Evaluation of stereometric properties of the surface layer of the examined material was performed based on the amplitude, height and Abbott-Firestone curve parametres. The shot peening was carried out on the impulse shot peening stand. The impact energy Ej, distance between the traces xs and the ball diameter dk were changed in the range: Ej = 60 ÷ 240 mJ, xs = 0,15 ÷ 0,5 mm, dk = 3,95 ÷ 12,45 mm. The T8000 RC 120-140 device of the Hommel-Etamic company, along with the software, was used for measuring the surface roughness and for determining the material bearing curve. As a result of the machin-ing, the surface roughness was reduced and the selected functional parameters were improved.
