“…Despite this motivation related to both fundamental and technological aspect, so far, there are only few systematic tribological studies of glasses at high temperatures. In principle, most current tribometers are optimized for the general analysis of friction and wear between hard surfaces close to room temperature either in dry or lubricated environments [27][28][29][30][31][32][33]. Nonetheless, high-temperature systems are also available, but they are rather applied to hard contacts between ceramics [34] or metallic materials, with the analysis of metallic glasses [35] or steel [36] as prominent examples.…”

Tribological Analysis of Contacts Between Glass and Tungsten Carbide Near the Glass Transition Temperature

In recent years, the tribological contact between hard solids and glass at high temperatures has been identified as a crucial aspect in emerging technical applications like e.g., precision glass molding. To optimize such tribological systems, especially, the internal transformations of the glasses need to be considered, since these can determine which kind of energy dissipation channels become relevant, when the temperature of a glass is increasing and approaching the glass transition temperature. Here, we now introduce a new tribometer specifically developed for the analysis of glasses at elevated temperatures. Using this tribometer, we characterize friction of contacts between tungsten carbide (WC) and soda lime glass as a function of temperature, while additionally PMMA was analyzed for comparison. Our experiments reveal different tribological regimes where either simple sliding, surface fracturing, or surface deformation can be identified as relevant interface processes for the tribological behavior.

“…Recently, renewed interest for relaxation tribometry has emerged as a unique tool to measure low forces efficiently and accurately [9,10,11]. The reason is that the smaller the friction force, the smaller the decrement, the more measurable oscillations before rest and thus the more data available to estimate the force.…”

Relaxation Tribometry: A Generic Method to Identify the Nature of Contact Forces

et al. 2019

Recent years have witnessed the development of so-called relaxation tribometers, the free oscillation of which is altered by the presence of frictional stresses within the contact. So far, analysis of such oscillations has been restricted to the shape of their decaying envelope, to identify in particular solid or viscous friction components. Here, we present a more general expression of the forces possibly acting within the contact, and retain six possible, physically relevant terms. Two of them, which had never been proposed in the context of relaxation tribometry, only affect the oscillation frequency, not the amplitude of the signal. We demonstrate that each of those six terms has a unique signature in the time-evolution of the oscillation, which allows efficient identification of their respective weights in any experimental signal. We illustrate our methodology on a PDMS sphere/glass plate torsional contact.
