Ai. Rybnikov et al., THE STRUCTURE AND PROPERTIES OF METAL AND METAL-CERAMIC COATINGS PRODUCED BY PHYSICAL VAPOR-DEPOSITION, Journal of materials processing technology, 55(3-4), 1995, pp. 234-241
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.
