Abstract
The present work summarises the structure and properties of heat-resis tant coatings produced by the vacuum electron-beam evaporation and con densation of heat-resistant CoCrAlY alloys and ceramics onto a base of partially stabilized zirconia ZrO2-8%Y2O3. Two-layer CoCrAlY/ZrO2 and three-layer coatings in which the metal coating consists of two funct ionally linked layers are considered: the inner layer, plastic, is des igned for relaxation of thermal stresses, whilst the outer layer is to provide protection from high-temperature oxidation.
