Ultrasonic burnishing induces beneficial compressive stresses and high surface quality in components with contact as a functional requirement. It was observed in previous work that some burnishing parameters can hinder burnishability of stainless steels. In this research tangential misalignment angles (TMA) for burnishing were varied considering as-supplied and heat-treated stainless steel. Properties such as surface hardness and surface roughness were measured after burnishing process. Electron Backscatter Diffraction was performed to characterize microstructure using Matlab (MTEX) to calculate average grain areas. By changing burnishing parameters, i.e., shaft rotational speed and burnishing tool diameter, it was observed that burnishing was less successful. Nevertheless, significant improvement in burnished surface quality was observed after heat-treatment process. In addition, grain size characterization revealed mean grain area reduction from 26 µm2 for unburnished to 11 µm2 and 3 µm2 for burnished and heat-treated samples respectively. Most importantly this work reveals the enhanced possibility of burnishing stainless steels after heat-treatment with varying tangential misalignment angles.

An Overview on the Effect of Severe Plastic Deformation on the Performance of Magnesium for Biomedical Applications

et al. 2023

There has been a great interest in evaluating the potential of severe plastic deformation (SPD) to improve the performance of magnesium for biological applications. However, different properties and trends, including some contradictions, have been reported. The present study critically reviews the structural features, mechanical properties, corrosion behavior and biological response of magnesium and its alloys processed by SPD, with an emphasis on equal-channel angular pressing (ECAP) and high-pressure torsion (HPT). The unique mechanism of grain refinement in magnesium processed via ECAP causes a large scatter in the final structure, and these microstructural differences can affect the properties and produce difficulties in establishing trends. However, the recent advances in ECAP processing and the increased availability of data from samples produced via HPT clarify that grain refinement can indeed improve the mechanical properties and corrosion resistance without compromising the biological response. It is shown that processing via SPD has great potential for improving the performance of magnesium for biological applications.

“…Recently, the importance of the roughness properties has been reported to achieve better results in terms of fatigue, 23 being the smoothest surfaces the optimal ones to enhance fatigue behavior. The ball‐burnishing process induces a microstructure deformation, or restructuration, based on a grain‐size refinement in a determined depth of affectation 14,24 . Typically, this depth is directly related to the compressive residual stresses and the increase of the hardness, deriving in a strengthening of the material 25,26 .…”

“…In particular, the burnishing process consists of a cold deformation in which the outer asperities are compressed against the surface, filling the material valleys and reaching a smoother surface and hardening due to this strengthening induced. In summary, the main advantages of burnishing are roughness smothering, 9,10 hardness increase, 11,12 corrosion resistance, [13][14][15] wear resistance, 16,17 and fatigue life enhancement 18,19 due to the effect of the compressive residual stresses. 20 Within the deforming processes, one of the most common and used is ball burnishing (BB).…”

This paper aims to present a study of the effects of ball burnishing with vibration assistance on the bending fatigue endurance of cylindrical specimens subjected to bending stress and obtain the best input parameters. The specimens were burnished through six different combinations of preload force, number of passes, and vibration assistance, finding that burnishing while applying a 90‐N preload, five passes, and the addition of vibration assistance results in larger fatigue strength. In terms of roughness, it has been proved that vibration‐assisted ball burnishing reduces the mean roughness up to 90%, while enhancing the skewness and kurtosis parameters. The softening effect while deforming, caused by the vibration assistance, helped to reconstruct the surface, obtaining higher depths of affectation and hardening. Fatigue strength was improved by a 6.54% by only adding vibration assistance to the ball‐burnishing process.
