About this Research Topic
Tribo-systems are complex systems with many elements, and modelling of their behaviour requires an accurate description of system elements. Operationally optimised surface textures, such as plateau honing with laser marks in engine cylinders, or micro-lubricating surface modification in case of bearings, increase the tribological performance of machine elements. Hybrid materials – such as composites or metal foams – provide better material and tribological behaviour. These technologies, in addition to their advantages, pose challenges in the characterisation of surfaces. Proper identification and description of surface features are important parts of the design of tribologically effective surfaces, and in the qualification of production of machine elements.
The goal of this Research Topic is to present new methods and new approaches in the characterisation of microtopographic (3D) surfaces, and to discover the relationships between surface structure and tribological behaviour. Manuscripts about the novelties of different surface roughness characterisation techniques are expected. This Research Topic will focus on the identification and characterisation of surface features: asperities, valleys, tool marks; wear marks, orientation and other dominant and important elements of microtopographies. New perspectives on 3D surface roughness characterisation of engineering surfaces in both production and tribological operation is approved. In the case of production technologies, the main goal is to present a method to characterise the decisive surface element that connected the process parameters. From the point of view of tribology, the importance is the characterisation of microtopographic features that play a major role in operation. Papers about the effects of surface structure on tribological properties are awaited and approved.
