Abstract
Comparative characteristics of multilayer plasma coatings ZrO₂-NiCrAlY are given. It is established that phase composition of the external ceramic layer depends on thickness of the metallic interlayer, i.e. its thermal conductivity that affects the rate of cooling of the ZrO₂ particles deposited on it. Thickness of the metallic interlayer should not exceed 100 mm to ensure optimal heat resistance of the ceramic layer.
 
 
Keywords: zirconia, alloy NiCrAlY, powders, plasma spraying, multilayer coatings, phase composition, structure, heat resistance of coatings
