Measurement of deformation in rolling and sliding contacts

Abstract

In this work, mechanisms behind micro-scale changes on the surfaces in\ud rolling and sliding contacts are studied both experimentally and\ud numerically. For the experimental study a wear and deformation\ud measurement system is designed and produced. This system is composed of\ud an interference microscope, a controllable rotating table and a friction\ud device. The system allows measurement of the micro and nano-scale local\ud changes on the surface micro-geometry during a wear or deformation\ud experiment
