“…Two abrasives were used in this test: glass microspheres and walnut shells. On the one hand, glass microspheres were selected because this abrasive produces impact wear on the surface of the coating, leaving a spherical footprint equivalent to a soft burnishing [31] and, on the other hand, walnut shells were selected because the wear is of the shearing type and generates micro-cuts [32]. In short, we wanted to study the response of the coatings and their relationship with the substrates through interactions with different abrasion phenomena: impact and shearing.…”

This study compares subtractive manufacturing (SM) and additive manufacturing (AM) techniques in the production of stainless-steel parts with non-stick coatings. While subtractive manufacturing involves the machining of rolled products, additive manufacturing employs the FFF (fused filament fabrication) technique with metal filament and sintering. The applied non-stick coatings are commercially available and are manually sprayed with a spray gun, followed by a curing process. They are an FEP (fluorinated ethylene propylene)-based coating and a sol–gel ceramic coating. Key properties such as surface roughness, water droplet sliding angle, adhesion to the substrate and wear resistance were examined using abrasive blasting techniques. In the additive manufacturing process, a higher roughness of the samples was detected. In terms of sliding angle, variations were observed in the FEP-based coatings and no variations were observed in the ceramic coatings, with a slight increase for FEP in AM. In terms of adhesion to the substrate, the ceramic coatings applied in the additive process showed a superior behavior to that of subtractive manufacturing. On the other hand, FEP coatings showed comparable results for both techniques. In the wear resistance test, ceramic coatings outperformed FEP coatings for both techniques. In summary, additive manufacturing of non-stick coatings on stainless steel showed remarkable advantages in terms of roughness, adhesion and wear resistance compared to the conventional manufacturing approach. These results are of relevance in fields such as medicine, food industry, chemical industry and marine applications.

“…Burnishing can achieve a surface roughness similar to that achieved by grinding or polishing. Further, burnishing increases surface hardness and residual compressive stress in the surface layer, which can improve the tribological and anticorrosive properties and the fatigue strength and wear resistance of the treated components [33][34][35]. Unfortunately, for openings with variable cross-section or openings with curved axels it is not possible with any of the conventional methods of burnishing.…”

“…Only one study used glass microspheres instead of abrasives for flow machining. In that study, Korzynska et al [35] theoretically analyzed the process mechanism at the minimum and maximum sphere content in the paste and experimentally determined the influence of processing parameters on the state of the surface layer.…”

“…Eqs. ( 1) and (2) indicate that the material undergoes only elastic deformation if the left-side condition is not satisfied; this condition is satisfied in microsphere flow burnishing (MFB) [35]. Further, if the right-side condition is not satisfied, cutting can occur.…”

“…This effect is observed when the particle content of the paste is approximately 50% [29,35]. Piston forces were transmitted through particles in direct contact with the workpiece surface at a particle content close to the maximum; this effect was analyzed by Korzynska et al [35]. The particle was pressed onto the workpiece surface by applying Fn, which was determined using Eq.…”

This study presents a novel flow processing technique that uses glass microspheres instead of abrasives. The fundamentals of flow machining with glass microspheres, including microsphere flow burnishing (MFB) and the conditions necessary for cutting or plastic deformation of a surface to occur during MFB, are determined. Details on such conditions are lacking, and therefore, this study attempts to define these conditions. To this end, MFB was experimentally confirmed to be a burnishing process, and the effects of MFB and abrasive flow machining (AFM) on 2017A aluminum alloy were compared. Both processes achieved a surface roughness (Sa) of < 0.5 μm, while MFB yielded higher values of surface microhardness and compressive stress. The effects of basic process parameters on the MFB and AFM results (workpiece weight loss and Sa) were compared experimentally and the corresponding mathematical models were established. Utilizing these relationships, MFB parameters can be selected so as to obtain the most favorable surface layer for the expected operating conditions.
