“…This last technique, consists by mean of a vibrating sole in propelling balls that hit the sample surface with different incident angles. With the goal of improving the mechanical properties of the surface, the later treatments have been applied on Cu [12], Mg [13,14], Al alloys [15],steels [16][17][18][19][20] and Ti [21,22] to introduce a deformation gradient at the top surface.…”

“…The deformation behavior of commercially pure titanium after SMAT has been described by Zhu et al [21]. Tribological properties of nanostructured alloys obtained by severe plastic deformation have been tested on steels [17], Ti [22,23], Al and Al 2 O 3 composites [24] as well as Mg [13,14]. However, no general trends could be worked out to explain the wear resistance reported for alloys treated by SMAT [13,14,17].…”

“…Indeed, some results were apparently contradicting for both steels and Mg alloys. For example, though the SMAT and friction conditions were highly similar, some authors noted a reduction in wear loss for the AZ31 Mg alloy [13] whereas for the Mg-6Gd-3Y-0.5Zr authors observed an increase in wear loss [14]. On steels, Sun [17] has explained some incoherences by taking into account the high severity of unlubricated contact and the hardening already sustained by the samples treated by SMAT.…”

The analysis of the tribological behavior of a steel ball on pure titanium has been carried out under alternative motion on both, a coarse grained Ti surface and its nanostructured derivative obtained by surface mechanical attrition treatment (SMAT). Along the duration of the tribology test, variations in friction behavior were interpreted as a three stages sequence of different wear mechanisms that were controlled by the successive formation of Ti-rich and Fe-rich oxides. Surface nanostructures appeared to change the oxide formation kinetics and delay the formation of a protective Fe-rich third body oxide layer on Ti. The results indicate that apparently contradicting literature results can be explained by taking into account the contamination induced during the SMAT process.

“…In this work, surface mechanical attrition treatment (SMAT) was chosen as a post-treatment performed on a Ni-Cr thermally sprayed coating. SMAT is actually a mechanical surface treatment derived from shot peening which can enhance corrosion resistance [36][37][38], tensile [39,40], fatigue [41,42], or tribological properties [43][44][45]. Tchana Nkonta et al [38] studied the influence of SMAT on the corrosion behavior of a Co-Cr-Mo alloy through potentiodynamic measurements and electrochemical impedance spectroscopy.…”

This study focuses on the effects of a surface mechanical attrition treatment on the structural and mechanical behavior of arc-sprayed Ni–Cr coatings deposited on steel substrates. The surface of the as-sprayed and SMATed coatings was characterized by X-ray diffraction, Scanning Electron Microscopy, and non-contact profilometry. The coating porosity was evaluated by using image analysis software. The residual stresses were determined using X-ray diffraction with the sin2ψ. Indentation tests were carried out on the cross sections of the different coatings to evaluate their hardness. The wear properties of the coatings were assessed using a pin-on-disk tester at ambient temperature without lubrication. The results showed that surface mechanical attrition treatment (SMAT) induced a grain refinement on the coating surface due to severe plastic deformation, which was associated with a significant improvement of the mechanical properties.
