Evaluating Some Functional Properties of Surfaces with Partially Regular Microreliefs Formed by Ball-Burnishing

Volodymyr Dzyura et al.

Summary: In this study, the functional properties of three different types of regular microreliefs formed by ball burnishing process on flat surfaces were evaluated. The international standard ISO 21920-2:2021 was used to estimate the heights and material ratio curves criteria. The influence of regular relief type and ball burnishing process parameters on surface functional properties were investigated using a full factors experimental design. Statistical models were derived to describe the dependencies between topography characteristics, regular relief types, and regime parameters of the ball burnishing process based on the obtained results. Several conclusions have been formulated regarding the applicability of standardized methods and criteria for evaluating the functional characteristics of different types of regular reliefs at the end of the work.

Friction-induced rapid amorphization in a wear-resistant (CoCrNi)(88)Mo-12 dual-phase medium-entropy alloy at cryogenic temperature

Yue Ren et al.

Summary: The (CoCrNi)88Mo12 dual-phase MEA is fabricated to enhance the matrix and achieve excellent cryogenic wear performance. The study reveals that a significant wear reduction of 73% is achieved as the temperature decreases from 233 K to 113 K, and the friction-induced amorphous layer underneath the worn surface plays a crucial role in the excellent wear behavior at 113 K. The low stacking fault energy of the CoCrNi-rich matrix at cryogenic temperature and the high solute concentration of Mo contribute to the rapid amorphization process.

The Modelling of Surface Roughness after the Ball Burnishing Process with a High-Stiffness Tool by Using Regression Analysis, Artificial Neural Networks, and Support Vector Regression

Zeljko Kanovic et al.

Summary: This research investigated ball burnishing of AISI 4130 alloy steel with high-stiffness tool and ceramic ball, modeling and predicting surface roughness during the process. The regression analysis model showed large prediction errors at low roughness values but was reliable for higher roughness values, while artificial neural network and support vector regression models exhibited excellent predictability across different input variables.

Parametric description of one-process surface texture

Pawel Pawlus et al.

Summary: There is a problem with selecting areal parameters to describe surface texture, and analyzing the linear correlation between parameters can help in this selection process. By measuring and analyzing surface topographies after various machining treatments, sets of parameters that describe different surface groups were determined. It was found that specific parameters can be used to identify the machining process, and certain pairs of parameters better characterize the distribution of surface texture.

The Effect of Ball Burnishing on Dry Fretting

Slawomir Swirad et al.

Summary: Experiments were conducted under a dry gross fretting regime with steel discs in contact with ceramic balls. Ball burnishing led to a decrease in surface amplitude, an increase in microhardness, and up to 45% reduction in friction force and volumetric wear compared to sliding pairs containing milled discs. Higher roughness of the disc resulted in higher friction force and volumetric wear.

Effect of ball burnishing process on mechanical properties and impact behavior of S355JR steel

Mounira Bourebia et al.

Summary: The objective of the experiment was to evaluate the surface hardness, rupture strength, energy absorbed during impact testing, and work-hardened thickness of S355 JR steel specimens subjected to ball burnishing as well as quenching and tempering. The results showed that an increase in pressure force and number of tool passes can improve rupture strength and surface hardness, with the former increasing by 30.8% and the latter by 30.46%.
