“…Figure 5 represents the biological structure of HSA. The effect of albumin and its interaction with other SF components on lowering friction is due to its negative charge; this has been shown by a few studies [70][71][72][73].…”

In this study, we have disclosed in which way the perennially alive Coulomb-Amontons law of friction can be called upon its plausible extension toward (bio)nanoscale. We have rather addressed an applied (biological) physics’ practical problem, and have sketched how it can be solved in a semi-quantitative hybryd-type way. We have provided a strong evidence on which nanotribopairs one ought to rest in order to solve eﬃciently the friction–lubrication, and to some extent, wear viz structural deﬁciency problem of articular devices, the latter being envisioned as a fundamental biomimetic problem. Of course, the main quest addressed has not been solved in full, but some partial semi-quantitative solutions on ultralow coeﬃcient of friction have been given, and critically discussed.

The presented study deals with the analysis of the tribological behaviour of the Ti6Al4V alloy manufactured conventionally. The study aimed to verify whether the titanium alloy is suitable for use as a contact material in small joint implants, as additive manufacturing of this alloy can in the future provide certain benefits, such as individualization and simplification of the implant construction, or controlled porosity. The tested pair consisted of a pin and a glass plate lubricated with model synovial fluid. The contact area was observed with colorimetric interferometry. Alongside film thickness, friction, and wear scars were measured. From the designed experimental conditions, the titanium alloy was not able to create a sufficiently thick lubrication film to overcome its surface roughness and damage to contact surfaces occurred. Friction was comparable for all the tested configurations. The application of conventionally manufactured titanium alloy as a contact surface in small joint implants seems to not be suitable since its performance fell short when compared to conventional cobaltous alloy. Nevertheless, there are various alternative methods available, such as unconventional manufacturing, polishing, surface texturing, and coating. Graphical Abstract
