Abstract Microstructural alteration of tribo-elements' the near-surface region significantly affects how long a tribosystem will last. To design and tailor future surfaces of tribo-elements, a fundamental understanding of microstructure evolution under local tribological exposure is required. During the initial steps of macrotribological process in metals, horizontal dislocation walls have been observed, which later develop into the grain-refined tribolayer, however, their fundamental mechanisms are yet unknown. In this work, we developed a novel micro-tribological test, in order to directly inspect the contact zone and simplify the stress status. Our preliminary basic tribological experiments identify grain orientation and twin boundary effects in dry… More >

Abstract The field of nanotribology in the last decades was established through the introduction of Atomic Force/Friction Force Microscopes. However, our theoretical understanding of the individual processes involved in friction force microscopy is limited. This work designs a reliable and efficient model for the stickslip phenomenon, following the rules of network simulation. The model is able to manage different types of potential between the tip and the sample surface, allowing different kinds of sample material and microscope tip properties to be simulated with only minor changes in the code. The most analysed tribological materials in technical literature are simulated to test… More >
