A study into effects of surface defects on the rolling contact fatigue of brass and rail steel has
been undertaken on a twin-disc rolling-sliding test machine with both oil and water …

Rolling/sliding contact fatigue tests were conducted using a pair of transparent discs
containing a hole or a surface crack produced artificially on the disc surface. The crack …

Progressive changes in the surface topography of the running track in a rolling contact
fatigue tester were studied by using replica techniques and the electron microscope. Early in …

A series of experiments describing the wear of steel rollers during lubricated pure rolling
contact are presented. A four-roller machine is used for the experiment; the velocity …

The influence of dissolved water in the lubricant on fatigue-failure location and surface
alteration was determined from experiments conducted with a planetary four-ball machine in …

Rolling/sliding contact fatigue tests were carried out on a two-disc machine. Transverse and
longitudinal furrows and conical and spherical dents were made on each specimen surface …

Unexpectedly high uniform rates of wear occur from time to time in concentrated lubricated
rolling contacts having low slide-roll ratios. Such wear can occur under quite mild conditions …

Lubricant formulations for manual gear box applications are optimized for gear contacts
although rolling element bearings are lubricated with the same fully formulated oil. This may …

The useful life of rolling elements is limited by surface disintegration, pits being formed by a
fatigue process. Controversy exists as to whether cracks initiating failure start under the …

Water dissolved in hydrocarbon lubricants reacts with dynamically stressed metal surfaces
lubricated by the hydrocarbon. Experiments to study this phenomenon have been conducted …
