Abstract
The friction of materials has long been understood as the collective contact and interaction of microasperities. The rise of micro- and nanomechanical instruments allows the study of single microasperity contact to understand fundamentally friction and wear. This study investigates the deformation due to a single microasperity, which performs a single stroke scratch in austenite. We find that the elastic and plastic equations for static indentation also apply for the dynamic scratching. Additionally, the friction coefficient is found to be normal force dependent and we observe three domains: microstructure dominated friction, plastic plowing dominated wear and wear particle dominated tribology.
