Graphene and MoS 2 were dispersed in esterified bio-oil (EBO) and evaluated as lubricants
for steel/steel contact. The tribological behaviors of steel/steel pairs were investigated under …

Sometimes, railway wheels cannot be re-turned and have to be discarded far before its time
in service due to local defects and severe wear. Laser cladding which deposits a surface …

Rail transportation is regarded as a reliable, quick, and secure mode of transportation. The
wheel-rail contact interaction is crucial to the railway operation since it is responsible for …

The tiny contact zone (approximately 1 cm2) where steel wheel meets steel rail is
fundamental to rail transport. This work is a comprehensive presentation of recent research …

A wheel/rail system is an open system, where the operating environment factors, such as
atmospheric humidity, temperature, and oxidation behavior, are subject to change. This …

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 …

Autumn leaves often cause low adhesion problems for train operations, leading to station
overruns and signals passed at danger (SPADS). The aim of this paper was to review …

The effects of low temperature on the adhesion coefficient under both dry and degraded
adhesion conditions are investigated using a rolling-sliding apparatus. The results indicate …

Wheel-rail interfaces operating in open systems are constantly affected by environmental
factors, such as water, relative humidity, temperature, leaves, and sand. In this study, a twin …

Most freight wagons in the EU use cast iron brake blocks. Cast iron brake blocks have a
stable braking capability in different environmental conditions, but wear down the wheel …
