Within this research line at IPHES-CERCA, advanced microscopy and 3D surface analysis are used to understand bone-surface modifications related to human behavior, violence, cannibalism, and funerary practices in archaeological contexts.
Tribology
This study successfully achieved a comprehensive quantitative and qualitative characterization of solid particle erosion (SPE) in bulk alumina, neat epoxy resin, and alumina-reinforced polymer composites under different impact angles and velocities.
In this study, the different surface topographies obtained through the 3D profiler provide valuable insights into using ground stone and obsidian tools. These observations help us to further explore dietary practices and the evolution of human-plant interactions over time, as well as trace the development of more complex socioeconomic systems and social networks.
In this study with an automotive company, we have proof how laser texturing enhances the functional performance of cylinder liner segments. Adding up the analysis software capabilities, we have assessed the frictional performance of the laser-textured surface.
Our research focuses on improving tribomechanical properties of Diamond-Like Carbon (DLC) coatings, deposited by the novel PVD technique High Power impulse magnetron sputtering (HiPIMS) with positive pulses on tool steels.
The case study focuses on the development of nanocomposite W-C:H coatings with high hardness and simultaneously, with a lower coefficient of friction.
