Thermal-Induced Wear Mechanisms of Sheet Nacre in Dry Friction

“…The probe rate is 100 µm.s -1 . This latter is sufficiently weak so that the heat transfer regime stays in the steady state conduction as in the tribological tests [11,15]. The spatial resolution and the thermal sensitivity are, respectively, about 100 nm and 1°C [15].…”

“…This latter is sufficiently weak so that the heat transfer regime stays in the steady state conduction as in the tribological tests [11,15]. The spatial resolution and the thermal sensitivity are, respectively, about 100 nm and 1°C [15]. Calibration of the SThM is made by using three reference polymeric samples [14]: PAI TORLON (T g = 285°C), PEI ULTEM1000 (T g = 215°C), PPS (T g = 94.4°C, T f = 281°C).…”

Finite Element Analysis of the Material’s Area Affected during a Micro Thermal Analysis Applied to Homogeneous Materials

“…As an example, Depasse et al [21] refer to some 30 nm radius for this zone. This study however deals with an 80 nm radius according to Gomes et al's work [10,12,16] that are more successfully completed in regard to the analysis and the understanding of classical micro thermal analysis measurements with standard probes.…”

“…Using analytical models, several authors have been able to quantify the dimensions of this contact area. So, Gomes et al [16] The thermal probe is replaced by a simplified thermal condition applied to the sample surface: the temperature increase of 15 ˚C/s (thermal loading of the probe) is supposed to be applied on a small surface of the sample equivalent to the probe contact area. The radius of this area is fixed at 80 nm according to the results of Gomes et al [16] and the presence of the water meniscus is not taken into account in the first step.…”

“…Three angles are arbitrary fixed for the probe in the study: 15˚, 45˚ and 85˚ (Figure 12). The length of the contact zone between the meniscus and the sample is constant and equal to 206 nm whatever the angle of the probe is [16]. The thermal condition used in previous simulation was applied on a new probe contact area (the sample surface and the water meniscus surface in contact with the thermal probe - Figure 12).…”
