Effects of lubrication on wear and rolling contact fatigue behavior of class B wheel steels against R350HT rail steels using a twin-disc wear simulator

Leso, Tshenolo Phinah; Siyasiya, Charles Witness; Mostert, R.J. (Roelf); Moema, Joseph (Taylor and Francis, 2023)

Wear and rolling contact fatigue (RCF) are major causes of delays and unavailability of rail systems. The presence of lubricants at the rail and wheel interface influences wear and RCF. Lubricants include naturally occurring ...
Effects of slip ratio on wear performance of class B wheel steels against softer R260 rail steels using the twin disc setup

Leso, Tshenolo Phinah; Siyasiya, Charles Witness; Mostert, Roelf Johannes; Moema, J. (Southern African Institute for Industrial Engineering, 2022-11-11)

A train experiences different slip ratios at the wheel/rail contact point as it moves along the rail track, which influences the rolling contact fatigue (RCF) and wear properties of wheel and rail materials. This variation ...
