“…It is well known that the wear resistance of materials is highly susceptible to the microstructure and properties of the material surface [4]. Many techniques are used to obtain surfaces with a high resistance to wear, such as mechanical processing, chemical processing, laser processing, plasma processing, gas nitriding, ion implantation, and many others [1,[3][4][5][6]. Recently, materials with a nanocrystalline structure (NCS) in the top surface layer have been considered as promising candidates for operation in such severe conditions [7][8][9][10][11].…”

A surface nanocrystalline steel layer in the low alloy steel 41Cr4 was fabricated by using mechanical-pulse treatment (MPT) with different deformation modes. The structure parameters, the physical and mechanical properties, the wear resistance, and the surface topography parameters of the treated steel depending on the deformation mode were investigated. A tool with a smooth working surface was used for inducing unidirectional deformation in the top surface layer (shear), and a tool with the oppositely directed grooves was used for generating multidirectional deformation. The surface layer with a nanocrystalline structure formed by MPT using both of the tools was characterised by enhanced mechanical properties and wear resistance compared with those of the untreated or heat-treated steels. Inducing multidirectional deformation during the MPT resulted in a decrease in the grain size and an increase in the depth and microhardness of the surface layer due to it facilitating the generation of dislocations compared to those formed under unidirectional deformation. The results also demonstrated that favourable surface topography parameters providing the highest wear resistance of the steel were obtained at MPT using multidirectional deformation.
