Friction Reduction in Elastohydrodynamic Contacts by Thin-Layer Thermal Insulation

Tribology Letters, 2014
Reducing friction is of utmost importance to improve efficiency and lifetime of many products used in our daily lives. Thin hard coatings like diamond-like carbon (DLC) have been shown to reduce friction in full-film-lubricated contacts. In this work, it is shown that contrarily to common belief, the friction reduction stems mainly from a thermal ...

A Review on the Impact of Bio‐Additives on Tribological Behavior of Diesel Fuels

Advances in Tribology, Volume 2024, Issue 1, 2024.
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 parts to endure for less time, be less reliable, and require more maintenance. Diesel fuel can potentially be replaced with biodiesel among other fuels.
