A Review of Low‐Plasticity Burnishing and Its Applications

Abstract

Low‐plasticity burnishing (LPB) has been widely used in various industries. In the LPB process, when the ball moves on the material surface, plastic deformation or cold working occurs in the burnished region. Through this process, not only can LPB improve the surface integrity of metallic material components by replacing polishing in some situations, but it can also improve fatigue performance thanks to the low work hardening and the beneficial compressive residual stress (CRS). So far, extensive research has demonstrated the influence of the LPB process on surface integrity and service performance of different metallic materials, such as titanium alloys, aluminum alloys, magnesium alloys, nickel‐based superalloys, stainless steels, and carbon steels. Recent years have witnessed many innovative LPB processes and novel applications. Herein, the working principle of the LPB process is first restated. Following that, how LPB strengthens the material surface and thereby influences the mechanical performance, including the surface quality, residual stress, microstructure, microhardness, fatigue, and wear performance, is reviewed. Furthermore, the difference of surface‐strengthening effect among LPB and other surface mechanical strengthening processes is compared. Finally, the current challenges to LPB are discussed and some suggestions on its development directions are put forward.

Enhancing the tribological properties of pure Ti by pinless friction surface stirring

“…Severe plastic deformation techniques such as equal channel angular pressing (ECAP), multi-directional forging (MDF), accumulative roll bonding (ARB), high pressure torsion (HPT), and thermomechanical processes such as hot rolling (HR) and hot extrusion (HE) have the great potential to improve the (bulk) mechanical properties of materials [5]. There are also SPD processes such as ultrasonic peening, burnishing, ultrasonic nanocrystalline surface modification (UNSM), and surface mechanical attrition treatment (SMAT) [6,7] that only change the surface structure and properties of the material at their surface regions. However, these techniques usually require special/expensive equipment and have limitations regarding the shape and dimensions of the sample.…”

Surface Characterization of Carbon Steel after Rolling Burnishing Treatment

“…Burnishing is one of the methods of finishing metals and their alloys, sinters and plastics, which involves the use of local plastic deformation [1][2][3], generated in the surface layer of the object [4][5][6][7][8][9], as a result of specific (force and kinematic) interaction of hard and a smooth tool (in the shape of a ball, disc, roller or other) with a machined surface [10][11][12][13][14][15][16][17][18]. The surface state and quality after previous treatment significantly depend on its quality after previous treatment [15][16][17][18][19].…”

“…The literature review shows that there are many works in the field of burnishing treatment. In the paper [1,2], low-plasticity burnishing and its applications were analyzed and the information on how low-plasticity burnishing strengthens the material surface and thereby influences the mechanical performance, including the surface quality, residual stress, microstructure, microhardness, fatigue and wear performance, are presented.…”
