Measurement of deformation in rolling and sliding contacts

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