Dynamic evolution of interface roughness during friction and wear processes

Abstract

This is the pre-peer reviewed version of the following article: Kubiak K.J., Bigerelle M., Mathia T.G., Dubois A., Dubar L., Dynamic evolution of interface roughness during friction and wear processes. Scanning Vol 36 (2014) After an initial period of rapid degradation, dynamic evolution of surface roughness converges to certain level specific to a given tribosystem. However, roughness at such dynamic interface is still increasing and analysis of initial roughness influence revealed that to certain extent, a rheology effect of interface can be observed and dynamic evolution of roughness will depend on initial condition and history of interface roughness evolution. Multiscale analysis shows that morphology created in wear process is composed from nano, micro and macro scale roughness. Therefore, mechanical parts working under very severe contact conditions, like rotor/blade contact, screws, clutch etc. with poor initial surface finishing are susceptible to have much shorter lifetime than a quality finished parts.

Non-destructive identification of pull-off adhesion between concrete layers

“…As presented in [28][29][30][31][32], the tests providing the basis for the methodology were carried out on two 2500 × 2500 mm model concrete Table 1 Synthetic description of 3D laser scanning method [37][38][39][40][41][42][43][44][45][46][47][48][49][50].

“…The methodology uses parameters estimated on the concrete substrate layer surface by the latest 3D laser scanning method [37][38][39][40][41][42][43][44][45][46][47][48][49][50] and parameters estimated on the floor surface by the impulse response and impact-echo methods [51][52][53][54][55][56][57][58][59] and ANN.…”

Topographic characterization of canine teeth using atomic force microscopy images in nano-scale

“…PSD is defined as the square of surface roughness amplitude versus wavelength which is applied to compare surface quality quantitatively [14]. AFM images are for PSD analysis as presented in Fig.…”
