METHOD FOR X-RAY DIFFRACTION CONTROLLING PARTS OF GAS TURBINE ENGINE Russian patent published in 2017 - IPC G01N23/20 

FIELD: physics.

SUBSTANCE: radiograph is made for the controlled part on the intended fracture surface from the reflecting plane (11.0) without a background by using the T_i-K_α titanium radiation and from the reflecting plane (01.3) without a background by using the T_i-K_β titanium radiation, determining the parameter depending on the part use, wherein the integrated X-ray parameter is calculated when making the radiograph for the controlled part Δ, wherein the residual resource parameter P_res is used as a parameter depending on the part use_, defined by the predetermined relationship.

EFFECT: increasing the process productivity of controlling the parts by the non-destructive method both in the operation process, and at the stage of the endurance tests.
