These experiments are often conducted within the parameter space of the micro-machine and at constant load and sliding velocity. In reality, the contact loadings are time dependent and, in particular in the case of micro-machines, fast moving and rapidly changing. Using twin-wheel experiments, the wear law for the contacting materials is determined in form of the wear coefficient included in Archard's wear model. For the prediction of wear in more complex systems, a numerical simulation tool has been developed, which incorporates the identified wear model. This so-called Wear-Processor is capable of a fully transient wear integration scheme and is used to simulate wear in a micro gear, which is currently being developed within the collaborative research centre SFB 499. First results give an impression how fast the gear tooth geometry and the slip rates deviate from their original shape as a consequence of ongoing wear. © 2009 Wiley-VCH Verlag GmbH & Co.
