Surface processing of titanium alloy Ti6Al4V samples with nanosecond laser pulses (λ = 1060 nm, τ = 120 ns) under a thin layer of water has been carried out. Changes in the surface topography and structural-phase state of the near-surface layers of the Ti6Al4V alloy are studied by scanning electron microscopy and X-ray diffraction analysis. It is shown that such treatment leads to a refinement of the structure of the surface layer and the formation of tensile residual macrostresses in the near-surface layers.
