FIELD: multilayer coatings.
SUBSTANCE: invention is intended to determine the internal (residual) stresses in multilayer coatings created by spraying. The substance of the invention lies in the fact that by means of synchrotron radiation, a series of radiographs are taken, carried out in 2 stages, the first using a symmetrical shooting scheme and the second asymmetric shooting scheme, the determination of the residual stress of a multilayer nanostructured coating is carried out using the sin2Ψ method, and its quantitative calculation is carried out with taking into account the inhomogeneity of the Poisson's ratio.
EFFECT: increasing the reliability of determining internal (residual) stresses in multilayer coatings created by spraying.
