“…In the work carried out by Hua and Liu [37], they reported that increase of cutting nose radius yield better surface finish. It has been also confirmed by Shi et al [38] that increase of contact surface (as result of using roller strike) leads to improved surface quality. It is evident that the model could predict reduction of surface roughness by increase of ball diameter within acceptable error.…”

In mechanical based machining processes, the surface topography is generated through series of hierarchical pattern. Plastic deformation as result of contact and kinematic of motion are two main factors which determine evolution of surface generation. To basically optimize the surface quality, accurate predictive model of surface generation and constraints are required. In the present work, analytical models of dimple formation and hierarchical surface generation in ultrasonic assisted ball burnishing process are proposed. Pileup and sink-in as two phenomena of indentation during both of loading and unloading phases were taken into the developed models. Considering interaction of indentation profile and kinematic of motion, three-dimensional surface topography and surface roughness are also analytically predicted. A criterion for surface failure is defined to perform process without any erosion. Confirmation of results have been made by series of single trace and multitraces burnishing experiments on AA6061-T6 and AISI 1045. The results of indention profile, surface topography, roughness and failure criterion which were derived from predictive models were completely consistent with confirmatory experiments.

“…In recent years, many studies have been devoted to improving the surface integrity (SI) and operating behavior (wear, corrosion and fatigue resistance) of CNASS components by means of static SCW methods: ball burnishing [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], roller burnishing [6,[22][23][24][25] and DB [2][3][4][26][27][28][29][30][31][32][33][34][35]. There are relatively few studies devoted to improvement in the fatigue behavior of CNASS components by means of SCW [2][3][4][8][9][10][11][12][13]18,23].…”

Chromium–nickel austenitic stainless steels are widely used due to their high corrosion resistance, good weldability and deformability. To some extent, their application is limited by their mechanical characteristics. As a result of their austenitic structure, increasing the static and dynamic strength of the components can be achieved by surface cold work. Due to the tendency of these steels to undergo intercrystalline corrosion, another approach to improving their mechanical characteristics is the use of low-temperature thermo-chemical diffusion processes. This article proposes a new combined process based on sequentially applied diamond burnishing (DB) and low-temperature gas nitriding (LTGN) to optimally improve the fatigue strength of 304 steel. The essence of the proposed approach is to combine the advantages of the two processes (DB and LTGN) to create a zone of residual compressive stresses in the surface and subsurface layers—the enormous surface residual stresses (axial and hoop) introduced by LTGN, with the significant depth of the compressive zone characteristic of static surface cold working processes. DB (both smoothing and single-pass hardening), in combination with LTGN, achieves a fatigue limit of 600 MPa, an improvement of 36.4% compared to untreated specimens. Individually, smoothing DB, single-pass DB and LTGN achieve 540 MPa, 580 MPa and 580 MPa, respectively. It was found that as the degree of plastic deformation of the surface layer introduced by DB increases, the content of the S-phase in the nitrogen-rich layer formed by LTGN decreases, with a resultant increased content of the ε-phase and a new (also hard) phase: stabilized nitrogen-bearing martensite.

“…Their results indicated that a more uniform and smoother surface could be achieved at higher frequencies. 40 Zhen-Yu et al (2021) studied the effects of ultrasonic vibration directions (tangential and vertical) in UAB on the surface roughness of aluminum alloys. They reported lower surface roughness for tangential ultrasonic vibration.…”

“…Jerez-Mesa et al (2020) experimentally measured the surface topology of Udimet ® 720 after UAB. They recorded the best surface integrity improvement by five passes of UAB with a force of 450 N. 39 In another work, Shi et al (2020) analyzed the impacts of UAB tips and parameters on the surface integrity of austenitic stainless steel. Their results showed that a roller tip outperformed a ball tip in achieving desirable surface roughness.…”

Corrosion resistance of materials is predominately dependent on their surface roughness. Therefore, surface finishing techniques can effectively improve the corrosion resistance of the components. Ultrasonic-assisted burnishing (UAB) process is a newly developed surface finishing technique capable of flattening the surface of components without material removal. This research experimentally investigated the effects of amplitude in the UAB process on surface roughness and corrosion performance of AA7075-T6 aluminum alloys. Turned sample (control) was treated by conventional burnishing (CB), followed by UAB with an amplitude of 10, 20, and 30 µm. Then, the surface roughness, microstructure, microhardness, and corrosion resistance of the treated samples were assessed. The surface roughness showed an improvement upon burnishing of the samples, where the best surface was achieved by UAB with an amplitude of 10 µm. UAB process also led to grain refinement such that finer grains could be achieved by increasing the amplitude. Microhardness also increased after the UAB process which got intensified by increasing the amplitude. The turned sample showed the least corrosion resistance, while the UAB-treated specimens (amplitude of 10 µm) exhibited minimal corrosion rate. Furthermore, the enhancement of UAB amplitude increased the surface roughness, causing a decline in corrosion resistance.
