This scientific paper describes the structure, phase composition and mechanical properties of nanocrystalline coatings obtained using the ion beam-assisted deposition technology. The results of computer simulation of IBAD processes for different energy values of bombarding ions and for relationships between the densities of ion fluxes and metal deposition rates is given. The data of electron-microscope analysis of the initial stages of film structure formation (of 5 nm thick and more) is presented. And finally we demonstrate the influence produced by the ion energy and ion current density on the formation of nanocrystalline structure and its correlation with tribological properties of coatings.
