Automobile engines require lubrication to lessen the impact of friction due to the high levels
of wear and frictional heat generated by the sliding parts. Wear and friction will cause engine …

The study investigates tribofilm distribution and tribology performance on piston ring-cylinder
liner surfaces under realistic internal combustion (IC) engine conditions. By examining the …

Tribochemical reactions, chemical processes that occur by frictional shear at sliding
interfaces, lead to tribofilm formation or substrate wear that directly affect the efficiency of …

Low-rank coal is an important pathway to realizing the clean and efficient utilization of coal,
and promoting the energy conversion of low-rank coal using waste aligns with the current …

Lubrication is critical to achieve stable rolling during the cold rolling of flat steel products.
However, the oil film thickness distribution in the roll bite and its effect on the friction between …

The antiwear properties of tribofilms formed on steel surfaces lubricated with various multi-
component lubricants were investigated at an elevated temperature and under load-speed …

Modelling wear characteristics involving the fully formulated oil (FFO) with its tribochemistry
is challenging due to its complex chemical components. This paper developed a model to …

This study examines the wear characteristics of case-carburized steel surfaces with
manganese phosphate (MnPh) coating under commercial fully formulated oil (FFO). This …
