Rolling element bearings are the most critical parts of any rotary mechanism. One of the
challenges in any bearing design is to minimize the friction and maximize life for a particular …

Abstract Two-dimensional (2D) materials have demonstrated unique friction and antiwear
properties unmatched by their bulk (3D) counterparts. A relatively new, large and quickly …

This paper exhibits an outline of the piston rings operational characteristics and
consequently, of their main functional challenges. The basic geometrical shapes, materials …

In automotive industry, most of the moving components and lubricants are currently being
reengineered in order to meet the much harsher operating conditions of electric vehicles …

In case of lightly loaded radial ball bearings, failure mechanisms other than fatigue such as
smearing of raceways due to increased frictional torque and vibrations often prevail. Hence …

Hydrogenated amorphous carbon (aC: H) film exhibits the superlubricity phenomena as
rubbed against dry sliding contacts. However, its antifriction stability strongly depends on the …

Boron doping of diamond-like carbon coatings has multiple effects on their tribological
properties. While boron typically reduces wear in cutting applications, some B-doped …

Rolling element bearings and gears are critical components of mechanical systems such as
wind turbines and automotive engines and transmissions that use oil-based lubricants. Oil …

In an effort to improve the surface properties of electrical contact materials in terms of high
friction coefficient and wear rate, diamond-like carbon (DLC) films containing different metal …
