Influence of Yttrium Addition on Structure and Properties of MoYSiB Oxidation-Resistant Coatings
https://doi.org/10.56304/S2079562922050220
Abstract
This article describes fabrication of coatings in the MoYSiB system with various yttrium contents by magnetron sputtering of MoSiB/Y mosaic targets. The coatings have been analyzed by scanning electron microscopy, X-ray diffraction, glow discharge optical emission spectroscopy (GDOES), nanoindentation, and high temperature nonisothermal annealing. It has been established that addition of Y to the coating composition leads to decrease in crystallite size of the h-MoSi2 phase, mechanical properties, and resistance of the coatings. A protective film consisting of borosilicate glass with inclusions of Y2O3 crystallites forms on the Y-containing coating surface after annealing at 1300°C.
