FIELD: test equipment.
SUBSTANCE: test specimen of a disc includes a support surface; a test specimen of the blade includes a support surface, onto which the above coating is applied. The blade test specimen consists of two halves having the possibility of coming into contact on both sides of the disc test specimen. The blade test specimen brought into contact with the disc test specimen is subject to tension cycles, during which the test specimens are tested for tension stress relative to each other in tension direction. Tensile deformation is transferred through support surfaces contacting the blade test specimen and the disc test specimen. The coating is evaluated depending on the specified evaluation criterion.
EFFECT: possibility of obtaining highly correlated results with actual evaluations of stability in time of the blade root coatings as those obtained during the blade service life.
