Laser cladding could be applied on railway wheels to improve their service lives. Fe-based
alloy powder is widely used as the laser cladding material due to its good self-fluxing ability …

The wear and rolling contact fatigue of wheel-rail materials were investigated through
varying wheel/rail hardness ratios (H w/H r) and creepages. The results indicated that with …

Rolling-sliding wear experiments were performed to investigate the wear and rolling contact
fatigue (RCF) behaviours of a premium pearlitic rail (PH), a carbon-free bainitic rail (BH) and …

The objective of this study is to evaluate the effect of slip ratio on the wear and rolling contact
fatigue (RCF) of wheel/rail materials using a rolling–sliding wear testing apparatus. The …

Abstract Fe 3 O 4 nanospheres, MoS 2 nanospheres and Fe 3 O 4@ MoS 2 nanocomposites
were used as lubricating oil additives for steel/steel contact and dispersed in PAO4 base oil …

This study discusses a Tγ/A method of plotting wear data from a twin-disc machine for
identifying the wear and damage transitions of wheel and rail materials. As found in previous …

The wear map can directly reflect the wear state and mechanism of the friction pair under
different conditions and is widely used in wear prediction and fault diagnosis of steel …

This paper aimed to investigate the wear properties of different wheel-rail material pairs with
various hardness values. Twin-disc wear experiments were carried out via cross-matching …

This study aims to explore the wear and rolling contact fatigue (RCF) competition
mechanism of the hypoeutectoid, eutectoid rail, and bainitic rail steels under different slip …

The friction and abrasive wear behavior of WC-12Co and Cr 3 C 2–25NiCr HVOF sprayed
coatings were investigated. The coefficient of friction and abrasive wear rate decreased with …
