Abstract
The article present results of investigations of structure, phase composition and microhardness of thermal barrier plasma coatings produced by using quasi-crystalline alloy AlCuFe with a different content of the ψ-phase as a bond coat material instead of traditional alloy MeCrAlY (Me-Ni, Co, Fe). Formation of phases in the ceramic ZrO2 layer was studied depending upon the ψ-phase content in the bond coat of a thermal barrier plasma coating.
 
 
Keywords: thermal barrier plasma coatings, powders, zirconia, alloy AlCuFe, quasi-crystalline phase, structure, coating properties
