FIELD: technological processes.
SUBSTANCE: invention relates to a method of forming a nanocrystalline surface layer on parts made from nickel-based alloy (versions) and can be used to treat gas turbine engine blades and plants to improve their operational characteristics. Surface layer is ion-bombarded until an amorphous layer is formed, followed by exposure of the amorphous layer to ultrasonic oscillations to obtain nanocrystals of given dimensions and fixing the structure of the nanocrystalline surface layer by cooling. Surface layer is bombarded by implantation of La or Yb ions at energy from 35 to 40 keV, dose from 8.0⋅1016 cm-2 up to 1.6⋅1017 cm-2, and nanocrystals are obtained with size in range of 10…700 nm.
EFFECT: disclosed is a method of forming a nanocrystalline surface layer on parts made from nickel-based alloy (versions).
