[30] aimed to determine the influence of cooling and lubrication conditions in diamond burnishing on the surface integrity and fatigue limit of chromium-nickel austenitic stainless steels. Based on their findings, a cost-effective and sustainable diamond burnishing method was developed. They demonstrated that lubricant-free diamond burnishing meets the requirements of sustainable manufacturing and offers a favorable cost-to-quality ratio. Four lubrication/cooling variants were tested: one conventional flooded (non-dry) lubrication process and three dry burnishing techniques. The dry methods included: (a) dry burnishing without cooling; (b) dry burnishing with air cooling at \(-19\)\({}^{\circ}\)C; and (c) dry burnishing with nitrogen cooling at \(-31\)\({}^{\circ}\)C. The dry diamond burnishing techniques (a, b, and c) generated a high atomic density submicro-crystalline structure, with the strongest crystalline development occurring in method (a). Among the dry methods, option (a) also produced the highest microhardness in both the surface and the subsurface layers. In another study, [PERSON] et al. [31] established explicit correlations between surface integrity and fatigue limit in cold-worked chromium-nickel austenitic stainless steels. The cold-plastic deformation process was implemented by diamond burnishing of AISI 304 stainless steel. A simplified optimization approach was proposed to achieve the maximum fatigue limit without performing fatigue testing. Five surface roughness parameters were examined (R\({}_{\text{a}}\), R\({}_{\text{q}}\), R\({}_{\text{v}}\), R\({}_{\text{sk}}\), and R\({}_{\text{ku}}\)), each considered a functionally significant indicator of fatigue behavior, microhardness, and surface residual stress. The primary influencing factors were the burnishing force and the number of passes. The surface integrity and fatigue limit models were developed using design of experiments and regression analyses. The fatigue behavior and corrosion resistance of AISI 304 austenitic stainless steel are also affected by heat treatment and diamond burnishing [32]. The highest fatigue strength in that study was achieved via multipass diamond burnishing without subsequent heat treatment. However, the best corrosion resistance was attained when burnishing was followed by heat treatment. In the case of AISI 304 chromium-nickel stainless steels, conventional chemical-thermal surface treatments often present issues such as grain boundary corrosion, for which low-temperature surface treatments are a viable alternative. Surface cold working can enhance both the surface microhardness and fatigue strength. The main objective of study [33] was to determine the effect of diamond burnishing on the rotating fatigue strength of AISI 304L stainless steel. The influence of burnishing parameters on surface integrity characteristics was assessed, and optimal conditions were identified where the surface roughness was minimized and microhardness was maximized. Aluminum bronzes with the composition Cu-10 Al-5 Fe are widely used across various industries due to their high strength, wear resistance, and corrosion resistance, even in aggressive environments such as seawater. In study [34], hot-rolled Cu-10 Al-5 Fe bronze rods were subjected to various heat treatments, followed by diamond burnishing that induced significant surface plastic deformation. The effects of these processes on microstructure, surface integrity, mechanical properties, cyclic fatigue strength, and dry sliding wear resistance were investigated and quantitatively compared. Similar studies were performed on CuAl8 Fe3 bronze components [39] to evaluate the influence of heat treatment and significant surface plastic deformation. The effect of diamond burnishing on mechanical properties, fatigue life, and wear resistance was analyzed. In this case, surface integrity improvement could only be achieved through mechanical surface treatment.
