“…Simultaneously with time reduction of shot peening, the depth of the enhanced zone is smaller. e research [18] concludes that sorbitic steels have the least capacity to strengthening by deformation of super cial (15% strengthening). is is related, among others, with lower susceptibility of ne-grained steel structures (sorbitic steel) to cold plastic deformation.…”

Here, the e ect of adhesion of CrN hard coatings on modi ed 42CrMo4 steel substrate is presented. Modi cations of the substrate are shot peening, nitriding, shot peening, and nitriding joined process. In the shot peening process, two variable process parameters were used: exposure time (t) and air pressure (p). e nitriding process was conducted in the following parameters: nitriding potential N p � 4.86, nitriding time t n � 3 h, and temperature process T � 530°C. Modi ed substrates were characterized by surface hardness HV5 and hardness pro les on the cross section of samples and by surface roughness parameters. On such prepared substrates, the CrN coating was deposited. e adhesion of CrN coating on modi ed substrates was de ned by the scratch test. Chemical and phase composition of the lms was determined using EDS method and X-ray di raction, respectively. e surface hardness of deposited lms was also de ned. e substrate of 42CrMo4 steel without mechanical and heat treatment coated by hard CrN lm was used as a reference.

“…The burnishing process is a surface finishing method of the plastic deformation of the surface in order to obtain high accuracy and small surface roughness parameter (Ra = 0.08 µm) [ 1 ]. In this process there is no removal of material from the surface and no significant consumption of tools and auxiliary materials, and so therefore the process is environmentally friendly.…”

During the low plasticity burnishing process of soft materials such as carbon steel with a hardness of up to 40 HRC (Rockwell grade) a raised structure of the material known as the Jumping Wave forms in front of the tool roll. This phenomenon significantly disturbs the burnishing process, but is very poorly described in the literature. This article presents studies of this phenomenon on the example of burnished 1.0562 steel. The research concerns the changes in the surface structure of the processed material as well as changes in the structure of the material during this process. The research shows changes in the geometric structure of the surface made in the 3D system and their parametric description. Moreover, the work presents an analysis of the metallographic structure in the tool zone. The research showed occurrence of material slippages in the wave in front of the tool, which creates an additional structure on the surface. These tests make it possible to better understand the process of changes that take place in the surface layer of the processed element in the low plasticity burnishing process.

“…A novel sequential process incorporating the hard turning with low plasticity burnishing was developed to enhance the surface integrity and corrosion resistance of Cr-Ni alloys [16]; and the authors stated that the CS and surface finish have important roles in improving the corrosion resistance; and the integrative process could be applied to produce anti-corrosion components. Hua et al (2019) developed a hybrid operation comprising the finish turning and low plasticity burnishing to improve the surface integrity and fatigue characteristic of Inconel 718 [17]; the results showed that (1) the surface characteristics, including the topography, phase change, MH, CS, and SR were significantly improved, (2) the fatigue life can be enhanced by 82.4% with the aid of a hybrid approach, and (3) the fatigue life was primarily affected on the CS and SR. An integrative operation using the turning and roller burnishing was developed to machine the long shafts [18], in which the mathematical model of the SR was developed in terms of the slenderness of shaft (SS), burnishing force (BF), f, and S; and the results showed that (1) the f is the most effective parameter, followed by the BF, SS, and S, respectively; and (2) the hardness, residual stress, wear resistance, and fatigue strength of machined components were improved with the support of the proposed process.…”

The burnishing process is used to enhance the machining quality via improving the surface finish, surface hardness, wear-resistance, fatigue, and corrosion resistance, and it is mostly used in aerospace, biomedical, and automotive industries to improve reliability and performance of the component. The combined turning and burnishing process is therefore considered as an effective solution to enhance both machining quality and productivity. However, the trade-off analysis between energy consumption, surface characteristics, and production costs has not been well-addressed and investigated. This study presents an optimization of the compressed air assisted-turning-burnishing (CATB) process for aluminum alloy 6061, aimed to decrease the energy consumption as well as surface roughness and to enhance the Vicker hardness of the machined surface. The machining parameters for consideration include the machining speed, feed rate, depth of cut, burnishing force, and the ball diameter. The improved Kriging models were used to construct the relations between machining parameters and the technological response characteristics of the machined surface. The optimal machining parameters were obtained utilizing the desirability approach. The energy based-cost model was developed to assess the effectiveness of the proposed CATB process. The findings showed that the selected optimal outcomes of the depth of cut, burnishing force, diameter, feed rate, and machining speed are 0.66 mm, 196.3 N, 8.0 mm, 0.112 mm/rev, and 110.0 m/min, respectively. The energy consumption and surface roughness are decreased by 20.15% and 65.38%, respectively, while the surface hardness is improved by 30.05%. The production cost is decreased by 17.19% at the optimal solution. Finally, the proposed CATB process shows a great potential to replace the traditional techniques which are used to machine non-ferrous metals.
