“…The burnishing process is a surface plastic working technique that is known by researchers and scientists, but first of all research is carried out on single-layer materials [ 17 , 18 , 19 , 20 , 21 , 22 , 27 , 28 , 29 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ] and not for coated materials. Therefore, and based on our own research, an experimental analysis of the burnishing of products with the applied alloy and composite coatings was undertaken.…”

In the machine, metallurgical, and shipbuilding industries, steel products with alloy and composite coatings based on nickel may be used. It is expedient to improve the physicochemical properties of the surface layer of products as they have a significant roughness value after thermal spraying. It is therefore important to finish the layers applied by flame spraying, where machining is used for this purpose. However, it causes a loss of coating material, which is quite expensive. Therefore, in order to reduce costs and improve the quality of the surface layer, the finishing treatment of nickel-based coatings by means of plastic working is used. Two types of plastic working were proposed: rolling and burnishing. Numerical and experimental tests of the plastic processing of alloy coatings were carried out. The roughness of the coatings after rolling decreased to 1/25 and 30% strengthening of the alloy coating matrix was determined. After burnishing, roughness was reduced to 1/12 and the alloy coatings were strengthened by 25%. Plastic working by rolling and burnishing has a beneficial effect on the surface quality of the workpiece, not only by significantly improving the roughness, but also by increasing the strength properties of the surface layers.

“…The burnishing process does not produce chips or sparks, as in the case of using chip and abrasive machining. For this reason, burnishing is currently known as one of the ecological treatment methods [ 18 , 19 , 20 , 21 , 22 , 23 ].…”

“…The burnishing process is applied using different materials such as aluminum and its alloys (cast Al-Cu alloy, 7075 T6, AA2014, AA 7178, AA 7075, 6061--T6, Al 6061) [1,11,15,17,[18][19][20][21][22][23][24][25][26] and steel (plastic formwork steels, steel, heat-processed and tempered steel, hardened steel, AISI 5140, St37, X5CrNiMo17--12-2) [6,[27][28][29][30][31][32][33][34][35][36][37][38], polymers [39], brass [25,40], tita- nium [35], and copper [25]. An increase in the burnishing force has a positive impact on the surface roughness and hardness, and distortions may occur on the surface after specific values of the force.…”

5083 Al-Mg is the widely used material in food, chemistry, vehicle, machinery, and construction sectors, as well as in the aviation and space industries. The burnishing is normally used as the finishing operation for this material with the advantages such as surface roughness, reduced fracture formation, hardness, fatigue strength, and an increase of the wear resistance. These positive improvements are dependent on burnishing process parameters such as feed rate, burnishing force, ball diameter, and a number of revolutions. The study contains determination and optimization of the machining parameters and their effects on the surface roughness, microhardness, and the strength of 5083 Al-Mg material in the ball burnishing processes. Multiple regression and ANOVA analysis were performed to identify significant process parameters. A new Artificial Neural Networks (ANN) model with different neuron structures and algorithms has also been developed using experimental results to supplement the multiple regression model as the desired R 2 values could not be achieved with the latter. The ANOVA analysis indicated that both the burnishing force and the number of revolutions have a significant effect on the surface roughness and hardness with optimums 300 N and 200 rpm, respectively. Results from the two models were compared with each other. The developed ANN model is shown to estimate the surface roughness and the surface hardness with high reliability (R 2 = 0.999992) without costly experimental trials.

“…The burnishing process include: strengthening treatment -for which it is important to achieve the desired changes in the physical properties of the material, which among other reduce abrasive wear and increase hardness and fatigue strength; smoothing -which aims at reducing the roughness and roughness of the surface. Dimensional smoothing treatment -through which accurate dimensional accuracy is achieved, combined with obtaining of low surface roughness [14,15]. During planning of technological process of manufacturing or regenerating machine components, the method of burnishing, the machining conditions, the shape and number ISSN: 1231-4005 e-ISSN: 2354-0133 DOI: 10.2478/kones-2019-0030 of burners should be selected.…”

“…The selection of burnishing conditions is based on approximate calculations of forces and unitary pressures, experimental results of materials with similar properties, universal nomograms, and specialist norms [3,7,8,10,15]. For cases where there are insufficient certain dependencies and nomograms and for burnishing with simultaneous cutting, the selection of conditions should be made on the basis of preliminary tests [3][4][5][6][7][8][9][10][14][15][16]. The technological process resulting in low surface roughness should be realized with application of as much pressure as possible on the surface of the treated element, while the speed of the burnishing and the feed rate should be low.…”

Products used in the construction of machines and shipbuilding as well as petrochemical industry, such as shafts, bars, pipes and the like from two-phase stainless steel are currently very popular. It is required that they meet certain quality criteria. They must be characterized by suitable properties of the surface layer to meet the requirements of potential buyers. In the article impact of processing parameters on the degree of relative strain hardening and index of surface roughness reduction were presented. The burnishing process was carried out for two-phase stainless steel. Burnishing process of the shafts neck was performed using burnisher roller. The experimental research were obtained in the surface layer increase in hardness and the material ratio curve a convex shaped, which, taking into account the load capacity of the surface will be directly affected by its resistance to wear and corrosion. The experimental research by application of the burnishing process was made in the Laboratory of Production Engineering. After the studies it was found that the hardness of the surface layer and the roughness of the shaft necks an important influenced by technological parameters of processing (burnishing speed, feed rate and depth of burnishing). The objective of applying burnishing process may be, for example, the need to increase surface smoothness and dimensional accuracy of part.
