“…At the 2nd and 3rd levels of the burnishing force, there is a dramatic increase in average surface roughness value with the increase in the burnishing force, the burnishing tool applies a higher pressure to the workpiece surface, allowing it to penetrate deeper, thus increasing the material flow on the workpiece surface, Figure 8. As a result, the peaks and valleys on the workpiece surface are smoothed and the surface quality is increased [3, 26, 27]. On the other hand, when the number of passes are examined, the 1st and 2nd level of the pass number is above the mean in terms of average surface roughness, but average surface roughness values are below the mean at the 3rd level.…”

Roller burnishing method is a low-cost and effective surface treatment method that has been frequently preferred in recent years. In this method the surface roughness is minimized by small plastic deformations, without removing chips from the surfaces, caused by the rolling element pressed against the surface with a certain force. While the surface hardness of the material increases in the process, the surface roughness decreases significantly. In this study, the effects of the process parameters of roller burnishing method (burnishing pressure and number of passes) on AA7075-T6 aluminum alloy in terms of fatigue strength and surface roughness were investigated experimentally. Taguchi L9 experimental design method was used in the study, and the burnishing process was carried out by a specially produced disc-shaped apparatus. As a result of the study, it was determined that the roller burnishing method increased both the fatigue strength and surface quality of AA 7075 T6 alloy. In consequence of roller burnishing, it was determined that fatigue life and surface roughness values improved by 116 % and 96 %, respectively.

“…This is because in traditional experimental designs, especially many experiments have to be performed and it is difficult to apply when the number of processing parameters is increased. Therefore, the Taguchi experimental design method allows more than one factor to be taken into account at the same time, but also provides the optimum result with less experimentation [32][33][34][35][36]. The Taguchi method can reduce the number of experiments without concluding the results [37].…”

The superalloys are hard to machine materials used in critical applications such as aeronautics and aerospace sectors. One of the most important parameters of the machinability tests is the surface roughness values, which enable us to determine the specific properties of the material measured from the surface of the materials being machined. So, this study proposes to advance a depth understanding of surface roughness evolution, of Incoloy 825 material, when is submitted to machining process. The machinability of Incoloy 825 superalloys were investigated by varying different high-speed machining parameters. Three different cutting tools (I, II and III), three different speeds (500, 1000 and 2000 m/min) and three different feed rates (0.1, 0.2 and 0.4 mm/rev) were chosen as parameters. The surface quality, chip formation and tool wear outputs of the Incoloy 825 machined workpiece were analyzed and optimum machining parameters were determined. The results indicate that the key parameters impressing the surface roughness, of the Incoloy 825 superalloy, are the cutting speed and feed rate, respectively. Further, the cutting tools investigated have not had a material impact on the surface roughness. The accelerated tool wear is driven by the cutting speeds as well. An overview of the results achieved in this study indicate that the optimal surface roughness value is reached when the following parameters are imposed: tools type: II, cutting speed: 1000 m/min and feed: 0.1 mm/rev.

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.
