The porous expanded graphite (EG) was metallized by electroless plating to improve the C‒
Cu interface bonding, and the copper-plated EG/Cu (EG@ Cu/Cu) composites with different …

Current-carrying friction affects electrical contact systems like switches, motors, and slip
rings, which determines their performance and lifespan. Researchers have found that …

We report the current density effect in controlling current-carrying friction of amorphous
carbon (aC) film sliding against steel ball. The current density at the sliding interface was set …

Field investigations have demonstrated that the wear life of a carbon slider of a pantograph
in a high-speed train of the 250 km/h speed class is very short. In this study, several …

A simple and effective method is used to construct graphene coating on brass surface, and
the effect of electric currents on tribological performances are studied. Results show that …

Copper matrix composites reinforced with TiO 2 particles are promising materials widely
used as contact materials due to their excellent mechanical and physical properties such as …

For sliding electrical contacts a combination of satisfactory current transfer and good
tribological performance is desired. A complete tribo-electrical study is presented where a …

Copper/graphite composites and copper/graphite/Ti 2 SnC composites were fabricated
through the process of ball-milling, pressing and sintering. The effects of Ti 2 SnC as the …

The tribological performance of metro rigid overhead lines against pantograph sliders was
experimentally studied. The test parameters from actual metro lines were adopted. During …

The foam copper with the thickness of 15–30 μm, the porosity of 97% was fabricated by
electroless plating method. The graphite/copper composites were fabricated through the …
