revealed that superlubricity can be ''switched'' on and off in situ when an ionic liquid is used to lubricate the silica–graphite interface by atomic force microscopy measurements [13]. When the potential is changed, the composition of the interfacial layer responds, which alters the frequency ...
A process for producing a frictionally locking connection of two structural component parts, especially a shaft and a hub, including plastically deforming a round structural component part into an oval or polygonal shape by applying force, applying additional force to substantially elastically round the...
dark band. We have previously shown that a characteristic finger width emerges as a result of the force balance between the gas pressure on the inside of the finger and the capillary forces and friction at the interface. This characteristic width gives rise to the uniform wavelength of the laby...
Both the load and friction force sensors had a resolution of 0.01 N. The sliding stroke was 12.5 mm, and the reciprocating frequency ranged from 0.05 to 0.8 Hz, corresponding to the average sliding speed from 1.25 to 20 mm/s. The tests were carried out in a controlled laboratory ...
