger angles when the arrangement of alloys increases. The second maxima of the structural factor have an asymmetric shape, which varies depending on the conditions for obtaining the alloys. As the amount of phosphorus in the alloys decreases, the relief and height of the peaks increase. It was found that the diversity of the close order of the alloys is related to the deposition conditions, in particular, to a large value of the overvoltage at the cathode and the penetration of phosphorus atoms into the structure of the alloys. The obtained modeling results allow us to establish the conditions for the formation of close order in alloys and expand our understanding of the structural features of materials.
