Abstract Diamond-like carbon (DLC) films are deposited on rubber surfaces to protect the components, and surface pretreatment of substrates prior film deposition can improve adhesion between DLC rubber. Thus, principal purpose this work concentrates determining effects argon (Ar), oxygen (O 2 ), nitrogen (N hydrogen (H ) plasma pretreatments friction performance (DLC/rubber). The results indica...

Abstract We study the influence of rubber transfer films on sliding friction between rectangular blocks and a concrete surface. present experimental results for coefficient compound surface contaminated by another compound, two different pairs (A, B) (C, D) compounds. For same compounds, we theory which illustrate relative importance viscoelastic adhesive contribution to friction. correlate cal...

Abstract This paper is devoted to an analytical, numerical, and experimental analysis of adhesive contacts subjected tangential motion. In particular, it addresses the phenomenon instable, jerky movement boundary contact zone its dependence on surface roughness. We argue that “adhesion instabilities” with instable movements cause energy dissipation similarly elastic instabilities mechanism. lea...

The ability of an automobile tyre to ‘grip’ the road and avoid skidding is ultimately dependent upon the events in the tyre-road interface. This seems obvious, and yet some 70 years after pneumatic rubber tyres were first put to use we are not able to explain fully the frictional processes between the tyre and the road. Over 650 papers have been published prior to 1970 on some aspect of tyre be...

This work aims at enhancing the understanding and to provide improved models of the dynamic behavior of rubber vibration isolators which are widely used in mechanical systems. Initially, a time domain model relating compressions to component forces accounting for preload effects, frequency and dynamic amplitude dependence is presented. The problem of simultaneously modelling the elastic, viscoe...

It is generally assumed that fingerprints improve the grip of primates, but the efficiency of their ridging will depend on the type of frictional behaviour the skin exhibits. Ridges would be effective at increasing friction for hard materials, but in a rubbery material they would reduce friction because they would reduce contact area. In this study we investigated the frictional performance of ...

A quantitative method, using temperature-controlled friction force microscopy (FFM), has been developed to determine the frictional (dissipative) character of thin polymer films. With this method variations in friction are sampled over micrometer-scale regions and are reduced to “friction histograms,” yielding the distribution of frictional forces on the surface. The temperature dependence of t...
