This work was aimed to study on how wear of engineering polymers depends on the topography of counter-surfaces of non-Gaussian type. Instead of widely used Gaussian distribution of surface heights, the Weibull distribution was used here to model aspe

This paper proposes a wear model for polymers based on so-called mechanistic processes comprising both low cycle fatigue and abrasive wear mechanisms, which are prominent in polymer–metal sliding interfaces. Repeated elastic contact causes localize

Wear debris on sliding tracks can often be a significant contributing factor to the friction and wear behaviors of polymer–metal sliding systems. This paper disseminates insightful examinations on the variegated patterns of PEEK wear debris and the

This paper attempts to demonstrate a systematic spectral approach for the characterization of the topographic nature of rough surfaces. Multiscale roughness characterization reveals a panoramic structure of microgeometric features of engineering surf

PurposeAlthough dependence of contact surface temperatures between rough sliding bodies on surface topography is more explicitly described in terms of three‐dimensional (3D) topographic parameters, no work has yet been reported on this aspect. The

A theoretical model for analyzing surface temperature rise between extremely smooth sliding bodies considering the effect of adhesion forces on the contact conditions is developed. The important observation is that in addition to the dependence on lo

Prediction of contact temperature rise between sliding bodies is difficult due to the large number of parameters that affect the contact phenomenon. It is far more complex if the instantaneous roughness of the sliding pair is taken into consideration

Because of its industrial relevance, wear of engineering polymers has been studied extensively both experimentally and theoretically. The wear mechanism of polymers is complex due to the influence of numerous parameters and it has long been realized
