## 1 Introduction
There are multiple deforming elements and techniques used in the static methods: (1) a roller or sphere, where the contact with the treated surface is rolling friction; (2) spherical or cylindrical, in which the contact with the treated surface is sliding friction; (3) a sphere whose contact with the surface being treated may be rolling friction at some times and sliding friction at other times; (4) a roller whose contact with the processed surface in the relative movement of the roller relative to the workpiece is sliding friction [6]. The strain-hardening capability of chromium-nickel austenitic SS makes it possible to increase the surface micro-hardness and strength by dynamic and static SCW. Nanostructuring of an AISI 316L SS specimen was achieved by [PERSON] et al. [7] via SMAT, increasing the yield limit to 1450 MPa. Using SMAT, [PERSON] et al. [8] achieved an unusual combination of strength and ductility in additively manufactured 316L SS. [PERSON] et al. [9] significantly increased the surface micro-hardness of 304L SS using appropriate SMAT process parameters. [PERSON] et al. [10] reported a 30% increase in the fatigue life of 304L SS due to SMAT processing. [PERSON] et al. [11] subjected 316L SS to shot peening and reported an increase in the fatigue resistance, surface micro-hardness, and resistance to pitting after increasing the shot peening time. [PERSON] et al. [12] improved the fatigue crack growth resistance and surface micro-hardness of AISI 304 SS via shot peening using different Almen intensities. [PERSON] et al. [13] established greater high-cycle fatigue strength in AISI 304 SS specimens subjected to ultrasonic shot peening compared to untreated specimens. The static SCW process is suitable for rotary surfaces and has the following advantages: (1) significantly improves SI (i.e., low values of the roughness height parameters, favourable values of roughness shape parameters in boundary sliding friction condition, high micro-hardness, and significant residual compressive stresses) while the core of the component remains tough; (2) the process is relatively economical due to low spare part consumption, and the process saves time, money, and energy; (3) tools have a long life and no technical operating skills are required; (4) the machining time is short. [PERSON] and [PERSON] [14] implemented Ecoroll's deep rolling process using a hydrostatic ball to increase the fatigue strength of AISI 304 SS. They achieve an increase in the fatigue strength of approximately 18% after \(10^{6}\) cycles--from 280 to 330 MPa. The low-cycle fatigue strength of AISI 304 SS was increased by [PERSON] et al. [15] via deep rolling. Using single-pass diamond burnishing (DB), [PERSON] et al. [16] increased the fatigue limit of AISI 316 Ti SS by 29.6% after \(10^{7}\) cycles, from 270 to 350 MPa. Applying four-pass DB, the increase reached 38.9% from 270 to 375 MPa. [PERSON] et al. [17] reported an increased fatigue limit of 38% in AISI 304 SS by DB compared to untreated specimens. Therefore, DB is an excellent option to increase the fatigue strength of austenitic SS axisymmetric components, and is cheaper and faster compared to dynamic MST. Moreover, chromium-nickel austenitic SS that is strain hardened by cold working can undergo further increases in strength if it is operated at a temperature of 300-400 \({}^{\circ}\)C, because the carbides are released in a dispersed form [1]. However, many studies reported that SPD introduced via dynamic SCW and, in particular, SMAT, has a detrimental effect on SS corrosion resistance. Using potentiodynamic polarisation curves and potentiostatic critical pitting temperature measurements, [PERSON] et al. [18] investigated the effects of SMAT and the subsequent annealing process on the corrosion behaviour of AISI 316 SS. They observed deterioration of the corrosion resistance after SMAT as a result of many cracks on the surface, but after annealing, the corrosion resistance of the nanostructured surface was recovered.
