The influence of ultrasonic impact treatment (UIT) in an inert atmosphere on the structure, phase composition and micromechanical properties of composite coatings formed by embedding of dispersed particles of Al$_{2}$O$_{3}$, B$_{4}$C, BN hardening powders and carbon nanotubes into the surface layers of D16 aluminium alloy is investigated. Under influence of severe plastic deformation caused by UIT, a partial grinding and introduction of powder particles and the nanostructurization of matrix alloy with the deformation composite layers take place. The observed maximum strengthening (200—350%) and durability increase ($\cong$ 7 times) of D16 alloy surface occur due to reinforcement by Al$_{2}$O$_{3}$ and B$_{4}$C particles.
Key words: ultrasonic impact treatment (UIT), surface nanocomposite, severe plastic deformation, quasi-hydrostatic compression, durability.
