Abrasive wear is a common failure mode of rolling bearings. To enhance the resistance of
traditional all-steel bearings to abrasive wear, the structure of traditional all-steel cylindrical …

Abstract Oil-in-water (O/W) emulsions are water-based lubricants and used as fire-resistant
hydraulic fluids and metalworking fluids (MWFs) in industry. The (elasto-) hydrodynamic film …

The surface textures of non-contacting mechanical seals form a few micrometers thick
lubrication film that aids in achieving high performance of the seal. Improved texture design …

With the increasing demand for active friction control, we newly proposed to use
dielectrophoresis to change the flow of PG-dropletcontaining PAO4 to reduce the friction …

Over the last years, aero-engines are progressively evolving toward design concepts that
permit improvements in terms of engine safety, fuel economy, and pollutant emissions. With …

Embedded particles in rolling/sliding contacting surfaces like gears and rolling bearings are
common. They come from either external contamination sources or final manufacturing …

When the lubricating oil flowing between the contact surfaces contains simulated wear
particles, it is considered that there is a high possibility for the particles to enter between the …

Observing wear debris during friction is crucial for comprehending the wear behavior of
lubrication systems. Despite various techniques attempted for observation, a persistent …

This paper focuses on the study of thickener behaviour in elastohydrodynamic contacts
using fluorescence microscopy and optical interferometry. A standard Ball-on-disc …

The development of microfabrication and surface machining techniques has made solid
surfaces more precise, and the gap dimensions in mechanical systems such as Micro …
