摘要

The wear resistance of steel 45 in oil-abrasive medium with surface nanocrystalline structure formed by severe plastic deformation using the energy of high-speed friction with additional alloying with chrome and nickel from special technological media during mechanical-pulse treatment is studied. The increase in wear resistance of steel caused by surface alloying during mechanical-pulse treatment, compared with the same treatment without surface alloying, is shown. This increase is explained by the formation of the nanostructure with a smaller grain size and higher microhardness, as well as the alloying elements effect on the structure formation with lower electrochemical potentials, which are more favourable for secondary structures formation by surface activation during wear resistance tests.
