“…The evolution of mechanical properties and microstructures of tribologically transformed structure (TTS) layers during fretting process were investigated using nanoindentation and focused ion beam-scanning electron microscope (FIB-SEM). A modified wear model that accounts for friction-induced dynamic changes in mechanical properties was proposed [206]. In Ref.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

Electrical connectors for motor vehicles are essential for the safe and efficient operation of a vehicle. However, their durability is limited by fretting induced corrosion. This type of surface damage is observed between two interconnected surfaces exposed to vibration and temperature variations. Such conditions occur during normal vehicle operation and cause two parts of an electrical contact to move at high frequency and with a small amplitude of movement relative to each other. This damages both surfaces, creates wear particles and then oxidizes them in the air. This causes an oxide layer to form at the interface, isolating the two surfaces and increasing the electrical resistance, resulting in contact failure. This study shows how the service life of electrical contacts can be extended by a surface design approach that controls the metal interface and ensures low contact resistance. The approach combines surface morphology with the progressive process of interfacial oxidation. A strong relationship between surface roughness and electrical contact resistance was observed and is elucidated in this study. Theory of Inventive Problems Solving (TRIZ) was used to identify surface texturing as a viable option to increase durability of automotive electrical connectors.

“…Several authors have reiterated the potential usefulness in measuring wear in situ rather than relying on post-test profilometry measurements [19,20]. In wear prediction it is often assumed that the wear rate is linear but this is generally not the case, particulary when there is a change in the predominant wear mechanism during the test [20,21]. Table 1 compares the typical conditions in the new capability for nano-scale reciprocating wear to other approaches for multi-pass sliding contacts (repetitive scratch and nano-fretting) with the same instrumentation.…”

“…The surface/near surface microstructure of the alloy may also evolve during sliding and influence the friction. With continued sliding grain refinement and/or formation of a tribologically transformed structure (TTS) has been reported for many alloys [14,21,26,[28][29][30][31][32]. Suresh and co-workers have reported grain refinement resulting in an increase in hardness within the scratch track on Cu [26,30].…”

Reciprocating contacts occur in a wide variety of practical wear situations including hip joints and electrical contacts. In developing tribological tests for candidate materials with improved durability in these contacts it is beneficial that the contact conditions (e.g. sliding speed) can be reproduced. Hence, a fully instrumented capability for rapid high-cycle linear reciprocating nano-scale wear tests has been developed. It is multi-sensing with high data 2 acquisition measurements of probe displacement data, friction, cumulative frictional energy dissipation and electrical contact resistance. In comparison with other nanoindenters the design has the high level of lateral rigidity which provides sufficient stability to perform nano-or micro-scale wear tests for extended duration (e.g. several hours, up to 300 m sliding). In this study, reciprocating nano-wear tests with diamond probes have been performed on the biomedical alloys Ti6Al4V and 316L stainless steel, and with electrically conductive metallic probes on gold and silver alloys. The stainless steel exhibited a ductile response with low friction throughout the load range. At higher loads on Ti6Al4V, there was an abrupt transition to higher friction and fracture-dominated wear after ~20 cycles.Improved detection of the onset of wear and the subsequent failure mechanisms sliding against conductive probes was possible by a multi-sensing approach simultaneously monitoring friction and electrical contact resistance (ECR). Changes in ECR exhibited a complex correlation with changes to the measured friction. The reciprocating tests of noble metal-noble metal contacts (Au-Au and Ag-Ag) showed much longer endurance than gold vs. steel contacts although occasional isolated failures were observed. A new approach for the analysis of repetitive nano-scratch test data was also developed enabling improved data mining.
