Progress in Tribological Properties of Nano-Composite Hard Coatings under Water Lubrication
Lubricants, 2017 The tribological properties, under water-lubricated conditions, of three major nano-composite coatings, i.e., diamond-like carbon (DLC or a-C), amorphous carbon nitride (a-CNx) and transition metallic nitride-based (TiN-based, CrN-based), coatings are ...

Monitoring of lubricant film failure in a ball bearing using ultrasound [PDF]
, 2006 A lubricant-film monitoring system for a conventional deep groove ball bearing (type 6016, shaft diameter 80 mm, ball diameter 12.7 mm) is described. A high-firequency (50 MHz) ultrasonic transducer is mounted on the static outer raceway of the bearing ...

Tailoring the tribological properties of nanostructured carbon films under water lubrication
Friction, 2023 Carbon films have been considered suitable to be applied in water lubrication since they exhibit excellent friction-reducing and wear resistance, chemical inertness, etc.

Take-off of small Leidenfrost droplets [PDF]
, 2012 We put in evidence the unexpected behaviour of Leidenfrost droplets at the later stage of their evaporation. We predict and observe that, below a critical size $R_l$, the droplets spontaneously take-off due to the breakdown of the lubrication regime.

Friction and wear behaviour of 18 polymers in contact with steel in environments of air and water [PDF]
, 1991 18 polymers were characterized with respect to their friction and wear behaviour in contact with steel in environments of air and water. These were six unfilled materials, i.e. polyamide 66 (PA 66), polyoxymethylene (POM), polyethyleneterephthalate (PETP)
