The laser is an important tool in the processing of metals and implies drilling, welding, annealing, cleaning and hardening of a metal surface and other applications. Our previous study has shown that it is possible to form a submicron-structured surface of steel with surface wettability angle anisotropy. This effect was explained by the formation of laser-induced periodic surface structures (LIPSS) on the surface of steel using powerful pulsed Nd:YAG laser. The LIPSS can be used to control surface tribological properties. The aim of this study is to develop laser technology to form the metal surface with controlled anisotropic tribological properties. To achieve this aim, the surface of cylindrical shape steel samples were irradiated by Nd:YAG laser in order to obtain LIPSS perpendicular and parallel to motion direction. The samples were treated with following laser parameters: λ = 1064 nm, W = 41 mJ, τ = 6 ns, hatch spacing 0.4 mm, rotating speed 1 mm/s.
