“…Ultrasound shot peening (USP) rebuilds the geometry structure of nickel alloys. Machining traces are "punched" on the surface, which depth and amount on the surface depends on the material, of which the balls are made, the processing time and the impact energy [19]. The use of too much pressure during the machining of Inconel 718 nickel alloy results in an increase in surface roughness, which is due to the insufficient ability to absorb the deformation by the machined surface [14,21].…”

This article presents the research results of roughness and topography of the surface of Inconel 718 nickel alloy after shot peening. The evaluation of stereometric properties of the surface layer of the examined material was performed based on the amplitude, height and Abbott-Firestone curve parameters. The shot peening was carried out on the impulse shot peening stand. The impact energy E z , distance between the traces x s and the ball diameter d k were changed in the range: E z = 60 ÷ 240 mJ, x s = 0,15 ÷ 0,5 mm, d k = 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 machining, the surface roughness was reduced and the selected functional parameters were improved.

“…In recent years, surface treatments such as shot peening, ultrasonic peening, hammer peening, laser shock peening and roller peening [12][13][14][15][16] have been widely used for improving the mechanical properties, fatigue life and corrosion fatigue resistance by introducing a compressive residual stress layer in the near surface region through the work hardening from the surface treatments [17][18][19][20]. In the mean time, the surface modifications, in terms of surface roughness, surface morphology, surface passive/oxide film, near surface microstructure and residual stress induced by surface finishing processes, can affect the corrosion properties, especially pitting corrosion which is usually considered to be a precursor to stress corrosion cracking and corrosion fatigue crack initiation in chloride solutions [21][22][23][24].…”

“…The surface roughness after shot peening is dependent on the degree of coverage, the diameter of the peening balls, the type of material, from which the balls are made, the treatment duration and the impact energy [1,2,7,13].…”

The paper presents the research results of roughness and surface topography of the C45 non-alloy steel after centrifugal burnishing and perpendicular peening. The assessment of the geometric structure of the tested steel surface included the parameters: amplitude: Ra, horizontal: RSm, height: Rz, Rp and Rv, and Abbott-Firestone curve: Rpk, Rk and Rvk. Perpendicular shot peening was performed on a special position, while centrifugal burnishing on a 3-axis milling centre XH712G. The variable parameters during shot peening included the impact energy E z = 40 ÷ 220 mJ and the distance between traces x s = 0,15 ÷ 0,5 mm. The machining conditions of centrifugal burnishing were selected in such a way that the perpendicular component of the impact energy, longitudinal feed and transverse travel correspond to the variable parameters of perpendicular shot peening. The T800 RC 120-140 device of the Hommel-Etamic company with software was used for measuring surface roughness and topography.
