Surface roughness has a huge impact on many important phenomena. The most important property of rough surfaces is the surface roughness power spectrum C(q). We present surface roughness power spectra of many surfaces of practical importance, obtained from the surface height profile measured using optical methods and the atomic force microscope. We show how the power spectrum determines the cont...

Slips and falls can happen in any part of the flat or home, but is more common on stairs and in the kitchens and bathrooms. The present paper investigates the friction between rubber and leather footwear on one side and different flooring materials on the other side. Ceramics, Concrete and Granite tiles are tested. Both dry and wet contamination agents are considered. The ultimate results are s...

Abstract Diamond-like carbon (DLC) films directly deposited on rubber substrate is undoubtedly one optimal option to improve the tribological properties due its ultralow friction, high-hardness as well good chemical compatibility with rubber. Investigating relationship between film structure and performance vital for protecting In this study it was demonstrated that etching effect induced by hy...

This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibil...

We study the influence of surface energy and contamination films on rubber adhesion sliding friction. find that there is a transfer molecules from to substrate which reduces work makes friction insensitive energy. show no simple relation between friction: due (vertical) detachment processes at edge contact regions (opening crack propagation), while in many cases determined mainly by (tangential...
