" Rolling contact fatigue (RCF) is a pervasive and insidious problem on all types of railway
systems. Although it is a dominant cause of maintenance and replacements on heavy haul …

In recent years, with the continuous improvement of train carrying capacity and speed, more
strict requirements are put forward for the service performance of rail steel. Bainitic steel has …

Rolling contact wear is a complex phenomenon that might involve different wear
mechanisms (adhesive, abrasive, fatigue and corrosive) and different stress concentration …

Recent studies of the rail—wheel interface have shown that wear and rolling contact fatigue
(RCF) are competitive phenomena. Wear, by removing the material from the contact surface …

Twin disc tests were employed to assess rail grease formulation effect on friction, wear, and
retentivity to propose guidelines for grease selection based on key aspects of grease …

Subsurface microstructural alterations are formed in the later stages of rolling contact fatigue
(RCF) under high contact pressure. The subsurface changes observed as a dark contrast …

Simple n-alcohols, such as 1-dodecanol, show anomalous film-forming and friction
behaviors under elastohydrodynamic lubrication (EHL) conditions, as found inside bearings …

The application of coating gets exceptional importance since it improves the tribological
properties of the contacting surfaces. Different input parameters like coating deposition …

Rolling bearing elements develop structural changes during rolling contact fatigue (RCF)
along with the non-proportional stress histories, evolved residual stresses and extensive …

This research presents the results of the effect of different concentrations (2, 4, 6, and 8 wt%)
of multiwall carbon nanotubes (MWCNTs) and aluminum oxide nanoparticles (Al2O3) on the …
