“…The micro-cracking in these tests may be the start of the low cycle fatigue process that is sensitive to areas of coating inhomogeneity. Santner and co-workers have described geometric changes in friction where sliding probes encounter topographic features [56][57][58][59].…”

“…These authors observed sharp increases in friction sliding up steps and similar reduction sliding down steps. Adhesion was ruled out as the explanation since the effect was present in oil and in air [57], although triboreaction layers and wear particles could obscure the topographical effects [59].…”

“…Solutions, which are already in use in practice, are mainly the result of extensive experimental testing and hunting for optimal solution for a given application. However, in recent years, a lot of work has been presented [23][24][25][26][27][28][29] to try to design surface texturing based on 3D roughness parameters, essentially skewness (S sk ) and kurtosis (S ku ).…”

The aim of the present research work was to investigate the effectiveness of grooved surface texturing with a rhombic geometry under different lubrication regimes. Tribological investigation under unidirectional sliding was focused on the effect of texturing parameters including pattern area density on the coefficient of friction under different lubrication regimes, achieved by varying sliding speed and lubricant viscosity. Grooved patterns with different textured area densities were produced on steel samples by electrical discharge machining. Results of this investigation showed that under boundary lubrication, textures resist sliding thus resulting in increased friction. The largest improvement of friction reduction was observed under hydrodynamic lubrication, for low‐viscosity oil when using the textured disc with 21% pattern area density. The reduction of the coefficient of friction if compared with the untextured surface was of approximately 24%. Examination of the sliding surfaces has not shown any quantifiable wear for the contact conditions studied.

This paper describes the results of microtribology sliding experiments that were carried out on a range of micropatterned silicon surfaces. The objective of this work was to identify critical pattern features that control friction and fluid interaction on surfaces under a broad range of contact conditions and develop models to explain these relationships. These scratch tests were carried out in air, and with deionised water. Tests were carried out under a range of test loads and speeds, from low to high. It was found that in the dry tests, the measured friction was higher on the patterned surfaces than on the non-patterned surface. For the liquid experiments, there was a reduction in friction in some cases, dependent on the pattern and conditions used, indicating that the liquid acted as a lubricant. The greatest reduction in friction was obtained with a herringbone pattern aligned perpendicular to the direction of travel of the probe. However, for higher load conditions, high friction coefficients were measured for many of the patterns. The surfaces of the tested silicon samples were examined with optical microscopy and in high resolution scanning electron microscopy so that the interactions between the probe and the sample could be determined. It was found that the high friction values that had been observed in many experiments were correlated with considerable damage to the structure of the patterned silicon surface
