Abstract

The developed in CIAM methods, the samples design and the equipment for experimental research of strength properties and factor of temperature expansion of real thickness thermal barrier coatings (TBC) layers at working temperature are considered. Results of determination of properties of NiCrAlY+ ZrO2?Y2O3 coatings made by serial technology are given.
