Extreme pressure (EP) and antiwear (AW) additives are necessary for boundary lubrication.
However, their mechanisms and physical and chemical properties remain unclear. EP and …

Friction and wear are ubiquitous, from nano-electro-mechanical systems in biomedicine to
large-scale integrated electric propulsion in aircraft carriers. Applications of nanomaterials …

Nickel-based Inconel 625 is employed in critical applications because of its excellent
properties. But the machinability of this material is very poor. In recent years, the use of …

A lubricant is derived from mineral oils or synthetic hydrocarbon blends. However, in order to
fulfill the requirements set by the Original Equipment Manufacturers (OEMs), they lack …

The need for energy efficiency is leading to the growing use of additives that reduce friction
in thin film boundary and mixed lubrication conditions. Several classes of such friction …

The term biolubricant applies to all lubricants that are easily biodegradable and non-toxic to
humans and the environment. The uses of biolubricant are still very limited when compared …

Energy and material conservation is an important global issue. In conventional practice,
lubricants were selected based on cost, performance, and life, and concern was not given to …

Water-based lubricants (WBLs) have been at the forefront of recent research, due to the
abundant availability of water at a low cost. However, in metallic tribo-systems, WBLs often …

This study investigated the effects of eco-friendly cutting conditions on machining
performance in the milling of Inconel X-750 superalloy. To this purpose, a total of 14 different …

Experiments were conducted using bio-based liquid lubricants, such as avocado, canola
(rapeseed), corn, olive, peanut, safflower, sesame, and vegetable (soybean) oils to study …
