Особенности структурно-фазового состояния многослойных покрытий на основе Zr-Y-O

Abstract

Using high-resolution transmission electron microscopy it was established that the Zr-Y-O-based coating layers have a ZrO[2] phase in the tetragonal and monoclinic modifications in the initial state. When it is heated up to 900°C, the ZrO[2] phase in the cubic modification appears in the layer of the coating. With an annealing time of 20 minutes, the grains are crushed to a size of about 15-20 nm. The microdiffraction pattern is modified, the number of reflexes of the tetragonal and monoclinic phases first increases, and then changes without systemic.
