TLDR
In this paper, the deformation and wear of a roller bearing were analyzed using multi-level approach, i.e. at macro-level, from the perspective of the mechanics of a deformable rigid body, at meso-level II, implementing tribological approaches, and at mesoe-level I, using the methods of indentation, three-dimensional profilometry and fractography.About:

Capillary forces as a limiting factor for sawing of ultrathin silicon wafers by diamond multi-wire saw
Birgit Ryningen,Pål Tetlie,Sverre Gullikstad Johnsen,Sverre Gullikstad Johnsen,Halvor Dalaker +4 more
TL;DR: In this article, the authors suggest that the physical explanation to the observed limitations to ultrathin wafer sawing, by diamond multi-wire saw, is related to the capillary force acting on the wires due to the sawing liquid bridge connecting the wires.

A descriptive model of wear evolution in rolling bearings
Idriss El-Thalji,Erkki Jantunen +1 more
TL;DR: In this article, the authors propose a descriptive model of the wear evolution process in rolling bearings over the whole lifetime, which uses a wide range of empirical findings in the literature to describe the wear interactions and evolution in the five-stage scenario: running-in, steadystate, defect initiation, defect propagation, and damage growth.

Wear as a product failure mechanism – Overview and case studies
Colin Gagg,Peter Rhys Lewis +1 more
TL;DR: In this article, a brief review of salient points relating to wear as a product failure mechanism is presented and illustrated by numerous studies from the authors' forensic casebooks, as well as a brief discussion of wear processes at play during the service lifetime of a system, device or component.

Generation of shear bands in subsurface layers of metals in sliding
S. Yu. Tarasov,A. V. Kolubaev +1 more
TL;DR: In this paper, the formation of a nanocrystalline material on the surface due to shear instability is considered by analogy with formation of the shear band, which is responsible for the crossover from mild wear to the adhesive wear in the absence of mechanisms providing structural adaptability.

Torque loss in thrust ball bearings lubricated with wind turbine gear oils at constant temperature
TL;DR: In this article, six fully formulated wind turbine gear oils with the same viscosity grade and different formulations were selected and their physical properties were determined and tested on a modified four-ball machine at a constant temperature of 80°C under the following operating conditions: speed between 75 and 1200 rpm and two loads (700 n and 7000 n).

Processing and modeling of ordered relief at the surface of heat-resistant steels after laser irradiation as a cyclic random process
TL;DR: An approach to the mathematical analysis of ordered relief arising on the surface of heat-resistant steel 15Kh13MF after laser shock-wave treatment allowing one to obtain the quantitative and qualitative evaluation of the roughness parameters while taking into account the stochastic and the cyclical nature of the process is described.
